Study on Water Rights Transfer Stage

摘要

In arid area lacking water resources restricts the development of economy and society. For pursuing maximum economic interest, eco-environmental water was used by economic water and agricultural water was occupied by industrial water. Based on this, the idea of water rights transfer is presented. The water rights transfer is divided into such four stages as Original Ecology Stage (OES), Agricultural Water Use Stage (AWUS), Industrial Water Use Stage (IWUS) and Ecological Rehabilitation Stage (ERS) by using the percentage of ecological water use, increasing rates of agricultural and industrial water use. The water rights transfer stage in 2000 for sub-basin China is divided. Based on water resources, social and economic characteristics for sub-basin, the boundary of AWES and IWES is determined. By using the boundary, the water rights transfer stage for some countries is discussed. The results show the stage division is reasonable by demonstration analyzing Yellow River Basin, Shiyang River Basin, Shule River Basin and Hei River Basin.
