区域水资源优化配置模型中子区权重分析

Sub-region weight analysis in optimal allocation model of regional water resources

子区权重系数的确定是区域水资源优化配置中一项复杂而又重要的工作.对于区域面积较大、区划较多、影响因素复杂的水资源优化配置问题,子区权重分析是无法避免的.针对这种情况的子区权重系数的计算方法加以探讨,并结合大型灌区的实例予以分析.结果表明,对于区域面积较大、区划较多、影响因素复杂的优化配置,采用层次分析AHP法方法计算子区权重系数是可行的.

Determining the sub-region weight coefficient is a complex and important task in optimal allocation of regional water resources. It is inevitable to analyze sub-region weight when optimal allocation problems of water resources, with larger regional areas and more sub-regions and complex factors, are to be solved. Under this circumstance, this paper studies calculation method of sub-region weight coefficient, and applies it in large irrigating district. The results show that it is feasible to adopt AHP（analytical hierarchy process） to calculate the sub-region weight coefficient in optimal allocation of larger regional areas with more sub-regions and complex factors.
