中文摘要	阿克苏绿洲是中纬度干旱区典型的绿洲灌溉系统,制定绿洲适宜发展规模、明确适宜耕地面积,可为实现绿洲的生态稳定与可持续管理提供科学依据。以中国西北干旱区的阿克苏河流域为研究对象,基于作物需水量和绿洲适宜面积模型的水热平衡法,借助典型绿洲结构模型,计算了阿克苏绿洲的适宜耕地面积。结果表明:2010-2015年阿克苏灌区的作物需水量高达740.3 mm,较20世纪60年代的539.6 mm增加了37.2%;考虑到山区来水和下泄塔里木河干流的水量要求,阿克苏绿洲的可用水量为42.6*10~8 m~3;阿克苏河流域绿洲已处于不稳定状态,耕地面积超过了水资源承载能力。计算得出绿洲适宜规模为12 430 km~2,与现有水平相当。基于作物需水量和绿洲适宜面积模型的水热平衡算法计算的阿克苏绿洲的适宜耕地面积分别为4 674 km~2和4 211 km~2,需要在当前耕地水平上退耕18%至26%。
英文摘要	The Aksu Oasis in the arid regions of Northwest China is the second largest irrigation area in the midlatitude arid region. Determination of the suitable oasis scale and identification of appropriate cultivated land can provide a scientific basis for the ecological stability and sustainable management of the oasis. In this paper,the suitable scale of the Aksu Oasis is investigated by using the water-heat balance methods based on the crop water requirement and the typical oasis structure model. The results showed that:(1)the crop water requirement in the Aksu Oasis had been as high as 740.3 mm from 2010 to 2015,37.2% more than that in the 1960 s(539.6 mm);(2)taking into account the water resources from mountainous areas and the discharge demand to the main stream of the Tarim River,the available water resources in Aksu Oasis is 42.6*10~8 m~3;(3)the Aksu Oasis was estimated at an unstable state and agricultural acreage had exceeded the carrying capacity of water resources. It is calculated that the current suitable scale of the Aksu Oasis is 12 430 km~2,which is equivalent to the current level. Based on the crop water requirement and the typical oasis structure model,the suitable cultivated land area are calculated to be 4 674 km~2 and 4 211 km~2,respectively. It is suggested to shrink the farmland by 18% to 26% to get a stable and sustainable development of the Aksu Oasis.
