Step S13: and outputting and setting the sponge city evaluation model by using the evaluation index to obtain the set sponge city evaluation model.
Step S14: and inputting the target rainwater professional parameters into the set sponge city evaluation model to obtain an output index value.
It should be noted that, for the same sponge city evaluation model, the output index values corresponding to different evaluation indexes are different, and the evaluation indexes need to be used to perform output setting on the sponge city evaluation model. It can be understood that, the parameters in the set sponge city evaluation model are not changed, and only the output contents are different. The sponge city evaluation model is different from the sponge city evaluation model corresponding to different sponge city projects of the target sponge city project.
In the invention, the output index value corresponds to the evaluation index, and different evaluation indexes can be set based on requirements, so that flexible configuration of the output index value is realized.
Further, before the step of performing output setting on the sponge city evaluation model by using the evaluation index to obtain the set sponge city evaluation model, the method further includes: acquiring historical meteorological parameters, basic land parcel parameters, basic sponge parameters, hydrological and hydraulic parameters, water quality parameters and drainage system parameters of the target sponge city project; generalizing the LID by using the basic parameters of the land parcel and the parameters of the drainage system to obtain an LID model; constructing a sponge model by using the basic sponge parameters; constructing a hydrological model by utilizing the hydrological water conservancy parameters and the historical meteorological parameters; constructing a water quality model by using the water quality parameters and the historical meteorological parameters; constructing an inland inundation model by using the drainage system parameters; and obtaining the sponge city evaluation model based on the LID model, the sponge model, the hydrological model, the water quality model and the waterlogging model.
It should be noted that the historical meteorological parameters include historical air temperature, historical rainfall intensity, historical evaporation capacity, historical typical annual rainfall curve and historical rainfall recurrence period; the basic parameters of the land parcel comprise catchment subareas, catchment areas, gradients, different land utilization area proportions and land parcel widths; the actual monitoring data comprises the monitored flow of the sponge facility, the liquid level of the sponge facility and the water quality of the sponge facility; the basic parameters of the sponge comprise sponge facility type, sponge area, surface overflow width, impervious area proportion, water storage depth, vegetation volume proportion, surface roughness coefficient, gradient, impervious rate, permeability, blocking factor, soil texture grading parameter value and water pouring rate gradient; the hydrological and hydraulic parameters comprise catchment subareas, runoff yield model setting, infiltration rate, attenuation rate coefficient, infiltration amount, Manning coefficient, impervious area ratio and impervious rate; the water quality parameters comprise an accumulation function, an accumulation amount area, a rate constant, a scouring curve, a scouring coefficient, a runoff rate index, a cleanable rate, a cleaning time and a land type; the parameters of the drainage system comprise the structure of the drainage system, the subareas of the drainage system and the pipe network data of the drainage system. The historical meteorological parameters are meteorological parameters corresponding to the target sponge city project at the historical moment.
Specifically, the map basic parameter is a map basic parameter for performing data generalization, boundary setting, and parameter setting on the green land LID, the road LID, and the map LID. Road LID generalization: and (3) carrying out generalized setting on the biological retention facilities of the road LID, distinguishing green areas and boundaries of the built road and the non-built road, and defining pollution control indexes of self-absorption of the road and absorption of the green areas. Green land LID generalization: the method can be used for generalizing and setting sponge facilities such as a sunken greenbelt, a wetland, a rainwater garden, a rainwater storage pond, a rainwater pond and the like. Land cover generalization: generalizing and setting sponge facilities such as permeable pavement, green roof, rainwater recycling pool, permeable pavement and the like. Meanwhile, based on the parameters of the drainage system, the drainage subareas and the drainage pipe network data are generalized and set.
And constructing general characteristic simulation of runoff and confluence under rainfall working conditions by surrounding surface runoff generation and surface confluence and utilizing infiltration type mechanism models such as an SCS (least squares) model, a Green-Ampt (Green-Ampt) model and a Horton model on the basis of the hydrological water conservancy parameters and the historical meteorological parameters so as to obtain the hydrological model.
