摘    要:以中国某区域为例,建立了区域水资源可持续利用预警指标体系及其等级标准,用基于加速遗传算法的模糊层次分析法确定各预警指标的主观权重,用基于加速遗传算法的投影寻踪方法确定各指标的客观权重,然后用最小相对信息熵原理计算各指标的组合权重,进而提出了基于熵组合权重的区域水资源可持续利用预警新模型(CWF)。结果表明,用CWF进行区域水资源可持续利用预警,可充分挖掘预警过程中主观经验信息和客观资料信息,物理概念明确,计算结果合理,方法通用,具有一定的推广应用价值。

关 键 词:水资源可持续利用  预警模型  组合权重  信息熵原理  模糊层次分析法  投影寻踪

Abstract:As a new development form of evaluating regional water resources sustainable utilization,forewarning regional water resources sustainable utilization is an important adjust and control measure for regional security management,nowadays the research belongs to qualitative analysis and lacks quantitative forewarning model with operability.For this reason,an index system of forewarning regional water resources sustainable utilization and its grading criterion was established according to some research region of China,subjective weights of forewarningindexes can compute by using accelerating genetic algorithm based fuzzy analytic hierarchy process,objective weights of forewarningindexes can be computed by using accelerating genetic algorithm based on projection pursuit method,the two kinds of the weights can combine comprehensive weights of forewarningindexes by using minimum relative information entropy principle,and the comprehensiveforewarningindex of regional water resources sustainable utilizationcan be obtained according to the comprehensive weights and standardization values of forewarningindexes,which formed a new model for forewarning regional water resources sustainable utilization,named CWF for short.The research result shows that as anew forewarningmodel of regional water resources sustainable utilizationwith distinct concept of mathematics and physics,both subjective and objective information is sufficient by using CWF,its computation result is reasonable,its method is general,so CWF can be applied to different forewarning regional water resources sustainable utilization.
Keywords:water resources sustainable utilization  forewarning model  combined weight  principles of information entropy  fuzzy analytic hierarchy process  projection pursuit
