格尔木流域地下水水位对气候变化和人类活动的响应

为有效治理格尔木地区地下水水位的上升, 促进地下水资源的科学利用, 减少地下水位上升对生产生活的影响,对气候变化和人类活动影响下格尔木地区地下水位的响应进行研究, 对格尔木冲洪积扇 30年来降水量、 地表径流量、地下水埋深以及格尔木河人类活动进行了逐步回归分析, 结果表明: 近 30 年来, 气候变化和人类活动共同影响着地下水系统, 致使格尔木地区地下水水位发生了明显变化, 地下水水位呈现逐步升高的趋势, 通过逐步回归分析, 格尔木河径流量是近年来引起格尔木地区地下水水位升高的主要因素, 径流量对地下水水位影响较为显著, 显著水平为 0 1 038。

Response of groundwater to climate change and human activities in Golmud Basin

In order to effective g overnance of the rise of groundwater level in Golmud area, Promote the scientific use of groundwater resources,reduce the impact of the rise of the water level on the production and life, In this paper, the response of the groundwater level in the Golmud re2gion is studied under the influence of climate change and human activities, about 30 years of precipitation, surface runoff, groundwater burieddepth and the Golmud River human activities have been analysed through stepwise regression analysis, T he results show: In the last 30 years,Climate change and human activities affect the groundwater sy stem, T he groundwater level in Golmud area has changed obviously, T he ground2water level is gradually increasing, through Stepwise regression analysis, Golmud river runoff is the main factor that causes the rise of groundwa2ter level in Golmud area in recent years, The influence of runoff on groundwater level is remarkable, and the significant level is 0 1 038.
