摘　　要：以安徽淮南顾桥采煤沉陷积水区水体为研究对象,利用综合水质标识指数法进行综合水质评价和综合营养状态指数法进行水质富营养化状况评价,结果表明:分析样本中64%达到Ⅱ类或Ⅲ类水质,水质总体较好;该沉陷积水区总体不存在重金属污染,有机物指标对该区域水体污染贡献率较大;该沉陷积水区富营养化状况不容乐观,应加强重视;超标采样点及重度富营养化采样点多集中在村庄相对密集的南部沉陷区域;农村面源污染是该积水区富营养化的主要来源。Anhui Huainan Guqiao mining subsidence seeper area is researched in the paper, and comprehen- sive water quality identification index method is used to assess water quality, while comprehensive nutrition state index method is used to evaluate the eutrophication condition of water quality, the results show that 64% of water samples are Ⅱ class or Ⅲ water quality, the water quality is good. There is no heavy metal pollution, the organic compounds have larger contribution in regional water pollutions. The subsidence seeper area eu- trophication status is not optimistic and it should be paid more attention to. Comprehensive water quality as- sessment results of sampling points and the severe eutrophication of sample points are more concentrated in southern subsidence area in that village, and the main source of water eutrophication is rural non-point source pollution.
