摘  要：
灰水足迹是可以量化水污染的指标,在计算山东省灰水足迹和分析水质污染程度的基础上,基于ESDA研究各市灰水足迹强度的全局、局部空间自相关性,构建灰水足迹强度的空间集聚图,衡量经济增长下的水环境负效应。研究表明:2001-2014年山东省各市的灰水足迹总体上呈现下降趋势,水污染压力逐年降低;山东省各市灰水足迹承载指数偏大,说明水质污染严重,并且区域间的污染程度差异大;山东省各市的灰水足迹强度不断下降,说明经济发展对水污染的影响减小,水环境负效应减轻;山东省灰水足迹强度具有不断增强的全局自相关性,各个市出现集聚现象,不同地市的集聚分布也日益明显;山东省西部地区稳定属于高高集聚,低低集聚主要分布在东部地区,并不断向外扩展。研究结果为政府部门评价水污染状况、制定有关水污染控制和水生态文明防护的政策提供依据。

摘  要：
Gray water footprint is a quantified indicator for water pollution. The paper calculates the gray water footprint and analyzes the degree of water quality pollution in Shandong Province. The ESDA model is applied to study the global and local spatial autocorrelation of the gray water footprint intensity. The spatial concentration maps about the grey footprint intensity are built and the negative effects of water environment under the economic growth are measured. The results indicate that during 2001-2014,in Shandong province,municipal grey water footprint shows a trend of decline and the water pollution pressure reduces year by year; cities in Shandong province of grey water footprint load coefficient are too large,indicating that the water pollution is serious,and the difference of regional pollution degree is large; The grey water footprint intensity has a decreasing tendency in cities which means that the influence of the economic development on water pollution has decreased and the negative effects of water environment has been alleviated; The grey water footprint intensity in Shandong province has rising global spatial autocorrelation,which means that there exists a spatial cluster feature and the spatial cluster feature among different cities has become more and more obvious. The regions with HH correlation pattern are mainly located in the west of Shandong province,while the regions with LL correlation pattern are mainly located in the eastern of Shandong province and have an obvious diffusing tendency. The study results provide the reference for the government departments to evaluate the water pollution status and decide the policies of controlling water pollution and protecting water ecological civilization.
