Investigation Of Initial Water Rights Allocation On Yellow River Irrigation Areas Of Ningxia

Ningxia, where there are rare water resources, is drought district in Northwest Plateau. In Ningxia, stable and high yield of agriculture mainly depends on water diversion of Yellow River Irrigation Areas. With local economic development, the water resources demands of life, industry, agriculture and zoology gradually increase, and local water as well as foreign water can't meet future requirement of development. At present, the studies on initial allocation of water rights at home are in its primary step, whereas the allocation of water rights is usually restricted to macroscopically theoretical instruction and lack microscopically quantitative studies. According to the practicality of Yellow River Irrigation Areas in Ningxia, a novel pattern of water rights allocation is presented and the specific values of local water rights allocation are obtained in this paper. Then, the study focuses on Yellow River water consumption demand. According to the phenomenon that there are large water diversion and drainage in Irrigation Areas, a practical solution, which takes on important meaning in local economic development and the construction of economical society, is developed.This paper studies Yellow River Irrigation Areas of Ningxia. Main contents and contributions are summarized as follows:1 In terms of the principles of efficiency, equity and sustainability and according to the practical situation of Ningxia Irrigation Areas, 15 indexes, which establish the index system of initial water rights allocation, are screened out and hierarchical structure model is developed. With DELPHI method, the indexes weights are marked by experts. The results are used to make consistency check of decision matrix. Finally the initial water rights values of 5 cities in Ningxia are obtained. Finally the initial water rights values of the 5 Ningxia cities -Yinchuan City, Shi Zuishan City, Wuzhong City, Zhongwei City and Guyuan City.2 With 14 counties in Ningxia Irrigation Areas as basic unit, indexes of social and economic status, as well as rations of water requirement and consumption, from 2000 to 2002 are summarized. Then every county's water demand rights and water consumption rights of life, production and zoology are calculated respectively. The results shows that in Irrigation Areas 14 counties, the gross water demand rights of present year is 6531million m~3, gross water consumption rights of present year is 3246 million m~3,forecasted gross water demand rights of 2010 is 6672 million m~3,gross water consumption rights of 2010 is 3429million m~3.
