摘　　要：针对沙漠区地下水位变动可能产生的生态响应,以乌兰布和分洪区为例,利用统计学原理分析了2001-2009年地下水埋深动态及其对主要水文气象因素的响应。结果表明:分洪区地下水位年内变化规律受多因素控制,属综合水位动态,且具有季节周期性,灌溉时间和灌溉水量是决定年内变化规律的主导因素;分洪区地下水年内埋深与蒸发在不同季节关系不同,与黄河径流量关系不明显。分洪区地下水位年际变化动态随黄河径流量增大而升高,同时在一定深度内地下水埋深越小,蒸发越大。In view of the ecological response produced by the changes of the groundwater level in the desert area, with Wulanbuhe Flood Diversion Area as an example, the statistical principle is used to analyze the groundwater depth in dynamics from 2001 to 2009 and its response to major hydrometeorological factors, and the results indicate that the annual changing rule of the groundwater level in the flood diversion area is controlled by multiple factors, is a comprehensive dynamic water level, and has seasonal periodicity. Be- sides, the irrigation time and irrigation water is the dominant factor that determinines the annual changing rule. The relationship be- tween the groundwater depth in dynamics and the groundwater evaporation are different in different seasons, and the relationship with the Yellow River runoff is not obvious. However, the yearly groundwater depth in dynamics rises with the increase in the Yellow River runoff, and in some groundwater depth, the evaporation decreases with increasing depth.
