基于3S技术的吉林省靖宇县林下人参自然生境分析

摘要

为研究林下人参的自然生境，本文基于3S技术，利用ERDAS、ArcGIS等软件对Landsat8遥感影像进行解译分析处理，并提取坡度、坡向、海拔等地形因子参数，进行林下人参适宜生长环境因子分析。结果表明，林下人参适宜生长的坡度范围是6~24°，坡向为N坡、NE坡，海拔高度为506~767m。3S技术的应用，为林下人参自然生境分析提供了定量的研究方法，林下人参的自然生境研究对吉林省人参主产地区靖宇县的经济发展具有重要指导意义。%Based on 3S technology platform, this paper makes an analysis of the environment factors on the growth of under- forests Ginseng by interpreting and analyzing the Landsat8 remote sensing image and extracting the topography factors of slope, aspect and altitude with ERDAS and ArcGIS respectively. The results show that a gradient range of 6~24° , slope aspect of north and northeast, and altitude range of 506~767 meters are suitable factors. The application of 3S technology provides a quantitative method. The research has a guiding significance to the economic development of Jingyu County.
