20世纪60年代以来,由于驱动地下水资源变化的开采和拦蓄等人类活动日益增强以及连续多年气候干旱等多重作用,海河平原地下水资源日益匮乏和衰减,并引发了严重的环境地质问题,如地面沉降、地下水水位降落漏斗和地裂缝等,生态功能和社会功能也严重削弱。研究区是南水北调的受水区,南水北调客水资源引来前,由于经济发展对水资源的需求,本区地下水 Since the 1960s, groundwater resources in the Haihe River Plain have been increasingly scarce and decayed due to the increasing human activities such as the exploitation and storage of groundwater resources, and the continuous multi-year climate droughts, which have caused serious environmental and geological problems such as land subsidence , Groundwater level dropping funnel and ground fissure, ecological function and social function are seriously weakened. The study area is the water receiving area for the South-to-North Water Diversion Project. Before the water diversion from the South-North Water Diversion Project was initiated, due to the demand for water resources for economic development, groundwater in the area
