摘要
随着环境污染问题的加重,水生态环境和经济社会发展的关系成为社会关注的焦点.本文以江苏省市内9条河流为研究对象,基于POI数据和主成分分析法探究水质空间分布规律和影响因素,以期给江苏省河流污染治理提供一定的科学参考.结果表明,苏南苏中地区的河流水质较好,苏北地区的河流水质相对较差,河流的中游水质优于上下游.POI数据和水质之间存在一定的相关性,但是受到水体治理程度不均的影响,清水区呈负相关,臭水区呈正相关,最大的相关性POI类型缓冲区半径为1400-1600 m.不同的POI类型对水质的影响半径范围存在明显差异,影响程度最大的是交通设施用地,最小的是公共绿地等开放空间.
Abstract
With the aggravation of environmental pollution,the coordination level between water ecological environ-ment and economic and social development is increasingly becoming a focus of concern in the community.This pa-per,taking 9 rivers in Jiangsu Province as the research object,explores the spatial distribution and influencing fac-tors of water quality to provide scientific reference for planning and river pollution control in Jiangsu Province based on POI data and principal component analysis.The results show that the water quality of rivers in the south and middle areas of Jiangsu is better than that in the north,and the water quality of rivers in the middle reaches is bet-ter than that in the upper and lower reaches.There is a certain correlation between POI data and water quality,but affected by the uneven water treatment degree,there is a negative correlation in clear water area and a positive cor-relation in smelly water area.The maximum correlation POI type buffer radius is 1400-1600 m.The influence ra-dius of different POI types on water quality is obviously different.
