| 摘 要： | 探索变化环境下新疆平原区地下水资源量的变化趋势，是识别地下水环境问题、加强地下水资源管理的基础工作。基于水利部门历次水资源调查评价成果、水利统计资料汇编等数据，对1956—2016年新疆平原区地下水资源量变化及其影响因素进行分析，对变化原因进行探讨。结果表明:1956—2016年新疆平原区地下水资源量呈减少趋势，其中地下水天然补给量基本稳定，地表水体转化补给量持续减少；从地下水补给结构分析，渠系渗漏补给量大幅减少，导致地下水资源量减少；河道渗漏补给量增加，抵消了地下水资源量的减幅。平原区灌溉面积扩大导致的农田灌溉耗水量增大是地下水资源量减少的根本原因，人类活动对地下水资源量的影响大于气候变化。

| Abstract: | The exploration of variation trend of ground water resources is basic work to identify groundwater environmental problems and strengthen groundwater resource management. Based on the data of previous evaluation results of water resource survey and water conservancy statistical yearbook from local water conservancy departments, the change of groundwater resources from 1956 to 2016 and its influencing factors were analyzed. In addition, the causes of groundwater resource variation were investigated. The results showed that the amount of groundwater resources declined from 1956 to 2016 in the Xinjiang plain area. The dynamic variation of groundwater recharge was featured with stable natural recharge. Moreover, the surface water conversed recharge had a dramatically shrunk. Analysis from the structure of groundwater recharge showed that the significant decrease in canal seepage resulted in the decrease in groundwater resources, the increase in river seepage offset the decrease of groundwater resources. The increase in irrigation water consumption in plain area, which was led by the expansion of irrigation area, resulted in the decrease in groundwater resources. The impact of human activities on groundwater resources is greater than that of climate change. |
