Features of Water for Ecological Demand in Arid Area in the Northwest China

Abstract:

Along with the implementing of eco-environment protection and socioeconomic development, water resource is a serious problem in Northwest China.Moreover,the socioeconomic development has been constrained.Meanwhile,a kind of ecosystems security has been threatened in the arid area.Based on the strategy of water source sustainable development, the principle and method of water for ecological demand (WED) are urgent in need of resolution. The actual features can be understand by case study in the artificial forest ecosystem and desert riparian ecosystem.With the guidance of eco-hydrology, WED features is obviously in arid area. The quality and quantity of WED have a larger variable range. Meanwhile, water use style is flexible. WED is under the control of water cycling and transfer efficiency of SPAC, which has close relation with vegetation growth.WED Estimation focused on some parameters and modeling. The ideas in WED have significances for improving eco-hydrology and water resource management and ecological practice as well as sustainable development of ecological industry in arid area.
