| 摘 要： | 根据2005年中国31个省、市的水污染物处理情况、水资源和人均地区生产总值的统计数据,分析区域间的差异。结果表明:目前中国区域水环境压力和水污染防治能力与经济水平都呈现显著空间线性正相关,而水环境压力与水污染防治能力的空间线性相关性不显著,根据不同区域水环境压力和水污染防治能力的关系,按照加强水污染防治能力的紧迫程度,从大到小分为Ⅰ、Ⅱ、Ⅲ、Ⅳ四级区域,分别对不同区域进行了现状分析和对策建议。

| Abstract: | Based on statistics of water pollution,water resource and per capita gross regional product from 31 provinces of China in 2005,regional diversity was analyzed.Results showed that water environment pressure and capability of water pollution control have spatial positive correlation significantly with level of economics,but spatial correlation between water environment pressure and capability of water pollution control is not significant.According to relationship of water environment pressure and capability of water pollution control,criticality of capability of water pollution control was divided into 4 grades from I to IV,and the status in different grad districts were analyzed and countermeasures were also suggested. |

| Keywords: | water environment pressure capability of water pollution control correlation analysis classification analysis |
