改进投影寻踪模型在黄河甘肃段流域水运污染评价中的应用
Application of improved projection pursuit model in water transport pollution assessment of the Gansu Section of the Yellow River Basin
摘要
Abstract
[Objective]To identify the water transport pollution problems in the Yellow River Basin,the water environment status of the basin was scientifically evaluated,[Methods]taking the Gansu section of the Yellow River Basin as the research back-ground,considering the nonlinear relationship between water transport pollution and various risk factors,a projection pursuit IPP model that can fully mine indicator information and handle complex nonlinear problems with multiple factors was used to evaluate water transport pollution.In order to ensure optimal weights,the adaptive particle swarm optimization algorithm APSO was incor-porated to optimize weights for clustering and partitioning of water transportation pollution levels.The sensitivity analysis of each indicator was conducted using the single factor rotation OAT method.[Results]The result indicated that the classification level of each region showed an upward trend from west to east,rising from level Ⅱ(generally severe)to level Ⅲ(severe).The evalua-tion result were consistent with the actual situation,verifying the reliability of the method.In the future,emphasis should be placed on strengthening the management of the eastern region.[Conclusion]This evaluation index system can effectively identify the main problems of water transport pollution in the Yellow River Basin from multiple perspectives,and help improve the risk assessment index system of water transport pollution in the Yellow River Basin.The research result provide certain reference value for the current planning of water transportation construction in the Yellow River Basin.关键词
