The area of the general human activities, the area of the key human activities, and the area of natural ecological lands with excellent and good ecological quality can be obtained from the remote sensing image, which can be generated by remote sensing of UAV aerial remote sensing equipment or a high-resolution satellite (such as a high-resolution satellite whose solution ratio is less than 2 m). When the resolution ratio of the remote sensing image is relatively high (such as being higher than a set resolution threshold), a natural forest and grass region, a natural wetland region, a desertification/desertification/rocky desertification region, a region of the general human activities, a region of the key human activities can be extracted according to form of each light spot in the remote sensing image to obtain the corresponding area. Other data can be obtained from the database. Each county-level local government can obtain various data needed through a ground survey, and then send the various data to a server through a network and store the data in the database. In addition, part of the data are calculated and obtained via model simulation and data analysis. During the evaluation, data can be directly called from the database to obtain each evaluation data.

Step 120: performing calculation according to the evaluation data of the ecological function to obtain a function maintenance index of the evaluation region.

Quantitative evaluation is mainly carried out for the evaluation data of the LUS00161 ecological function, the protection area, and the land use property.

In step 110, the remote sensing image in the evaluation region is first obtained, and the remote sensing image is generated by aerial remote sensing by an UAV and/or the remote sensing by the high-resolution satellite. Meteorological data, index coverage data, and basic soil data in the evaluation region are stored in the database. According to the forgoing stored data and the obtained remote sensing image, a geographic information system (GIS) is used to perform raster operation to obtain the evaluation data of the ecological function. A calculation process for the evaluation data of the ecological function is as follows: The water conservation service function amount is calculated by a water balance equation: TO = SPP —RR —ET)x A x107 i=l Where TQ represents the water conservation service function amount, that is, total water conservation amount, m*; PPirepresents average rainfall amount over the years, mm; RRirepresents average surface runoff over years, mm; ET; represents the average evapotranspiration over years, mm; Ai represents the area of an i-th category ecosystem, km”; i represents type of the i-th category ecosystem in the evaluation region; and j represents the number of types of the ecosystems in the evaluation region.

The biodiversity maintenance service function amount is calculated using a method for correcting a net primary productivity NPP: Spo = NPP... X Fre X From x (1= Fou).

Where Suis is the biodiversity maintenance service function; NPPmean is an LUS00161 average value of net primary productivity of vegetation over years; Fpre is an average precipitation amount over years; Fem is average temperature over years, and Far is an altitude factor.

The water and soil conservation service amount is calculated using a water and soil conservation service model of a Revised Universaliooil Loss Equation (RUSLE) : A = A,—- A, =RxKxLxSx(1-C).

Where Ac is the water and soil conservation service function amount, that is, the water and soil conservation amount (t/hm?xa); Ap is potential soil erosion amount; Ar is actual soil erosion amount; R is a rainfall erosivity factor (MJ xmm/hm2x hx a); Kis a soil erodibility factor (tx hm2 xh/hm2xMJxmm); L and S are terrain factors, L represents a slope length factor, S is a slope gradient factor; and C is a vegetation coverage factor.

The wind protection and sand fixation service function amount is calculated using the revised wind erosion equation: SR = Siena = S ; | Where SR is the wind protection and sand fixation service function amount, namely sand fixation amount (t km? a-1); SL potential is potential wind erosion amount (t km? a-1); Si is actual wind erosion amount (t km? a-1).

The water loss and soil erosion sensitivity index is multiplied according to the basic principles of a general Universaliooil Loss Equation according to a single factor evaluation data reflecting sensitivity of each factor to soil erosion by using geographic information system software, and the formula is as follows:

Where SSi represents the water loss and soil erosion sensitivity index of a spatial unit i; Ri represents rainfall erosivity; Ki represents soil erodibility; LS; represents slope length and slope gradient; and Ci represents vegetation coverage.

