【摘要】 采用遥感和GIS一体化技术,利用1976年的M SS和2004年的TM两个时期的遥感影像数据对云南边境地区的土地覆盖动态变化进行监测,并对变化的时空特征进行分析。结果表明土地覆盖现状以森林和裸岩地为主,其次是耕地和水域。土地利用/覆盖变化主要发生在林地、水域、耕地和裸地四大地类中,林地减少了6.95%,水域减少了2.08%;耕地增加了4.04%,裸地增加了3.67%。并对土地变化所引起资源和环境问题及其驱动因素进行了初步的探讨和分析。更多还原

【Abstract】 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.更多还原