Based on the water quality parameters and the historical meteorological parameters, a pollutant accumulation model and a scouring model can be constructed according to different land types of industrial areas, commercial areas, residential areas and the like, and the accumulation of surface pollutants, the scouring of the surface pollutants and the cleaning of streets are simulated, so that the construction of the water quality model is realized.
The sponge model is constructed by utilizing different sponge facilities applied in the basic parameters of the sponge, the sponge facilities comprise main typical sponge facilities such as a rainwater flower bed, a concave green land, a permeable pavement, a rainwater pond, a small-sized regulation and storage pond and the like, and the main characteristics of the sponge facilities comprise related information such as type, area, surface layer, soil layer, gravel layer, outlet and the like.
And simulating the waterlogging condition under different rainfall conditions by using the drainage system parameters (mainly based on the drainage system generalization and setting obtained by using the drainage system parameters, the drainage subarea generalization and setting, and the drainage pipe network data generalization and setting) as a basis and by using hydrodynamic methods such as a dynamic wave method and a san xi weinan equation and the like through topology inspection of the pipeline data so as to obtain the waterlogging model.
It can be understood that, among the above parameters, the historical weather parameters may be changeable, and the other parameters have relatively small change degrees, and when the parameters change, the parameters before the change need to be updated by the changed parameters, for example, the target sponge city item changes greatly, so that the basic parameters of the land parcel change, and at this time, LID generalization needs to be performed again by using the changed basic parameters of the land parcel.
Further, the step of obtaining the sponge city assessment model based on the LID model, the sponge model, the hydrological model, the water quality model, and the waterlogging model includes: obtaining the initial assessment model based on the LID model, the sponge model, the hydrological model, the water quality model and the waterlogging model; inputting historical rainwater professional parameters of the target sponge city project into the initial evaluation model to obtain output data, wherein the historical rainwater professional parameters comprise historical rainfall working conditions, historical drainage capacity reappearance period, historical waterlogging prevention design reappearance period and historical rainfall typical year data; determining a comparison result of actual monitoring data corresponding to the historical rainwater professional parameters and the output data; adjusting the historical rainwater professional parameters by using the comparison result to obtain new historical rainwater professional parameters; updating the rain professional parameters by using the new historical rain professional parameters, returning to execute the historical rain professional parameters of the target sponge city project, inputting the initial evaluation model until the comparison result meets the preset condition, and determining the initial evaluation model as the sponge city evaluation model.
It can be understood that the historical rainwater professional parameters are the current time and the previous time, and the historical rainwater professional parameters are the historical time parameters, so that the corresponding actual monitoring data can be monitored by monitoring equipment, the initial evaluation model is trained by using the comparison result of the actual monitoring data and the output data of the initial evaluation model until the comparison result meets the preset condition, and the initial evaluation model at the time is the sponge city evaluation model. Wherein, the preset condition may be that the difference between the actual monitoring data and the output data of the initial evaluation model is smaller than a first preset threshold (the occurrence probability of this situation is higher), or the actual monitoring data is the same as the output data of the initial evaluation model (the occurrence probability of this situation is extremely low), the first preset threshold may be set by the user based on the requirement and the actual evaluation model, and the present invention is not limited,
when the initial evaluation model is not trained, the difference between the corresponding output data and the actual monitoring data is large, the historical rainwater professional parameters need to be adjusted continuously, the new historical rainwater professional parameters and the actual monitoring data are used as training samples, the initial evaluation model is trained continuously until the comparison result meets the preset condition, and the difference between the corresponding output data and the actual monitoring data of the initial evaluation model at the moment is extremely small.
The training process of the initial evaluation model, also referred to as calibration of the model, is used to improve the accuracy of the model output.
