Study on ecological water requirement of Ejina Oasis
摘要
Abstract
Based on the measured runoff data and the RS interpretation, the relationship between ecological conditions of Ejina Oasis and water resources was analyzed. The results show that in terms of time scales or from the spatial scale, the evolution of the ecological environment in Ejina Oasis and water resources are among the obvious positive correlation, and reduction of water resources is a decisive factor for the ecological degradation. On this basis, according to the characteristics of water production and water consumption of Northwest inland rivers, this paper proposes that ecological water use of the oasis, which yields weak runoff, is required by a certain amount of water recharge to maintain the oasis, and a "tangent" model for ecological water requirement calculation of Ejina Oasis has been established. By comparison with other methods the reasonableness of this model is verified, and the method provides support for the calculation of ecological water demand in the oasis areas of Northern region and the development of water resources management program.关键词
