2010年浙江省管网末梢水水质空间分析

目的进一步了解浙江省集中式供水管网末梢水水质状况，为政府制定有关饮用水政策提供依据。方法收集2010年浙江省集中式供水管网末梢水水质卫生监测数据和浙江省县界电子地图．应用变异函数拟合、kfiging插值预测分析、Getis系数空间分析技术分析浙江省管网末梢水水质情况。结果生成管网末梢水合格率地区分布图，三维趋势分析图，变异函数拟合、kfiging插值预测分析、Getis系数等分析结果。结论直观展示了浙江省管网末梢水水质的地理分布，管网末梢水合格率呈现局部高聚集区的在浙西南，松阳县、江山市、龙泉市、龙游县、衢州市区、云和县、遂昌县，呈现局部低聚集区的在浙东南沿海，瑞安市、平阳县、苍南县、温州市区。

Spatial analysis on the terminal tap water quality in Zhejiang province in 2010

Objective The results of this paper showed the quality of the terminal tap water in Zhejiang Province,and provided a theoretical basis for the government to develop drinking water policy.Methods The terminal tap water quality monitoring data of Zhejiang Province in 2010,and the electronic map were collected.The spatial analysis of semivariogram function,Kriging interpolation,Getis coefficient analysis was used to analyze the terminal tap water quality in Zhejiang Province.Results The area maps of terminal tap water quality,the results of three-dimensional trend analysis semivariogram function,Kriging interpolation,Getis coefficient analysis were produced.Conclusion This paper showed graphically the geographical distribution of terminal tap wate quality in Zhejiang Province by spatial analysis.Regions with higher water qualification rates cluster were located in the southwest of Zhejiang,near Songyang,Jiangshan,Longquan,Longyou,Yunhe,Suichang County and Quzhou downtown,while regions with lower rates in the southeast coast of Zhejiang,near Ruian,Pingyang,Cangnan County and Wenzhou downtown.
