非稳定边界条件下地下水开采的影响分析

Analysis on Influences of Groundwater Exploitation under the Condition of the Unstable Boundary

对于潜水含水层平面非稳定流,边界的非稳定性集中表现为水力坡度随时间的变化。本文中,非稳定边界主要以河流为研究对象,采用数值模拟的方法,以叶尔羌河流域泽普灌区为例,从水资源转化关系、各水均衡要素的变化趋势等方面进行分析,研究在非稳定边界条件下地下水开采对非稳定边界的影响、影响原因及其区域水资源系统的影响。

For the unsteady plane flows of the phreatic aquifer, the boundary＇s unstable trated on hydraulic slope changed by time. In the paper, the unstable boundary is regarded properties concenas the studied object, using numerical simulation method, taking one of an Irrigation District Zepu in Yierqiang River Basin as an example. It has carried on the discussion from two respects ： transforming relation of water resources, tendency of variation in water balance factor, etc, then study the influence and its factors on adjacent river and water resources system in the region under the condition of groundwater exploitation in the unstable boundary.
