Construction and interactive application method of non-point source phosphorus pollution index model

Abstract

The invention belongs to the technical field of environment protection, and particularly relates to a method for construction and interactive application of non-point source phosphorous pollution index models. The method comprises a step of constructing non-point source phosphorous pollution index models which integrate data conversion, model operation and result visualization and manager-orientedinteractive webpage applications on the basis of an open-source R platform, wherein the models and the applications are used for watershed management decision making. According to the method, the non-point source phosphorous pollution index models which integrate data conversion, model operation and result visualization and the manager-oriented interactive webpage applications are constructed onthe open-source free R platform, and the models and the applications are used for final watershed management decision making, so that the efficiency of model data analysis and decision making is greatly improved and the dynamic interactive application of models is realized.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a construction and interactive application method of a non-point source phosphorus pollution index model. Background technique [0002] Non-point source pollution has caused serious water environmental problems. The quantification of non-point source pollution has become a hot topic in international research today. Model simulation is one of the most direct and effective ways to study non-point source pollution. Establishing a practical non-point source Pollution models have become an effective means to manage and control non-point source pollution. [0003] Based on the advantages of GIS (Geographic Information System, GIS, geographic information system) in storing and processing a large amount of spatial data and realizing the visualization of spatial data, GIS is applied in the research of non-point source pollution. Usually, GIS is combined with t...

AI Technical Summary

Problems solved by technology

However, the secondary development of the complete integration of the non-point source pollution model and GIS needs to start from the bottom layer of the system, and a lot of software development and programming work is required. The development cost is high and requires the participation and cooperation of multiple professional developers, and the product software is expensive. high cost

[0007] In view of the fact that most of the non-point source pollution models in the prior art are loosely combined with GIS, the powerful functions of GIS such as spatial analysis have not been well applied, the fully integrated secondary development process is highly dependent on GIS professionals, and the price of mature software products Expensive and other problems, there is an urgent need for a non-point source pollution index model with low construction cost, which can integrate data conversion, model operation and result visualization expression, and an interactive application method that can be oriented to managers for the final watershed management decision making
