Abstract:

In recent years，industry water environment problems is one of the factors which restricts the sustainable development of society and economy.Studing on spatial differential features of industrial point source can provide reference for water environmental treatment and industrial planning.This research took five cites in the Jiangsu Huaihe River Basin for example，built industrial point source information database，and analyzed spatial distribution and feature of industrial point source and the pollution load based on pollution source survey data in Jiangsu Huaihe River Basin and GIS spatial analysis method and technique.The results show that industrial point sources concentrated on cites,county town and professional town,and regional difference phenomenon of water pollution industry was obvious.Among them, lots of high load sources tended to be near river,sea and great lakes, especially the chemical industry,paper making and chemical fiber industry.Beverage manufacture and foodstuff manufacture preferred to concentrated in low economic town of north Huaihe River Basin.Industrial ammonia nitrogen source mostly came from the chemical industry.In different industrialization level,industry pollution load made great difference.More pollution load in south river basin than that in north,however high load zone distributed in few cities and towns of north river basin.This research displays the spatial relationship between industrialization and water environment concretely.It points out the high load industry point resource and the main industry renovation region, which can help to analyze industry water pollution issues