Specifically, the historical rainwater professional parameters can be obtained by the following method:
1. adjusting the historical rainfall working condition: according to different geographical positions and climatic environments of different projects, different rainfall conditions in rainy seasons are selected and determined, namely the historical rainfall conditions, such as different months, different rainfall intensities (which can be divided into rainstorm, heavy rain, medium rain, light rain and the like), and different rainfall periods are classified and screened to carry out model operation calibration.
2. Adjustment of historical drainage capacity recurrence period: the historical drainage capacity recurrence periods can be respectively determined according to the drainage capacity recurrence periods of the drainage pipe network of 1 year meeting, 2 years meeting, 3 years meeting and 5 years meeting.
3. Adjustment of historical prevention and control design recurrence period: the model operation rate can be determined according to the designed reproduction periods of the waterlogging prevention and treatment for 20 years, 30 years, 50 years and 100 years respectively.
4. Adjustment of rainfall typical year data: the typical annual data of historical rainfall can be determined by taking years as units, selecting rainfall data of 1 year and running a model.
The initial evaluation model calibrated by the method is the sponge city evaluation model, and the accuracy rate of the sponge city evaluation model is correspondingly improved.
Step S14: and evaluating the output index value by using the planning index value of the target sponge city project to obtain an evaluation result.
It should be noted that, in step S14, the planning index value of the target sponge city project is compared with the output index value to obtain a comparison result, where the comparison result is the evaluation result, and the evaluation result usually shows that the difference between the planning index value and the output index value is not greater than a second preset threshold, and is qualified at this time, or the difference between the planning index value and the output index value is greater than the second preset threshold, and is not qualified at this time. Under different evaluation indexes, the corresponding second preset threshold values are different, and a user can set the corresponding second preset threshold values according to the evaluation indexes based on requirements.
Further, after the step of obtaining the evaluation result, the method further comprises: outputting the output index value and the evaluation result in a graphic and/or text manner
After obtaining the evaluation result, the evaluation result and the index value may be output, and the output form of the evaluation result includes, but is not limited to, text, graphics, and the like.
In other embodiments, an output file interface may also be set, and interface packaging is performed based on the setting of the output file of the evaluation result to form an API file or a WEB service for the display application to interface with.
In other embodiments, the output indexes and the evaluation results are displayed visually in a graphical or indexed display form through a software development technology. Meanwhile, evaluation result suggestions and opinions can be formed based on the evaluation results and serve as reference basis for evaluation of the target sponge city project to be displayed in a visual and data mode.
In some embodiments, after the initial evaluation model is calibrated, obtaining a sponge city evaluation model with higher accuracy, and when actual monitoring data corresponding to the evaluation index does not exist, obtaining an evaluation result by the method of the present invention; and when actual monitoring data corresponding to the evaluation index exist, evaluating the actual monitoring data corresponding to the evaluation index by using the planning index value of the target sponge city project to obtain an evaluation result, namely directly comparing the actual monitoring data with the planning index value.
It can be understood that, if the evaluation index can be obtained and the corresponding actual monitoring data is obtained, the evaluation mode may be selected: the method of the invention can be used for obtaining the evaluation result, or directly comparing the actual monitoring data with the planning index value to obtain the evaluation result.
The technical scheme of the invention provides an evaluation method of a sponge city project, which is used for terminal equipment and is used for obtaining evaluation indexes aiming at a target sponge city project; acquiring target rainwater professional parameters of the target sponge city project; outputting and setting the sponge city evaluation model by using the evaluation index to obtain a set sponge city evaluation model; inputting the target rainwater professional parameters into the set sponge city evaluation model to obtain output index values; and evaluating the output index value by using the planning index value of the target sponge city project to obtain an evaluation result.
In the existing evaluation method, an expert needs to carry out on-site investigation on a target sponge city project, and the sponge city project is evaluated through the observed condition and by combining a planning file, the experience of the expert and the like, so that the evaluation time is consumed, and the evaluation efficiency is low.