The land desertification sensitivity index uses a spatial analysis function of the geographic information system software to perform multiplying calculation according to a sensitivity distribution map of each single factor to obtain a soil desertification sensitivity level distribution map of the evaluation region, and the formula is as follows: D,= 1, <W <KK,xC, Where Di represents the land desertification sensitivity index of the evaluation region i; li represents an aridity index of the evaluation region; Wi represents the number of days with sand and wind; KKi represents soil texture; and Ci represents the vegetation coverage.

According to a formation mechanism of rocky desertification, the rocky desertification sensitivity index uses a spatial overlay function of the geographic information system software to perform multiplying operation on a sensitivity distribution map of each single factor to obtain a rocky desertification sensitivity level distribution map, and the formula is as follows: S, = DD, x PPP xC, Where Si represents the rocky desertification sensitivity index in the evaluation region i; DD; represents the percentage of carbonate rock outcropping area in the evaluation region i; PPPirepresents the slope gradient of a terrain; and Cirepresents the vegetation coverage.

After obtaining the evaluation data of the forgoing ecological functions, LUS00161 please see FIG. 2. In step 120, the function maintenance index includes the following calculation steps: Step 121: calculating a ratio of a sub-data value of an evaluation period to a sub-data value of a base period, and performing match from a preset score table to obtain a score corresponding to the ratio according to a plurality of sub- data in the evaluation data of the ecological function.

Here, the value of the evaluation period is the value when a year is evaluated. The value of the base period for a first evaluation after the ecological conservation redline is delineated is a background value obtained from initial basic investigation and statistical analysis after the ecological conservation redline is delineated. The value of the base period thereafter is the value of a previous round of evaluation years.

Step 122: multiplying the corresponding score by a weight corresponding to the sub-data to obtain a product result, and uses a correction coefficient in the evaluation region to correct the product result to obtain an indicator score corresponding to the sub-data.

A correction coefficient q represents a contribution rate of human activities.

Because data including ecological quality, ecological function are significantly affected by climate conditions of that year, for this part of the data of this embodiment, the correction coefficient q is obtained by calculating a contribution rate of climate change and the human activities to the protection effectiveness of the ecological conservation redline to distinguish the impact of meteorological conditions on the protection effectiveness of ecological conservation redline.

Optionally, this embodiment selects the net primary productivity NPP, an LUS00161 indirect indicator that characterizes an ecosystem service function, to determine a contribution rate of climatic conditions to the protection effectiveness of the ecological conservation redline.

Therefore, the evaluation method further includes: using a net primary productivity NPP evaluation model to calculate NPP values of the evaluation period and the base period of the ecological conservation redline under average climatic conditions and real climatic conditions, respectively; and calculating the correction coefficient q, and the formula is as follows:

Where Ga and Gap are the NPP values of the evaluation period and the base period of the ecological conservation redline under the average climatic conditions, and Gn and Grp are the NPP values of the evaluation period and the base period of the ecological conservation redline under the real climatic conditions, respectively.

The NPP evaluation model can be a solar energy utilization efficiency (Carnegie-Ames-Stanford-Approach, CASA) model.

Specifically, a vegetation classification map, a normalized vegetation index NDVI, meteorological data (monthly average temperature, monthly total precipitation amount, monthly value data of solar radiation), digital elevation model DEM data, and administrative division data are first obtained and taken as input data of the CASA model.

The CASA model calculates the forgoing input data to obtain the photosynthetically active radiation APAR, an actual light energy utilization rate €, and the net primary productivity NPP (the first two data are used as intermediate data for the NPP calculation), and then can output the net primary productivity NPP value according to the CASA model to calculate the correction coefficient q. LUS00161 Step 123: adding up an indicator score corresponding to each sub-data to obtain the function maintenance index of the evaluation region.

After steps 121-123, calculation is performed to obtain the function maintenance index of the evaluation region.

Continuing to refer to FIG. 1, Step 130 is performed: performing calculation according to the evaluation data of the protection area to obtain an area retention index of the evaluation region.

Specifically, the following formula is used to calculate the area retention index ER in the evaluation region: ER = (2) x 100%; Where Sa represents the area of the ecological conservation redline of the evaluation region in the base period; Pirepresents the regulation and increase area of the ecological conservation redline of the evaluation region; and Pr represents the regulation and reduction area of the ecological conservation redline of the evaluation region.

