依据地下水资源与城市的组合特征,将海河流域平原区的城市划分为山前平原、中部平原和滨海平原三种类型。选择其中的典型城市石家庄市、唐山市、衡水市、沧州市、天津市为研究对象,运用压力-状态-响应概念模型,对各个城市地下水资源的持续利用问题进行深入分析。结果表明,所选城市普遍存在地下水资源压力过大,地下水资源系统状态紊乱,自然环境对地下水系统的响应日趋成灾,人为控制措施少而不力的特点。
According to the characteristics of the combination of groundwater resources and cities, the cities in the plain area of the Haihe River Basin are divided into three types: the plain before the plains, the middle plain and the coastal plain. Shijiazhuang city, Tangshan city, Hengshui city, Cangzhou city and Tianjin city are chosen as the research objects, and the concept of pressure-state-response is used to analyze the sustainable utilization of groundwater resources in various cities. The results show that the prevalence of underground water resources in the selected cities is too high, the groundwater resources are in a disorderly state, the natural environment is becoming increasingly disastrous to the groundwater system, and human control measures are less and less effective.
