摘　　要：根据观测井地下水实测数据,对位于准噶尔盆地西北缘的克拉玛依农业综合开发区地下水埋深时空变化及其驱动因素进行分析。结果表明:①1997-2009年,该区地下水位呈持续上升趋势,农业综合开发区地下水位上升与灌溉期有着直接的关系;②空间分布呈现沿开发区主干道(蓝天大道)两翼,地下水位向西北缘和东北缘逐渐抬升,形成水位抬升中心,并且随着抬升中心数量增多、面积扩大而连成一片;③降雨量和气温对开发区地下水埋深影响不大,灌溉量增加和灌溉水回归是导致地下水位变化的主要原因。为控制地下水位上升,防治土壤次生盐渍化,促进新垦绿洲农业可持续发展,应大力发展节水灌溉技术,并制定科学合理的灌溉定额。Based on the measured data of groundwater level from the observation wells,this paper analyzes the temporal and spatial characteristics and affecting factors of groundwater level change in Karamay agricultural development region in the Junggar Basin.The results show that groundwater level in the study area was continuously raised during the period of 1997-2009.There was a direct relationship between the raise of groundwater level and the irrigation period in the study area.Groundwater depth was gradually raised from the northwestern marginal zone to the northeastern marginal zone of the basin.As a result,many centers with high groundwater level were formed.As the increase of both the number and extent of the centers of groundwater level raise,these areas may be connected.The effect of precipitation and temperature change on the dynamic change of groundwater depth was not significant,and it is considered that the increase of irrigation volume and recycled water were the main factors resulting in groundwater level raise.In order to control groundwater level,prevent soil salinization and promote sustainable development in the agriculture development region,it is essential to develop water-saving irrigation technique and work out a rational irrigation quota.
