摘    要:针对区域水资源承载力状况,采用高维降维技术--投影寻踪分类模型(PPC),利用基于实数编码的加速遗传算法(RAGA)优化其投影方向,将多维数据指标(样本评价指标)转换到低维子空间,根据投影函数值的大小评价出样本的优劣,从而最大限度避免了灰色关联法评判中权重矩阵取值的人为干扰,取得了满意的效果,为区域水资源承栽力状况评价及其他评判问题提供一条新的方法与思路.

关 键 词:实码加速遗传算法  投影寻踪模型  水资源承栽力  综合评价

Abstract:According to regional water resources carrying capacity,through applying PPC model and using RAGA based on real-coding to optimize projection direction,the multi-dimension data is turned into low dimension space.So the sample can be evaluated good or bad according to the projection value.Thus,the jamming of weight matrix value in the gray correlation evaluation method can be avoided,and better result is obtained.It provides a new approach for the comprehensive evaluation of water resource carrying capacity ...
Keywords:RAGA  PPC  water resource carrying capacity  comprehensive evaluation
