摘要
以Land Sat多时相影像为数据源,采用基于规则的面向对象分类方法,监测会理县2000~2015年地表覆盖变化。结合1∶50 000 DEM数据,分析了会理县地表覆盖构成与转移、变化动态度及潜在退耕地情况。监测分析结论能为会理县加强空间管制、促进土地资源集约利用、指导生态文明建设等提供决策信息支撑。
In this paper, the land cover change has been monitored using object oriented classification method based on Landsat muhitemporal images, in Huili County, from 2000 to 2015. The structure and transfer, change dynamic degree, and potential lands to grain for green project had been analyzed based on the land cover change data and digital elevation model of 1 ： 50 000. The conclusions of monitoring and analysis can provide some support to strengthen space control, promoting intensive land use, guide the construction of ecological civilization for Huili county.