Step 140: performing calculation according to the evaluation data of the land use property to obtain a human disturbance index and an ecological quality index of the evaluation region.

Step 140 includes calculation of the human disturbance index and calculation of the ecological quality index.

Specifically, please refer to FIG. 3, the human disturbance index has the following calculation steps: Step 141: calculating the ratio of the sub-data value of the evaluation period to the sub-data value of the base period, and performing match from the preset score table to obtain the score corresponding to the ratio according to LUS00161 the plurality of sub-data in the human disturbance data.

The plurality of sub-data in the human disturbance data includes the area of the general human activity, the area of the key human activities, and the fragmentation degree of the redline patch. Scores corresponding to regions with different ratios are pre-allocated in the preset score table.

Step 142: multiplying the corresponding score by the weight corresponding to the sub-data to obtain an indicator score corresponding to the sub-data.

Step 143: adding up an indicator score corresponding to each sub-data to obtain the human disturbance index of the evaluation region.

Specifically, please refer to FIG. 4, the ecological quality index has the following calculation steps: Step 144: calculating the ratio of the sub-data value of the evaluation period to the sub-data value of the base period, and performing match from the preset score table to obtain the score corresponding to the ratio according to the plurality of sub-data in the ecological quality data.

The plurality of sub-data in the ecological quality data includes the area of the natural ecological land and the area of the ecosystems with excellent and good ecological quality. The area of the ecosystems with excellent and good ecological quality can be calculated by using ecosystem surface parameters (including above-ground biomass, a leaf area index, and the vegetation coverage) a period of ten days by a period of ten days or year by year from the evaluation period to the base period that are obtained by remote sensing interpretation. Ecological quality is expressed by relative biomass density according to remote sensing image pixels.

The relative biomass density is a ratio of the biomass of the ecosystem LUS00161 according to the pixels to the maximum biomass of the ecosystem type. Calculation method is as follows: RBD;; = or x 100%; Where RBDj represents the relative biomass density of a pixel i of the ecosystem |; Bi represents the biomass of the pixel i of the ecosystem |, which is obtained through remote sensing; CCB; represents the biomass per pixel of a top community of the ecosystem j, which is obtained according to long-term positioning observation data of the ecosystem or sample plot survey data (stored in the database). According to the value of RBDj, the quality of the ecosystem is classified into excellent, good, medium, poor, and inferior grades.

Step 145: multiplying the corresponding score by the weight corresponding to the sub-data to obtain the product result, and using the correction coefficient in the evaluation region to correct the product result to obtain the indicator score corresponding to the sub-data.

Step 146: adding up an indicator score corresponding to each sub-data to obtain the ecological quality index of the evaluation region.

After steps 141-146, calculation is performed to obtain the human disturbance index and the ecological quality index.

Continuing to refer to FIG. 1, step 150 is performed: performing calculation according to the evaluation data of the management ability to obtain a management ability index of the evaluation region.

For data of management ability, qualitative evaluation is mainly carried out.

The plurality of sub-data of the management ability is performed with qualitative evaluation and assigned with a score. When evaluation is performed,

the preset score table is first obtained from the database. Match is performed LUS00161 according to the preset score table to obtain the score corresponding to each sub-data. The corresponding score is then multiplied by the weight corresponding to the sub-data to obtain the indicator score corresponding to the sub-data. Finally, the indicator score corresponding to each sub-data is added up to obtain the management ability index of the evaluation region.

Step 160: adding up the function maintenance index, the area retention index, the human disturbance index, the ecological quality index and the management ability index to obtain a protection effectiveness comprehensive index.

The protection effectiveness comprehensive index in Step 160 is a sum of the function maintenance index, the area retention index, the human disturbance index, the ecological quality index and the management ability index. The protection effectiveness comprehensive index is used to reflect the protection effectiveness of the ecological conservation redline in the evaluation region. Therefore, by calculating the protection effectiveness comprehensive index, it is possible to accurately and comprehensively quantify the protection effectiveness of the ecological conservation redline in the evaluation region.

