浏阳河长沙市区段水体氮、磷现状监测与评价

浏阳河长沙市区段水体氮、磷现状监测与评价(10000字)
摘  要：水质监测与评价是国家环境保护的一项基础性工作，是贯彻我国“预防为主、防治结合、综合治理”环境管理原则的具体体现。近年来随着长沙市经济的飞速发展，对周围水体的污染也日趋严重，作为市内主要河流之一的浏阳河长沙市区段已经不堪重负，因此，研究和解决水质污染问题对于长沙市内水资源的可持续利用以及市内经济的可持续发展来说尤其重要。
本文通过对浏阳河长沙市区段半年内各个时期的中心水面以下1m处的水体进行频率为15天的采样、实验、计算与分析，使用叠加型指数法进行评价，发现该水域的水体富营养化程度较重，并针对这一情况提出了一些相应的治理与改进的措施。

Monitoring and assessment on Water Environment of Liuyang River in Changsha city
Abstract: Water quality monitoring and evaluation is a basic work to state environmental protection Is a concrete embodiment to carry out our country "prevention, prevention &treatment combination and comprehensive treatment" environmental management principles. In recent years, with the rapid economic development of changsha city, the water pollution around has become more and more serious, as one of the main rivers of liuyang river section overtaxed in changsha city,therefore, to research and solve the pollution problem for changsha city water sustainable use of water resources and the sustainable development of the economy is especially important.
This article through to in changsha city liuyang river section half year each time the water in the center 1 m of water for 15 days of frequency sampling, the experiment, calculation and analysis, the use of superposition type evaluation index method, it is found that the eutrophication of water level is relatively heavy, and in view of this situation highlighted some corresponding treatment and improvement measures.
Key words: Liuyang river; Monitoring and evaluation; Water nitrogen, phosphorus
