江苏淮河流域工业点源负荷空间分布特征研究

搞清流域工业点源的空间分异特征，可为水环境整治与工业规划提供参考依据。采用工业污染源普查数据建立污染源信息数据库，在GIS技术、密度分析法与ESDA方法支撑下，探析江苏淮河流域工业点源与工业污染负荷空间格局与特征。结果显示：工业点源集聚于城市、县城及专业乡镇，污染行业地域分异现象显著，其中，河流、港口及临湖地区成为高负荷工业点源集聚地区，化工、造纸、化纤与医药等行业的工业集中于临海、临河及临湖地区，饮料制造业、副食品加工业点源集中于工业化水平较低的北部流域的少数乡镇，工业氨氮多数来自化工业。在不同工业化水平下，工业污染负荷空间差异大，南部流域负荷整体水平高于北部，北部流域高负荷区分布于少数乡镇与城区

SPATIAL DISTRIBUTION FEATURE OF INDUSTRIAL POINT SOURCE IN JIANGSU HUAIHE RIVER BASIN

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
