摘要
本文通过综合分析海河平原地下水资源盈余量以及建立典型三级区平原开采系数与地下水水位下降速率、地面沉降速率的关系,分析了各三级区平原依靠环境容量可扩大开采量,根据疏干时限性评价指标对海河平原地下水的开采潜力进行了评价,客观展现了维持现状开采条件下研究区地下水资源可持续利用的暗淡前景。
The surplus of groundwater resources in the Haihe plain is synthetically analyzed in this article,and the relationships between the exploitation coefficient and the speeds of groundwater levels and land subsidence in model area are established. The enlarged withdrawal rate controlled by environmental capacity is also analyzed. Based on above results,evaluation of the exploitation potential of groundwater in the Haihe plain is carried out. The results exhibit a faint foreground for the sustainable utilization of groundwater under the current exploitation conditions in the plain.
