Detailed Description
The technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings, and it should be understood that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the description of the present invention, technical features involved in different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
Example 1
The embodiment of the invention provides a wetland ecological water demand calculation method, which mainly comprises the following steps of:
step S10: determining a target protection object in the wetland, wherein the wetland comprises a plurality of protection areas, and each protection area at least corresponds to one target protection object.
In a specific embodiment, the protection areas refer to areas constituting the wetland, and different protection areas have different characteristics, and since the ecological water demand is analyzed and calculated in the embodiment of the invention, the main factor for distinguishing the different protection areas is the water demand, and the water demands of the protection areas are different, for example, the protection areas may include a wetland, a grassland, a water surface, and the like. Since the wetland has spatial heterogeneity, in order to protect the entire wetland, it is necessary to divide the wetland into a plurality of protection regions according to the spatial heterogeneity, and select at least one target protection object in each protection region.
In one embodiment, elements such as aquatic plants, aquatic animals, terrestrial plants, terrestrial animals, water environment and the like in the wetland can be used as target protection objects.
When the target protection object in the wetland is determined, the indicative species in the wetland can be selected as the target protection object, and the indicative species in the wetland is taken as the target protection object because the indicative species is sensitive to the water environment, so that the wetland ecosystem can be better protected while the target protection object is protected.
Step S20: and acquiring historical data of each protection area, and determining the ecological water demand of the target protection object in each protection area in different time periods according to the historical data of each protection area. Since the difference in the ecological water demand of the target protected object in different protected areas is large, each protected area needs to be analyzed separately.
The calculation of the ecological water demand of the target protection object can be the calculation of the ecological water level required by the target protection object or the calculation of the ecological water level required by the target protection object.
In one embodiment, the historical data of the wetland comprises hydrologic factors, hydrodynamic factors, water quality factors, biological factors and the like. Wherein, the hydrological factors comprise precipitation, water quantity, flow, water level and the like; hydrodynamic factors comprise flow speed, water depth and the like, and water quality factors comprise water temperature, dissolved oxygen, transparency, electrolyte, chemical oxygen demand, ammonia nitrogen, total phosphorus, heavy metal and the like; the biological elements comprise fishes, benthonic animals, aquatic plants, birds, amphibians, terrestrial plants and the like, and the acquisition of the data of the biological elements refers to the acquisition of ecological indexes of organisms, such as: plant biomass, coverage, number of plants, height, number of fish, species of fish, location and area of fish habitat, location and area of bird habitat, species and number of birds, species composition and number of benthos, etc., different organisms have different ecological indexes. In order to more accurately analyze and calculate the water demand of a target protection object in the wetland, historical data of factors such as hydrology, hydrodynamic force, water quality, biology and the like have synchronism, and the data have a corresponding relation in time so as to analyze the response relation of ecological hydrology-hydrodynamic force-water environment quality-ecology.
When determining the ecological water demand of the target protection object in different time periods according to the historical data of the protection area, determining the ecological water demand of the target protection object in different time periods according to the water amount corresponding to the best state of the target protection object in different time periods according to the historical data. Since the characteristics of different target protected objects are different, the criteria for judging the state of different target protected objects are also different, for example, when the target protected object is reed, the state of reed can be judged according to the coverage, the number of plants, the height and the like of the reed in the historical data.
Step S30: and if the protection area corresponds to a plurality of target protection objects, determining the ecological water demand threshold ranges of the protection area in different time periods according to the ecological water demand of the target protection object with the minimum ecological water demand and the ecological water demand of the target protection object with the maximum ecological water demand in the protection area in each time period.
For example, as shown in fig. 2, the ecological water demand of different target protection objects in the same protection area in different time periods, in the same time period, there are a target protection object with the largest ecological water demand and a target protection object with the smallest ecological water demand, so the ecological water demand threshold range of the protection area can be determined according to the ecological water demand of the target protection object with the largest ecological water demand and the ecological water demand of the target protection object with the smallest ecological water demand in each time period.
Step S40: and determining the ecological water demand of the wetland in different time periods according to the ecological water demand of the target protection object in each protection area in different time periods and/or the ecological water demand threshold range of each protection area in different time periods.
In a specific embodiment, when a plurality of target protection objects are arranged in each protection area, determining the ecological water demand of the wetland in different time periods according to the ecological water demand threshold range of each protection area in different time periods;
when only one target protection object exists in each protection area, determining the ecological water demand of each target protection object as the ecological water demand of the protection area corresponding to each target protection object, and then determining the ecological water demand of the wetland in different time periods according to the ecological water demand of each protection area;
when a plurality of target protection objects exist in a part of protection areas and one target protection object exists in the part of protection areas, the ecological water demand of the wetland in different time periods can be determined according to the ecological water demand threshold range of the protection areas containing the plurality of protection objects and the ecological water demand of the protection area containing one protection object.
In a specific embodiment, when determining the ecological water demand of the wetland, the ecological water demand of the target protection object in each protection area in different time periods and/or the ecological water demand threshold range of each protection area in different time periods can be weighted and calculated according to the weight value of each protection object, so as to calculate the ecological water demand of the wetland. Specifically, for the selection of the weight of each protected object, the sensitivity of each protected area to the ecological hydrologic index may be determined according to the response relationship between the biological characteristics of the target protected object in each protected area and the ecological hydrologic index, and a greater weight is given to the protected area with a higher sensitivity, and a smaller weight is given to the protected area with a lower sensitivity. Exemplarily, as shown in fig. 3, the ecological water demand and/or the ecological water demand threshold range of three protected areas of the marsh, the grassland and the water surface are determined according to the determined ecological water demand in different time periods of the wetland when the ecological water demand is the ecological water level.
The wetland ecological water demand calculation method provided by the embodiment of the invention comprises the steps of firstly determining target protection objects in the wetland, determining at least one target protection object corresponding to each protection area when determining the target protection objects, determining the ecological water demand of each target protection object in different time periods according to historical data of each protection area after determining the target protection objects, and finally determining the ecological water demand of the wetland in different time periods according to the water demand of each target protection object in different time periods, wherein the wetland comprises a plurality of protection areas, and the characteristics of the target protection objects in different protection areas are different, the target protection objects in different protection areas are researched and analyzed, so that the finally obtained water demand of the wetland can be comprehensively protected to the protection areas with different characteristics, and the same protection area also has different characteristics in different time periods, the water requirements are different, so the ecological water requirements of the target protection object in the same protection area in different time periods are researched and analyzed, and the finally obtained wetland ecological water requirements can more accurately protect the wetland ecosystem in different time periods. In conclusion, by implementing the wetland ecological water demand calculation method provided by the invention, the ecological process of the wetland ecosystem can be described in a refined manner, the ecological water demand of the wetland can be accurately calculated, dynamic quantitative management can be scientifically implemented, and target protection objects in the wetland and the wetland can be protected.
