摘　　要：以阿克苏河流域为研究对象,采用水热平衡原理构建绿洲耗散型水文模型,结合1960-2010年水文气象数据,分析了阿克苏河流域适宜绿洲规模和适宜耕地面积。结果表明:当前来水条件下,阿克苏河流域天然绿洲适宜规模约为1.37×104km2,人工绿洲适宜规模约为0.41×104km2。阿克苏河流域绿洲长期处于退化的不稳定状态,绿洲实际面积远大于绿洲适宜面积。研究阿克苏河流域绿洲耗水机理对合理配置有限的水土资源,保持绿洲的稳定和可持续发展具有深远意义。Choosing Aksu river basin as the study area,a suitable oasis scale computation model was built based on water-heat balance,and the suitable scale and stability of oasis in Aksu river basin was analyzed by using the hydro-meteorological data during 1960-2010. Under current water inflow condition,the suitable scale of natural oasis is about 1. 37 × 104 km2,and the suitable scale of artificial oasis is approximately 0. 41 × 104 km2 in the Aksu river basin. The oasis of Aksu river basin has been in a state of unstable degeneration for a long time,this is principally because the actual area of the oasis has far exceeded the suitable oasis scale. Therefore,study the water consumption mechanism of the oasis in the Aksu river basin is of great significance to analyze the rational allocation of limited water resources and maintain the stability and sustainable development of the oasis.
