摘　　要：近些年,中国城市与乡村一体化进程不断加快,各种土地建设活动对资源的需求日益增加,引发了一系列的生态环境污染问题。研究人员对此提出"生态屏障"的概念并进行了深入探讨,认为生态屏障的提出丰富并开拓了生态的发展方向,为生态环境建设提供指南。本文从林地与地形角度分析出发,通过收集整理遥感影像、DEM等基础数据,以VM-MapInfo软件为基本技术支撑,综合地形分析、植被指数分析、叠加分析等技术方法,得到最终的识别数据,初步划定生态屏障区域,对于保障市县域生态安全具有重要作用。In recent years,China’s urban and rural integration process has been accelerating,and various land construction activities have increasingly demanded resources,which has caused a series of ecological and environmental pollution problems.Researchers put forward the concept of"ecological barrier"and conducted in-depth discussions,believing that the proposal of ecological barrier enriches and opens up the direction of ecological development,and provides guidance for the construction of ecological environment.Starting from the analysis of forest land and terrain,this paper collects and arranges basic data such as remote sensing images,DEM,and uses VM-MapInfo software as the basic technical support.Comprehensive terrain analysis,vegetation index analysis,overlay analysis and other technical methods are used to obtain the final identification data.Preliminary delineation of ecological barrier areas plays an important role in ensuring the ecological safety of cities and counties.
