中文摘要：
以淮南潘谢矿区2010年沉陷状况为背景,采用2001—2010年水文气象数据,应用构建的分布式＂河道-沉陷区-地下水＂耦合模拟模型对沉陷区水循环状况进行了模拟,并对模拟结果进行了检验。结果表明,河道汇流、水面降水、地下水和产流在沉陷区积水补给中所占比例分别为84.6%、8.8%、3.6%和3.0%,河道下泄、水面蒸发、渗漏和引水在沉陷区积水排泄中所占比例分别为80.6%、8.2%、1.3%和9.9%,沉陷区的自然水循环主要依赖于相连河道,其次为水面降水与蒸发,与地下水关联甚微。
英文摘要：
Ascertaining water supply and drainage routes and water resource conditions can provide technical support in the comprehensive treatment of coal mining subsidence areas. The subsidence conditions in the Huainan Panxie coal mining area in 2010 and the meteorological data from 2001 to 2010 were used to simulate the local water cycle in min- ing subsidence areas in recent years by the distributed ＂river-subsidence depression-groundwater＂ coupling model, and the model has been verified. The results show that river confluence, precipitation, groundwater, and runoff formed 84.6%, 8.8%, 3.6%, and 3.0%, respectively, of the water supply. River discharge, evaporation, seepage, and water diversion constituted 80.6%, 8.2%, 1.3%, and 9.9%, respectively, of the water drainage. River confluence is the primary factor influencing the water cycle, followed by precipitation and evaporation, with groundwater exerting a negligible influence.
