| 摘 要： | 在淮南矿区，常年大规模地下煤炭的开采造成地表塌陷，形成了大面积的沉陷水域。选取潘集和顾桥2个不同类型沉陷水域为研究对象，结合同步的地面实测数据和环境卫星数据，利用综合营养指数法对不同时段沉陷水域水质富营养化进行了综合评价。结果表明：沉陷水域水体都已呈现出富营养化状态，不同类型沉陷水域在时间上和空间上存在着明显的差异。从时间上看，沉陷水域5月份的富营养化程度要明显高于11月份。从空间上看，顾桥沉陷水域富营养化程度要明显高于潘集沉陷水域。

| Abstract: | In Huainan coal mining area, long-term large-scale underground coal mining activities have caused severe ground subsidence, formed a large waterlogged area. In this paper, Guqiao and Panji waterlogged areas were chosen for analysis as two main representative types of waterlogged areas:closed and semi-closed. Comprehensive Trophic State Index method was adopted in this research to evaluate the water quality of the waterlogged areas using information from water samples and Hj-1 data. The results show that the waterlogged areas are of eutrophication and spatial-temporal differences of water quality are founded in different types of waterlogged areas. Generally, the trophic status in May is more serious than in November, and the trophic status in Guqiao is more serious than in Panji. |
