Abstract  

Urbanization is one of the important human activities affecting the oasis ecosystem,so it is essential for the government in the oasis area to choose reasonable urbanization mode. In this article, we took the Wuwei Oasis in the Shiyanghe River Basin as case study area,dynamically simulated the ecological effects under two typical urbanization modes through the method of scenario analysis. The results showed that,under the rapid-intensive urbanization mode,agricultural water consumption of the Wuwei Oasis could be limited in 6×108 m3 and 3×108-4×108 m3 agricultural water would be saved campared to the current level,production and living water consumption would also be reduced correspongdingly,and the total water consumption would not be more than 8×108 m3 in 2025. As a result,the gap between the supply and demand of water resources would be narrowed,and the ecological degradation of the Minqin Oasis in the lower reaches of the Shiyanghe River Basin would be effectively controlled. Otherwise,under the conventional urbanization mode,it would be difficult to effectively solve the water problems and to alleviate the ecological degradation of the Shiyanghe River Basin. Therefore,the rapid-intensive urbanization would be one of desirable modes for maintaining the stability of the ecosystem in the Wuwei Oasis and the Shiyanghe River Basin.
