| According to the dynamic characteristics of water rights and the conditions of Shiyang River basin,the evolvement of water rights is divided into historical water rights,present water rights and future water rights.By analyzing the formation of historical water rights,this paper used AHP method,combined with the principles of index screening and built an initial water rights allocation model in Shiyang river basin.The model involved many aspects such as society,economy,resources,technology,management etc.We developed a semi-structure,multi-clayer and multi-object index system of Shiyang River basin water rights allocation.The results from the model are approximately consisting with the distribution amount of Water by the Gansu Water Conservancy Department in 2005; it is feasible to allocate initial water rights of Shiyang river basin.Therefore,we use the model again,with the predicted results of indexes in Shiyang River basin in 2010,through the method of expert estimation,we can get future water rights allocation proportion and the distribution amount,this can be used as a guidance for basin sustainable development. |
