摘　　要：在我国东部高潜水位地区,长期的地下煤炭开采造成地表形成大面积的沉陷水域,受周围人类活动的影响,沉陷水域水环境污染风险逐渐增大。以淮南潘集采煤沉陷水域为研究对象,根据韦伯–费希纳定律,选取与沉陷水域水环境关系密切的水质评价指标,分析不同时间段沉陷水域的水环境状况,通过图层叠加融合定量反映沉陷水域水环境质量时空变化及潜在水环境风险的发生时间和区域。研究结果显示,沉陷水域水质不容乐观,存在水质恶化的风险。从5月到11月,随着时间的变化,沉陷水域都呈现出中警以上的警情,在不同月份沉陷水域出现的警情区域也有所不同,其中沉陷水域的西部和中部警情出现的概率较大。在今后的水环境管理中需针对不同时间不同区域采取针对性的治理措施,避免水环境污染风险的发生。In area with high groundwater level in the east of China,long-time underground coal mining results in a large subsidence water area on the surface.The risk of water environment pollution in subsidence waters is increasing gradually with the influence of human activities.According to Weber-Fisher law,this paper took Panji waterlogged area of Huainan as the research object,selected the water quality evaluation indexes closely related to the water environment of the waterlogged area,analyzed the water environmental conditions of the waterlogged area in different periods,and quantitatively reflected the time and the area of the water environment quality change and potential water environment risk of the waterlogged area through the overlay and fusion of layers.The results show that the water quality of waterlogged area is not optimistic,and there is a risk of water quality deterioration.The waterlogged area presents warning conditions above middle level with the change of time from May to November.The warning areas changes in different months.Among them,the western and central part of the waterlogged area has a higher probability of occurrence of warning situation.In the future water environment management,it is needed to take targeted preventive measures for different areas during different periods to avoid the risk of water environment pollution.
