摘　　要：根据2012年11月至2013年9月的9次监测数据,分析了淮南潘集开放型和封闭型沉陷区地表水与浅层地下水中氮、磷时间分布特征;通过相关性分析揭示了各类水体内氮、磷之间的响应关系和运移特征;通过各形态氮、磷比对研究区水体营养状态进行了限制性分析.结果表明,两类沉陷积水区内氮、磷时间分布存在一定差异,主要影响因素有降雨、周围农业面源输入、外部河流的互相补给等;各类水体内氮、磷之间均存在不同程度的响应,封闭型沉陷区地表水与浅层地下水中氮、磷响应关系更强;两类沉陷积水区均属磷限制性水体.Based on nine sets of monitoring data from November 2012 to September 2013,the temporal distribution characteristics of nitrogen and phosphorus in surface water and shallow underground water of open and closed subsidence area in Panji of Huainan were analyzed. Response relationship and migration characteristics between nitrogen and phosphorus in each water body were revealed through the correlation analysis. The limiting nutrient status was analyzed through the ratio of each form of nitrogen and phosphorus. Results showed there existed certain differences in the time distribution of nitrogen and phosphorus between the two types of subsidence areas. The main influential factors were precipitation,non-point source,recharge and discharge of river,etc. There were different levels of response between nitrogen and phosphorus in all kinds of water bodies,and the response is stronger in the surface water and shallow underground water of the closed subsidence area. These two types of subsidence areas were all phosphorus restricted water.
