| 中文摘要: |
| 干旱区内陆河流域水资源短缺，供需矛盾突出，上中下游用水竞争强烈，水资源的使用权分配对解决流域内不同区域间用水冲突和水资源合理利用具有重要的理论与实践价值。提出干旱区内陆河流域水资源使用权的优化分配原则，考虑不同规划年可利用水资源量和净需水量
，以流域人均自产粮食需求需水为水资源使用权分配的约束下限，建立多目标优化分配模型。以石羊河流域为例，得到在不同规划水平年下分别考虑外调水和自产水情况下的流域水资源使用权的分配方案。结果表明，各行政分区缺水率差异明显减小，并与《石羊河流域重点
治理规划》分水方案比较，金川区生产用水使用权分配显著增加。 |

| 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. |
