2014-2021年朝阳市土地利用的动态遥感监测

Dynamic Remote Sensing Monitoring of Land Use in Chaoyang City from 2014 to 2021

土地利用动态遥感监测可以揭示土地利用变化规律,为宏观管理提供依据。本文以朝阳市双塔区和龙城区为研究区,选用2014-2021年的5期Landsat卫星遥感影像数据,利用ENVI软件分析双塔区和龙城区土地利用现状和发展趋势。其间采用监督分类法将朝阳市土地利用类型分为林地、草地、耕地、建设用地和水域五大类,通过对比各期土地利用和植被覆盖变化,综合评价朝阳市土地利用转化情况。

Dynamic remote sensing monitoring of land use can reveal the law of land use change and provide a basis for macro management. In this paper, Shuangta District and Longcheng District of Chaoyang City are taken as the study area, and five phases of Landsat satellite remote sensing image data from 2014 to 2021 are selected to analyze the current situation and development trend of land use in Shuangta District and Longcheng District by using ENVI software. During this period, the supervised classification method is used to divide the land use types of Chaoyang City into five categories,namely forest land, grassland, cultivated land, construction land and water area, and the land use transformation in Chaoyang City is comprehensively evaluated by comparing the changes of land use and vegetation cover in each period.
