沧州地区深层地下水位降落漏斗演变特征与形成机理探讨

Discussion on evolution characteristics and formation mechanism of deep groundwater depression cone in Cangzhou region

沧州地区深层地下水降落漏斗已经成为了制约当地经济发展的主要因素。通过对沧州地区第III含水层组地下水水位降落漏斗的形成和发展演化分析,将其划分为4个阶段,分别为直线发展阶段、稳定发展阶段、急剧扩张阶段和逐渐恢复阶段,并对不同阶段内漏斗的形态和演化特征进行了阐述,提出各阶段影响漏斗演变特征的主导因素。同时指出了地下水位降落漏斗的环境响应,提出了应对水危机的合理化建议。

Deep groundwater depression cone in Cangzhou region has become the major factor that constrains local economic development. In this paper, the aquifer group in Cangzhou region is analyzed, ble development stage, rapid expansion stage formation and evolution of groundwater depression cone of No. III which is divided into four stages, that is, development stage, sta- and gradual recovery stage. The shape and evolution characteristics of depression cone in different stage are described and dominant factors which impact evolution characteristics in different stage are proposed. Meanwhile, environmental response by groundwater depression cone is pointed out and rational suggestions against water crisis are proposed.
