基于遥感和GIS技术，利用1976年和2004年的MSS和TM数据，分析了云南省跨界土地利用/覆盖变化的时空特征。遥感分析结果表明，云南省跨界土地利用/覆盖变化以森林和裸岩为主，其次是农田和沃茨。结果表明，云南省跨界地区土地利用/沃茨被变化引起了一系列生态环境和资源问题，并分析了跨界地区土地利用/覆被变化的驱动因素。
Based on remote sensing and GIS technology,the author analyzed the spatial-temporal characteristics of land use/cover change in the trans-boundary of Yunnan Province by using MSS and TM data which were acquired in 1976 and 2004 respectively.The analysis result of remote sensing showed that most of the surface features are forest and naked rock,and the second is farmland and waters.Remarkable change happed in 4 types,namely forestland,waters,farmland and naked land.Forestland and waters deceased by 6.95% and 2.08% respectively,while farmland and naked land increased by4.04% and 3.67% about thirties year.Land use /cover change resulted in a serial of problems of ecological environment and resource,the driven factors in the transboundary area of Yunnan Province in China were analyzed.
