摘　　要：山体是重要的地貌单元,保护以及合理利用山体资源可以让山体在城市发展中发挥出独特的生态价值和人文价值。本文利用GIS和RS技术,依据山水相依、自然衔接等原则来构建山体范围划定模型。同时,本文将逻辑回归模型运用到评价要素权重赋值,使要素权重分配过程更加科学,结果与区域特性更加匹配。以此为基础,将评价要素进行加权叠加分析,从而划定山体范围。从山体空间分布来看,山体主要分布于渑池县北部和中部。通过山体范围划定,为综合分析评价山体资源分布,以及科学合理编制山体保护专项规划提供基础支撑。Mountains are important geomorphic units.Therefore,the protection and rational use of mountain resources can make mountains play a unique ecological and humanistic value in urban development.In this paper,GIS and RS technology are used to build a mountain range delimitation model based on the principles of dependence of mountains and rivers and natural connection.At the same time,this paper applies the logistic regression model to the weight assignment of assessment elements,which makes the process of element weight assignment more scientific,and the results better match the regional characteristics.On this basis,the assessment elements are analyzed by weighted superposition,so as to delimit the scope of the mountain.In terms of the spatial distribution of the mountains,the mountains are mainly distributed in the north and middle of Mianchi County.The delimitation of the mountain range provides basic support for the comprehensive analysis and evaluation of the distribution of mountain resources and the scientific and reasonable preparation of the special plan for mountain protection.
