摘　　要：选取松辽平原典型地下水监测站点,收集2005—2014年地下水埋深月尺度数据资料,并从松辽流域水资源公报中获取降水、农田灌溉用水、地下水开采等数据。基于M-K趋势分析、相关性分析和贡献率分析的方法研究了松辽平原地下水埋深年内、年际变化特征,并识别出研究区地下水埋深变化的关键影响因子。结果表明:(1)松辽平原农业用水量占总用水量的74%,农业用水的增加导致松辽平原用水总量显著增长;(2)松辽平原的3个亚平原区中,松嫩平原地下水埋深呈现出显著的减小趋势,而三江平原与辽河平原的地下水埋深呈现出增长趋势;(3)GDP、工业用水是辽河平原地下水埋深变化的关键影响因子,而对于松嫩平原和三江平原,农田灌溉用水、地下水开采是影响地下水埋深变化的关键因子。In this paper,typical groundwater monitoring stations in Songliao Plain were selected to collect monthly scale data of groundwater depth from 2005 to 2014,and the data of precipitation,farmland irrigation and groundwater exploitation were obtained from the water resources bulletin of Songliao Basin.Based on the M-K trend analysis,correlation analysis and contribution rate analysis,the annual and inter-annual variation characteristics of groundwater depth in Songliao Plain were studied,and the key influencing factors of groundwater depth variation in the study area were identified.The results are as follows.Firstly,the agricultural water consumption accounts for 74%of the total water consumption in Songliao Plain,and the increase of agricultural water consumption has led to a significant increase in the total water consumption of Songliao Plain.Secondly,among the three sub-plain areas of Songliao Plain,the groundwater depth of Songnen Plain has shown a significant decreasing trend,while the groundwater depth of Sanjiang Plain and Liaohe Plain has shown an increasing trend.Thirdly,GDP and industrial water are the key influencing factors of groundwater depth change in Liaohe Plain,while for Songnen Plain and Sanjiang Plain,irrigation water and groundwater exploitation are the key influencing factors.
