水资源可再生能力综合评价的遗传加权物元模型

为了科学地计算水资源可再生能力评价指标的权重 ,使评价方法具有可操作性 ,采用主、客观相结合的赋权基点法 ,以全局收敛的格雷码加速遗传算法为工具来确定权重 ,并结合物元分析理论 ,建立了一种新的评价模型——遗传加权物元模型 .文中给出了该模型实施的详细步骤 ,对黄河流域 9个行政分区的水资源可再生能力进行了综合评价 ,取得了较好的效果 .

A Genetic Matter Element Model With Weights For Comprehensive Assessment of Water Resource Reproducible Ability

In order to assess the index weights of the water resource reproducible ability scientifically and easily, using global convergent gray code genetic algorithm as a tool, and combining matter element analytic theory, this paper establishes the optimization model that determine the weight by use of the basic point by synthesizing subjective and objective information, and a new assessment model is established for comprehensive assessment of water resource reproducible ability—genetic matter element model with weights. And a detailed step is developed for this model. This model is used to assess the water resource reproducible ability of the 9 administrative divisions of the Yellow River. The result shows that the water resource reproducible ability of the Yellow River is rather low. Good result and effect are obtained.
