中文摘要	【目的】为研究荒漠河岸林生态系统的耗水规律。【方法】本研究选择塔里木河上游流域作为研究区,通过采集不同土层的土壤样品测定其含水量,并量测不同覆盖度的浅层地下水埋深,分析了荒漠河岸林土壤水分、浅层地下水埋深时空变化规律及二者之间关系。【结果】不同覆盖度土壤水分差异显著,覆盖度越高,土壤保墒能力越强,土壤含水量越高;覆盖度越低,土壤水分活跃程度越高;同一覆盖度不同月份土壤含水量随深度的变化趋势大致相同,各覆盖度土壤含水量垂直变化特征总体满足随着土层深度的增加而增大;覆盖度高的各层土壤含水量随时间变化范围小。【结论】各覆盖度由表层到底层土壤含水量变化幅度与覆盖度有关,植被和地下水埋深越深可以有效控制土壤水分变化,而河道侧渗对地下水的补给却具有一个延迟作用。
英文摘要	【Objective】The study of water consumption provides the theory basis for desert riparian forest ecosystem【Method】This study chooses the Tarim River upstream basin as the study area. By collecting soil samples to measure the moisture content of different soil layer, and the measure depth of shallow groundwater under the condition of different coverage,it had analyzed change law of time and space and the relationship of soil moisture,shallow groundwater depth in the desert riparian forest.【Result】In different coverage soil moisture content existed significant difference,the higher the coverage,keeping moisture ability was stronger,soil moisture content was higher. Coverage was lower,the soil water activity was higher. The same coverage change trend of soil moisture content with depth is roughly the same in different months. Each of the coverage the vertical Changes of soil moisture met increases with the increase of soil depth overall. The higher coverage the soil moisture content changing was small with time. The study of water consumption provides the theory basis for desert riparian forest ecosystem. 【Conclusion】The variation of soil moisture content is related to the degree of coverage form from the top to the bottom in every coverage. The depth of vegetation and groundwater can effectively control soil moisture changes. However,the watercourse lateral seepage has a delaying effect on the groundwater recharge.
