| 摘 要： | 以黑河干流中游水资源管理为例,利用地下水数值模型研究了天然和人工活动作用下泉水、地下水向地表水排泄量的变化规律;预测分析了不同情景下的水资源开发利用状况.研究表明,地下水向河-泉的排泄量呈衰减趋势,且地下水的增采量和渠系防渗节约的水量主要来源于地下水储存量的消耗;指出在目前有限的水资源条件下,为保护生态地质环境,必须限制地下水的持续超采.

| Abstract: | Through a case study of water resources management of the middle reaches of Heihe river basin,this paper demonstrates the application of a groundwater numerical simualtion model.The established groundwater flow model could simulate changes of base flow quantities between groundwater and surface water,also of the quantities of springs with time under the affect of natural and human activities.This model is used to analyze different water resources management scenarios.The results demonstrate groundwater discharge to river and spring would decrease continuously,and groundwater exploration increment and seepage loss decrement from proof against channel leakage are mainly balanced from the groundwater storage release.This explaines the measures of limiting the sustained groundwater yield would have to be made for ecology environment protection for present limited water resources. |
