Embodiment Construction

[0038] Below in conjunction with accompanying drawing and concrete implementation process, the patent of the present invention is described further.

[0039] In order to better illustrate the specific implementation scheme of the patent of the present invention, the application of the method adopted in the present invention in Shanghai Lingang New City is taken as an example to illustrate the implementation process of the content of the present invention.

[0040] Shanghai Lingang New City is located in the southeast corner of Shanghai. 45% of its land area is formed by land reclamation. The soil has high salinity and the growth of transplanted plants is limited. The center of the main urban area of ​​Lingang New City is Dishui Lake, which is the largest in the world. artificial landscape lake with an area of ​​5.56km 2 , and the "Three Ripples" along the lake (Neilian River, Zhonglian River,

[0041] Wailian River) and "Seven Shots" constitute the main structure of the Lingang...

Abstract

The invention relates to a method for analyzing the spatial distribution characteristics of rainfall runoff pollution based on GIS technology, which includes obtaining spatial information data of land areas in the research area; sampling analysis; rainfall runoff pollution detection data preprocessing and database establishment; optimal GIS model construction Steps such as generating a spatial distribution map of rainfall runoff pollution levels. The present invention introduces GIS technology into the analysis of the spatial distribution characteristics of rainfall runoff pollution, reducing errors caused by subjective methods; at the same time, adopts GIS technology to simulate the spatial distribution characteristics of rainfall runoff pollution, and solves the current problem of single assignment mainly based on land use types The output coefficient method leads to the problem of low accuracy of calculation results, and provides scientific guidance for effectively formulating rainfall runoff pollution control strategies, implementing pollution control measures, and developing sponge city construction.

Description

technical field [0001] The invention relates to a method for analyzing the spatial distribution of rainfall runoff pollution, in particular to a method for analyzing the spatial distribution characteristics of rainfall runoff pollution based on GIS technology. Background technique [0002] In the 1970s, developed countries basically controlled point source pollution such as industrial wastewater and domestic sewage, and non-point source pollution has become the main source of natural water pollution. Relevant studies have shown that even if all point source pollution is controlled, good water environment quality cannot be guaranteed. The reason is that rainfall runoff washes away various pollutants on the ground and brings them into natural water bodies. Therefore, studying the spatial distribution characteristics of rainfall runoff pollution has direct guiding significance for formulating rainfall runoff pollution control strategies and implementing pollution control measur...
