叶尔羌河下游水电梯级开发对河谷段地下水环境的影响

摘要

本文在叶尔羌河下游水电梯级开发河谷段地质勘察资料的基础上，根据地层岩性、地下水流场、地下水补径排、地下水动态条件，通过建立地下水数学模型，预测水电梯级开发实施后地表水量、地下水水位变化等方面情况，分析评价对河谷段生态环境的影响。%In this paper , groundwater mathematical model is established on the basis of geological survey data of Yarkant River hydropower cascade development valley segment according to lithology , groundwater flow field , groundwater recharge , flow and discharge as well as groundwater dynamic conditions . Conditions in the aspects of surface water amount , groundwater level change and the like after hydropower cascade development and implementation are predicted .The influence on the valley segment ecological environment is analyzed and evaluated .
