Abstract: This paper, based on economy and water pollution data of Jiangsu from 2007-2014, uses Moran’s indicators and LMDI indicators and LISA graphs to divide economy factors of water pollution into size, structure, scientific consumption, and technical pollution effects, and studies the temporal spatial features of Jiangsu’s water pollution. GDP shows positive relation to gross water pollution spatially, with a rise and fall from 2007 to 2014. Temporally, Changes in size and scientific consumption effects increase the water pollution effect, but the structure and technical pollution effects do on the contrary. Spatially, size and scientific consumption effects have a low value concentrating, but the structure effect does not. Technical pollution effect has both high value concentrating and high-low value concentrating. Jiangsu’s water pollution is mainly concentrating in 119.6359°-119.6892°E, 32.1038°-32.2075°N region, transferring northward, and moving selectively east-westward. 

摘要： 基于2007—2014年江苏省各地区的经济与水污染数据，运用全局Moran’s I 指数、LMDI指数及LISA聚集图，将水污染的经济驱动因素分解为规模效应、结构效应、科技消费效应及技术污染效应，探究江苏省水污染的时空变动特征。结果表明，GDP与水污染总量在空间上呈正相关关系，2007—2014年相关性先增后减。在时间维度上，规模效应及科技消费效应的变化增加了江苏省各地区的水污染效应，结构效应及技术污染效应的变化则减少了水污染效应；在空间维度上，规模效应及科技消费效应存在低值聚集效应，结构效应不存在显著的空间聚集效应，技术污染效应存在高值聚集效应及高低值聚集效应；江苏省水污染重心为119.6395°E—119.6892°E，32.1038°N—32.2075°N的区域，水污染重心自南向北转移，在东西方向上选择性移动。
