摘　　要：将投影寻踪技术与遗传算法相结合,建立了基于实数编码加速遗传算法的投影寻踪评价模型,通过优化各指标样本的最佳投影方向,得到各样本的投影值,从而实现了区域水环境承载力的量化评价。最后,应用该模型对黄河中上游某支流流域地区水环境承载力状况进行综合评价分析,检验了模型的可行性和合理性。In order to analyze and evaluate regional water environment carrying capacity, a RAG-PPE model was built in this paper to get various projection values by optimizing the projection direction of each data set, combining projection pursuit approach with real coding based accelerating genetic algorithm. Finally, RAG-PPE model was applied to evaluate and analyze the regional water environment carrying capacity in Guanzhong area of Weihe basin, test the feasibility and rationality of the model.
