The necessity and feasibility of an ET-based modern water resources management was analyzed to improve assessment of critical water resources scarcity in the region/basin. This analysis was based on the whole water cycle process and its analysis object is evapotranspiration (ET), a main consumption component in the water resources dynamic transformation process. A case study was undertaken by selecting soil water resources in the Yellow River Basin and employing the WEP-L distributed hydrological model with... 相似文献

Formation and utilization of water resources of Tarim River 总被引:3,自引:0,他引:3
The Tarim River is a typical inland river in arid area without runoff yield of itself, and water resources are all supplied by its headstreams. The method of time series analysis is applied to annual runoff series of three headstreams, namely the Aksu River, Yarkant River and Hotan River to analyze their dynamic variations. A model is established to estimate water consumption in the headstream areas. Quantitative results indicate that both total annual runoff of headstreams and water consumption in the headstream areas have an increasing trend. The dynamic trends of annual runoff of hydrologic stations along the mainstream of the Tarim River are also presented to estimate the intermittence drying-up time at each station. Water consumption model of the mainstream area is used to analyze the characteristics of water consumption in the upper and middle reaches. It is shown that water consumption in each river reach of the mainstream decreases with the decrement of inflow and increases with human activities. 相似文献
