摘要: 本文通过对云南省玉溪市红塔区2000年1月的TM遥感影像图和2015年1月的OLI遥感影像图进行监督分类及对比研究,结果发现:相比于2000年,2015年分类后处理得出耕地、林地、水体、建设用地、其他用地等主要地物的时空变化,林地、耕地面积大幅度减少,建设用地增加迅速。此研究对我国云南省玉溪市红塔区的土地利用进行了分析,旨在关注其变化,以便对玉溪市的土地管理和规划提出合理的科学依据。
Abstract: Based on remote sensing images of two time periods of TM image 2000-2015, the RS and GIS software were used to classify the remote sensing images and to obtain the cultivated land. The spatial and temporal changes of main objects such as woodland, water, urban land and other land, the land cultivated land area decreased substantially, the construction land increased rapidly. This study was analyzed aiming to pay attention to the change of Hongta District in Yuxi City, Yunnan province in order to provide reasonable scientific basis for land management and planning in Yuxi City.
