摘　　要：采用武汉市1991-2000年人均GDP与水质指标平均值的原始观测数据,分析两者间的相关关系,建立三次回归模型。结果表明:汉江武汉段水质指标随人均GDP变化表现较弱的环境库兹涅茨曲线特征;东湖水质指标随人均GDP变化表现为环境库兹涅茨曲线特征左侧特征。针对汉江武汉段与东湖水质存在的问题,提出了相应的改善措施。In the light of the economic （GDP） increase and water quality data in Wuhan city during 1991 -2000, the Cubic model based on the discharge amount of water quality indexes and per capita GDP was established and the relationship between them was analyzed . The result showed that the characteristics of EKC between per capita GDP and the indexes of water quality of Hanjiang （the area in Wuhan city） showed weaker change, and the characteristic of EKC of Donghu was in the left of curve. Therefore, in viow of the above problem , the ameliorative measures were produced at the end of the paper.
