| Abstract: |
| Water resources are scarce and the conflict between water demand and supply is outstanding in the inland river basin of arid areas, and water competition is drastic among upstream, middle and down streams. The allocation of water resources usufruct has remarkable theoretical and practical value in solving the conflict of water resources among regions and rational utilization of water resources in a river basin. The optimized allocation principles are set out, according to available water and net water requirement in different planning years, and water requirement per capita food are treated as constraint on lower bound, the multiobjective optimal allocation model of water resources usufruct is established which include efficient and equitable objective. Taking Shiyang River Basin as an example, the allocation in view of transferred and self-production water in different planning years are obtained, and the results show that the differences of water shortage rate among districts decrease obviously. Production water resources usufruct in Jinchuan increase markedly when compared with “The major treatment planning of Shiyang River Basin” water allocation scheme, achieve efficiency and equity of water resources usufruct. |
