汤溪水库水质现状及污染源分析

Present Situation of Water Quality and Pollution Source Analysis in Tangxi Reservoir

指出了汤溪水库是粤东最大的水库,也是饶平县居民和工农业用水重要水源,但近年来年水库水质不断恶化,水体呈富营养化。通过对水库及其支流的水质进行采样分析,运用单因子评价法、营养状态指数法、藻类丰度指数法等方法对水库水质现状进行了评价分析。结果表明:汤溪水库的污染源主要是生活污染、农业面源污染和禽畜养殖污染。部分段面水质已达劣V类,应尽快治理。

Tangxi Reservoir is the largest reservoir in Province. It is an important water sourcefor industrial and agri- cultural use in Raoping county. However, in recent years, the water quality of the reservoir is deteriorating and the water body is eutrophic. In this paper, the water quality of the reservoir and its tributaries is sampled and analyzed, and the water quality status of the reservoir is evaluated by single factor evaluation method, nutrition status index method and algal abundance index analysis. According to the results of field investigation, this paper gave a brief a- nalysis of the Tangxi reservoir pollution sources.
