中文摘要	绿洲是干旱区人类活动的载体,水是绿洲存在和发展的核心,干旱区绿洲规模及可持续性问题与水密切相关。本文以中国西北干旱区的塔里木河流域为研究对象,依据水热平衡原理,建立绿洲适宜规模数学模型,结合现状气象水文资料,测算绿洲适宜发展规模。结果表明:(1)在自然因素和人为因素的综合作用下,绿洲一直处于时空演变的过程;(2)水资源的消长变化是影响绿洲时空演变的直接驱动力;(3)水资源是制约绿洲发展规模的根本原因,在塔里木河流域水资源供给现状下,可利用水资源量已达到所能维系的最大绿洲规模,耕地面积不宜再扩大。最后,结合对塔里木河流域水土资源开发和绿洲发展存在的问题,提出在干旱区绿洲农业发展过程中,要着力发展绿洲节水产业,大力推广节水技术,改进灌溉方式,加快径流调节工程建设,实现地表水和地下水联合调度和管理,提高水资源利用率。为干旱区绿洲可持续管理提供科学参考依据。
英文摘要	Water is the core of the development and existence of oasis, which is itself the carrier of arid human activities. Therefore, scale and sustainability issues of oasis are closely related with the availability of water in arid regions. This paper examined the Tarim River Basin (TRB) in the arid northwest China as a case study. Based on principles of water and heat balance, a mathematical model for suitable scales of oases was established. The model was used to calculate oasis suitable scale by combining with current hydro-meteorological data. The results indicated that: 1) Because of comprehensive impacts of natural and human factors, oases were still in the process of evolution in time and space. 2) Changes in water resources were the direct driving factors of oasis evolution in both time and space. 3) Water resources were the root restrictive factors of oasis development. With the current water resources supply, available water resources had reached the limit of sustaining the largest oasis scale, and the current cultivated land areas were especially unfavorable to expand for the current oasis scale. Finally, sustainable control measures for stable oasis (e.g., development of water-saving industries, improved irrigation modes, regulated runoff engineering and increased groundwater resources utilization) were put forward. These measures were expected to provide the scientific basis for sustainable management of oasis in arid regions.
