摘要
通过对近10 a汉江生态经济带湖北段水质监测资料进行统计分析,揭示了汉江生态经济带水环境污染的现状及主要问题,结果表明:汉江湖北段干流水质状况总体较好,但发展趋势不容乐观;支流水质趋于好转,部分支流污染依然严重;丹江口库区干流及入库支流水质稳定,但枯水期水质污染突显;汉江下游“水华”频发,出现频次越来越密。在分析了问题产生原因的基础上,提出了保护汉江生态经济带水环境、促进水资源可持续利用的治理对策。
Based on the statistical analysis of water quality monitoring data of the Hanjiang River in the past 10 years,this paper introduces the current situation and main problems of water environment pollution in the Hanjiang River Ecologic Economic Belt.The results show that:(1)In general,the water quality of the mainstream of the Hanjiang River is good,but it develops in the wrong direction.(2)The water quality of tributary tends to be better,but the pollution in some tributaries is still serious.(3)The water quality of the main stream and tributary in the Danjiangkou reservoir area is stable,but the water pollution during the dry season is more serious.(4)The water blooms in the lower reaches of the Hanjiang River occurs more and more frequent.After analyzing the causes of the problems,the measures for protecting the water environment of the Hanjiang River Ecologic Economic Belt and promoting the sustainable utilization of water resources are proposed.
