摘　　要：基于探索性空间分析(ESDA)方法和重心迁移模型研究2006-2017年"中四角"工业废水排放的时空格局演变及其重心迁移轨迹。研究结果表明:2006-2017年"中四角"工业废水排放整体呈下降趋势,并存在明显空间分异特征,呈西南从高到低、中东从低到高的演变规律;总体空间内无明显的空间集聚特征,但局部空间存在明显的集聚特征且以低高集聚状态为主;2006-2017年间"中四角"工业废水排放重心主要在东经114.38°E^114.95°E、北纬29.18°N^29.34°N区域内移动,总体向东北方向移动,移动总距离为107.88 km;"中四角"工业总产值重心总体向西北方向移动,移动总距离为94.39 km,除2011和2012年外其他年份的重心移动距离变化较小。2006-2017年间"中四角"工业总产值重心逐渐偏离几何中心,而工业废水排放重心逐渐向几何中心靠拢且移动速度明显高于工业总产值重心移动速度。This paper analyzed the spatial-temporal pattern evolution of industrial wastewater discharge and its barycenter migration in"Four-city Area in Middle China"from 2006 to 2017,based on Exploratory Spatial Data Analysis(ESDA)method and barycenter migration model.The results showed that the industrial wastewater discharge in"Four-city Area in Middle China"decreased in the studied period,and had obvious spatial differentiation characteristics.Moreover,it showed an evolution law from high to low in the Southwest and from low to high in the Middle East.There was no obvious spatial agglomeration feature in the overall space,but an obvious agglomeration feature in certain local places with low agglomeration in the center and high agglomeration in the surrounding cities.The barycenter of industrial wastewater discharge in"Four-city Area in Middle China"from 2006 to 2017 moved only in the region of114.38°E-114.95°E east longitude and 29.18°N-29.34°N latitude,and generally moved in the northeast direction,with a total distance of 107.88 km.The barycenter of gross value of industrial output in"Four-city Area in Middle China"generally moved to the northwest,with a total moving distance of94.39 km,and the moving distance of the barycenter changed little except for 2011 and 2012.From2006 to 2017,the barycenter of gross value of industrial output in"Four-city Area in Middle China"gradually deviated from the geometric center,while the barycenter centers of industrial wastewater discharge gradually converged to the geometric center,and its moving speed was significantly higher than that of the barycenter of gross value of industrial output.
