摘要
利用综合营养指数评价方法对重庆市城区12个饮用水源地进行了水质调查和富营养化评价。结果表明，饮用水源污染主要表现为营养盐和有机物污染，CODMn范围在1．79～8．13mg／L；TN范围在0．778～4．12mg／L；TP范围在0．013～0．067mg／L；Chla范围在2．99-212mg／m^3。评价认为，已建成使用的6座水库均达到富营养化水平；拟建6座水库中，2座达轻度富营养化，其余水库达中营养。水体污染来源主要为面源污染。
The eutrophic state and water quality of 12 drinking water resources were evaluated by using the comprehensive nutritive index. The results show that the drinking water resources is polluted by nutritive salts and organic materials, and the values of CODMn ,TN,TP and Chla were 1.79-8.13 mg/L, 0. 778-4.12 mg/L, 0. 013-0. 067 mg/L and 2.99-212 mg/m^3 respectively. The water quality of 6 built reservoirs is up to eutrophic level and the water quality of 2 building reservoirs and 4 building reservoirs is the slight eutrophic level and middle eutrophic level separatively. The water quality is mainly polluted by chemical fertilizer, poultry and animal culture, and aquatic culture.