For example, according to the numerical value of the protection effectiveness comprehensive index and a pre-delineated graded interval, the protection effectiveness comprehensive index is quantified into a plurality of levels to reflect changes in the protection effectiveness of ecological conservation redline. A simple example is taken for illustration. For example, when the protection effectiveness comprehensive index is less than 95, it indicates that the protection effectiveness in the ecological conservation redline is in a state of decline, or incremental repair is less than damage. When the LUS00161 protection effectiveness comprehensive index is in the interval [95,105], it indicates that the protection effectiveness in the ecological conservation redline is in a relatively stable state, or is in a balanced confrontation period between ecological restoration and ecological degradation, and a grade is maintained stability. When the protection effectiveness comprehensive index is greater than 105, it indicates that the protection effectiveness in the ecological conservation redline is in a state of improvement, or the incremental restoration is greater than the damage. The grades include mild improvement, moderate improvement and significant improvement.

Through the quantification of the protection effectiveness comprehensive index, a plurality of evaluation results of the same evaluation region can be compared vertically. In addition, a plurality of the protection effectiveness comprehensive indexes in different evaluation regions can also be compared horizontally.

Optionally, in order to facilitate the evaluation method to adapt to features of different regions, a self-selected indicator index can be added in the evaluation process, and the self-selected indicator index mainly reflects features of regional protection. The evaluation data obtained in Step 110 also include evaluation data for feature self-selection. The evaluation data for the feature self-selection include at least one of water environment quality, air environment quality, soil environment quality, the distribution area of invasive alien species, a protection rate of important species, a grassland overload rate and the proportion of an ecological bank.

The water environment quality refers to the annual average concentration of the main pollutants (total nitrogen, total phosphorus, COD) in the ecological 7500161 conservation redline. The air environment quality represents the annual average concentration of the main pollutants (sulfur dioxide, nitrogen dioxide, and inhalable particulate matter) in the ecological conservation redline. A method of obtaining the soil environment quality includes: in the ecological conservation redline of the evaluation region, main soil types are selected according to different sampling densities. A registration sampling method is used to lay out sampling points. Soil environment index content in a surface level (0-20 cm) is taken as a research object. Soil layer data with a depth greater than 20 cm are not processed. For soil layers with a depth less than 20 cm, all soil layers with the depth within 0-20 cm are weighted and averaged to obtain the soil environment quality. The distribution area of the invasive alien species refers to the area where invasion of invasive alien plants and animal species occurs within the ecological conservation redline. For types of the alien species, please refer to species lists issued by relevant departments. The protection rate of the important species refers to the number of population of the important species within the ecological conservation redline. The important species include national first and second level protected species and rare and endangered species in an IUCN red List. Grassland overload rate refers to a ratio of a difference value between actual grazing capacity and theoretical grazing capacity to the theoretical grazing capacity in the ecological conservation redline. The proportion of the ecological bank refers to proportion of banks of rivers and lakes with natural or semi-natural attributes.

The calculation steps of the self-selected indicator index are the same as those of the human disturbance index, which is not repeated here.

In some alternative embodiments, one veto score can be set for part of the LUS00161 sub-data in the preset score table. if a ratio of the data value of the evaluation period of the part of the sub-data to the data value of the base period matches to one veto score, an evaluation process is exited, and the protection effectiveness of the ecological conservation redline in the evaluation region can be directly determined to be unqualified.

Further, after obtaining the protection effectiveness level of the ecological conservation redline in the evaluation region, an evaluation report can be generated according to the various data obtained in the evaluation process. The evaluation report can be used as a basis for layout of the ecological conservation redline, ecological civilization evaluation of a county territory, and leading cadres' evaluation, and can be announced to the public at the same time.

In a specific implementation process, for example, each county-level region in a province is evaluated separately, and the protection effectiveness comprehensive index corresponding to the plurality of county-level regions is sorted.
