【摘要】 针对水资源系统可持续利用评价问题,采用投影寻踪聚类模型,将多维数据指标转换到低维子空间,并优化其投影方向,根据投影函数值的大小对水资源系统可持续利用的程度进行合理评价。应用表明,该方法能利用一个综合反映多因素之间复杂关系的特征指标给出相应的评价结果,根据计算结果可以分析影响水资源系统可持续利用的主要因素,为水资源系统可持续利用的评价提供一种计算过程简单、直观的新方法。更多还原

【Abstract】 This paper is to classify the water resources system sustainable utilization according to projection function value through transferring multi dimension data indexes into low dimension space by using projection pursuit cluster (PPC) model. The result shows that the method can construct a characteristic index, and the main impact effects can be analyzed according to the result. The model is qualified with simplicity and can provide a new approach for water resources system sustainable development更多还原
