东江流域枯水期调度水环境效果分析及评价

Analysis and Evaluation ofWater Environment Effect of Dongjiang River Basin Regulation in Dry Season

从东江流域枯水期水资源调度水环境监测工作成果入手,分析了东江水资源调度的水质现状,对东江中上游龙川—博罗河段主要污染源,选择氨氮作为主要污染因子,对实施调水前后历史同期水质状况变化趋势进行重点分析,认为枯水期调水对改善东江中下游枯水期水质状况有显著效果,并提出进一步改善枯水期水量调度水环境效果的建议。

Based on the monitoring results of water environment for water resources regulation in Dongjiang river basin in dry season,this paper analyzes the water quality status of water resources regulation in Dongjiang river basin,selects ammonia nitrogen as the main pollution source of Longchuan-Boluo reach in the middle and upper reaches of Dongjiang river,and focuses on the analysis of water quality change trend in the same period before and after the implementation of water diversion.It is considered that water diversion in dry season can improve the water quality of the middle and lower reaches of Dongjiang river.In addition,suggestions are put forward to further improve the water environment effect of water regulation in dry season.
