投影寻踪技术在瓦房店市水资源安全评价中的应用

Application of projection pursuit technique in water security assessment of Wafangdian City

利用统计软件DPS中的投影寻踪综合评价法选取最优投影方向,以最优投影方向所对应的投影特征量作为评价依据,得出瓦房店市水资源分区各区的水资源安全状况:松树库上地区为安全性最高区域,回头河为安全性最低区域。研究表明,该方法对水资源安全评价有较好的评价能力。

The projection pursuit comprehensive evaluation method of DPS was used to select the optimal projection direction and the projection metric corresponding to the optimal projection direction was considered the basis for evaluation. The water resources security situation in Wafangdian City can be described as follows： the area above Songshuku was the highest security zone,and the Huitou River was the lowest security zone.This study showed that the method had a better evaluation capacity for security assessment of water resources.
