从“十一五”期间河南省各地区主要污染物排放的实际情况来看，各地区降污减排效果差距明显，环境污染的区域差异问题越来越成为影响河南省和谐社会建设和工业化进程的重要障碍。主要选取了极差、加权变异系数和锡尔熵3个指标，对河南省2006—2009年间的主要污染物排放情况进行了地区差异度分析，旨在为政府制定更加合理的节能指标和部署减排任务提供科学的决策参考。

From the actual situation of major pollutants emissions, there are obvious gaps in regional pollution abatement and emission reduction effect during the“11th Fiveyear” in Henan Province, and the regional differences problems of environmental pollution is increasingly becoming a big obstacle to harmonious society construction and the industrialization development of Henan Province. Therefore, this paper selected three indicators of range, the weighted coefficient of variation and Theil entropy, analyzed regional differences of major pollutants from 2006 to 2009 in Henan Province, which would provide some scientific suggestions for government to make pollution abatement measures and allocate the task of reducing emission.
