摘要
为分析地下水开采对乌苏里江流量的影响,利用地下水流数值模拟模型,模拟分析了不同开采强度下地下水向乌苏里江排泄量的变化。结果表明,2017~2027年,穆兴平原地下水开采量在维持现状和增大开采至11×10^8 m^3/a的条件下,地下水流向基本无变化,在乌苏里江沿岸的地下水变幅基本在±1m以内。现状持续开采条件下,汇入乌苏里江的地表径流量有所减少,但地下水开采量每增加1×10^8 m^3/a,地下水和地表水向乌苏里江的排泄量仅减少0.2×10^8 m^3/a,相对于乌苏里江流量而言可忽略不计。因此,可认为穆兴平原地下水开采对乌苏里江的流量影响不明显。
A numerical simulation model of groundwater flow in the Muling-Xingkai Plain was used to simulate the changes of discharge amount of groundwater to the Wusuli River under different mining intensities for analyzing the impact of groundwater exploitation on the runoff of the Wusulijiang River.The results show the groundwater flow direction will not change,and the variation range of groundwater level along the Wusulijiang River will be within±1 mfrom 2017 to 2027 under the present continuous production and the increasing groundwater exploitation to 11×10^8 m^3/a.However,the surface runoff flowing into the Wusulijiang River will decrease under the present continuous mining.But the discharge of groundwater and surface water flowing into the Wusulijiang River decreases by only 0.2×10^8 m^3/a with the increase of groundwater exploitation by 1×10^8 m^3/a.Then,the decreased volumes of the discharge of groundwater and surface water flowing into Wusulijiang River are much less than the Wusulijiang River runoff.Therefore,it can be concluded that the influence of the groundwater exploitation in the Muling-Xingkai Plain on the runoff of Wusulijiang River is not obvious.
