摘　　要：选用北京市平原地区74眼潜水观测井1990～2009年月埋深资料,基于Mann-Kendall法分析地下水埋深趋势及突变情况,分析了埋深的年代际及年内变化规律,并采用多元线性回归方程分析了气候变化和人类活动对地下水动态的影响。结果表明,地下水埋深在2000年前后发生突变,2000年代地下水埋深剧烈增加,且埋深增幅较大的区域较20世纪90年代大面积扩张;大多数地区地下水动态类型为降雨入渗补给—开采型,靠近水域的地区为灌溉入渗—蒸发型;回归方程相关性显著,说明地下水位变化与降水量和超采量有密切联系。Based on the monthly groundwater buried depth data series of 74 monitoring wells m betjmg plalr area cur- ing 1990-2009, decadal, annual and monthly characteristics of groundwater buried depth were investigated and the driving forces were explored. The Mann-Kendall test was used to detect the buried depth^s trend and abrupt change, and the multivariate linear regression function was performed to study the impacts of climatic change and human activities on groundwater dynamic characteristics. The result revealed that the abrupt change of buried depth occurred around 2000 with the buried depth increased intensively during 2000s; the groundwater dynamic type in most areas was rainfall-infil- tration recharge and mining, while areas close to water area had a type o{ irrigation-infiltration recharge and evaporation. Significant correlation of multivariate linear regression indicated that the variation of groundwater level associated closely to precipitation and overdraft.
