摘要
采用中国环境监测总站推荐方法,对重庆市36座大中型水库富营养化进行了调查和评价,结果为36座水库中达到富营养的有17座,占调查水库的47.22%(中度富营养占11.11%、轻度富营养占36.11%);达中营养的有15座,占调查水库的41.67%;贫营养水库3座,占调查水库的8.33%,表明重庆水库富营养化严重。作为城镇集中饮用水源地的27座水库达富营养化的有14座,占51.85%;中营养水库11座,占40.74%;贫营养水库2座,表明重庆市饮用水源水质受富营养化影响严重。分析了水体富营养化产生的原因,并提出了相应对策。
Investigation of 36 reservoirs with a capacity of 〉 10 000 000 m3 in Chongqing has revealed serious eutrophication of these water bodies. Seventeen reservoirs are eutrophers, 15 are mesotrophers and 3 are oligitrophers. Of the 27 reservoirs which are the major sources of the drinking water for the urban dwellers, 14 are eutrophers, 11 are mesotrophers and only 2 are oligotrophers. The causes for the eutrophication of the water bodies are analyzed and policy recommendations are made.
