中文摘要	[目的]估测地下水资源变化动态并对其安全性进行识别,为策勒绿洲水资源管理及维护绿洲生态安全提供一定决策依据。[方法]分析策勒绿洲总用水需求,基于策勒河径流与地下水动态监测数据,计算绿洲用水缺口;最后,通过绿洲长期地下水位监测资料分析地下水位随时间变化规律。[结果]综合考虑生态用水背景下,策勒绿洲年均用水缺口5.20* 10~6~1.15*10~7 m~3,当利用策勒绿洲地下水补足绿洲用水差额时,地下水平均埋深年均下降0.27~0.60 m,在非枯水年状态下策勒绿洲地下水补给相对充足使得地下水平均水位无明显变化,只在地下水水位时空分布上有所改变,如20082014年绿洲地下水平均埋深虽有较大幅度波动,但基本维持在21 m上下。[结论]短期来看策勒绿洲地下水埋深变化处于安全范围内,但为了保证绿洲健康可持续发展,并维持地下水埋深的稳定,当前应投入财力到水资源使用的监督和管理中去,将建设农业节水设施作为长期发展策略。
英文摘要	[Objective] Estimating the dynamic changes of groundwater resource changes and identifying possible safety measures, we aim to provide decision basis of managing available water resources and maintaining the ecological security of oasis. [Methods] Firstly, the total water demand of Cele Oasis was analyzed, and then the deficiency of water in oasis was calculated according to monitoring data on river and groundwater dynamics. Finally, the dynamic changes in groundwater level were analyzed using long-term monitoring data of groundwater. [Results] Results revealed that when considering the ecological water use, the average annual water gap in the Cele Oasis was 5.2010~6~1.1510~7 m~3. On average, the annual decline in groundwater depth was varying from 0.27 m to 0.60 m due to continuous use of groundwater in Cele Oasis. During high flow years, the groundwater recharge was relatively abundant that did not make any obvious change in average depth of groundwater level except in its spatial distribution. During 20082014,the groundwater average depth showed more substantial fluctuations, but it basically maintained at the level of 21 m depth.[Conclusion] The change in groundwater depth in Cele Oasis is within safe range. But, in order to ensure healthy and sustainable development of the oasis,and to maintain the stability of groundwater depth, the current financial resources should be invested in water resources supervision and management. Besides, the construction of agricultural water-saving facilities should be viewed as a long-term development strategy.
