摘要
针对铁岭市2011年饮用水源地清河水库小流域内水质状况,建立模糊综合评价数学模型,通过分析非点源污染对水质的影响进行水污染风险综合评价。目的是定量分析评价清河水库水环境质量现状和存在的问题。计算结果表明:清河水库小流域水质较差,水库入口、红花甸、聂家沟、曾家屯、腰堡的水质均属于V类水,说明水库水质已受到严重污染,而非点源污染是造成水库水质污染和波动性变化的主要原因和影响因素,急需进行科学的治理,否则将带来严重的环境、经济和社会损失。
A mathematical model of fuzzy comprehensive evaluation was established in this study. Through the analysis of the impact of non point source pollution on water quality, we can reveal the water quality situation of drinking water sources in 2001 and also can forecast the pollution risk of the Qinghe Reservoir Small Watershed. So we can definite the quantitative anal ysis of current situation of water quality and evaluate the existing problems of water environment for the Qinghe Reservoir. The results showed that the Qinghe Reservoir watershed water quality was worse, especially at the entrance of Reservoir, Hong huadian, Niejiagou, Zengjiatun and Yaobao, the water quality of the above areas was of category V, the reservoir's water has been seriously polluted, and non-point source pollution is the main reason. Those are the impact factors that caused water pol lution and volatility changes of the reservoir. So it needs scientific governance urgently, otherwise it will bring about serious environmental, economic and social losses.
