咸阳试验区气候变化对地下水影响因素分析

应对气候变化，进行了咸阳试验区地下水位随降水等主要气候因素变化的关系研究。研究表明，地下水位埋深较小、开采量较小时，气候因素变化与地下水位变化的关系密切；地下水位埋深较大、开采量较大时，二者关联性较差。人类长期不断增加地下水开采，是导致试验区地下水位持续下降的主要原因。研究结论可为制定应对气候变化的具体措施提供科学依据。

Analysis on Influencing Factors of Climate Change on Groundwater in Xianyang Test Site

The research on the groundwater level varying with climate factors was carried out in Xianyang test site in order to deal with climate change.The results show that the climate factor change is in close relationship with the groundwater level change when the groundwater burying depth and groundwater exploitation are small,and their relationship is poor when the groundwater burying depth and groundwater exploitation are large.The increase of long-term groundwater exploitation is the main reason for continuous drawdown of the groundwater level at the test site.The conclusion could provide scientific basis to concrete measures formulation for responding climate change.
