| 摘 要： | 土地利用/覆盖变化研究是全球变化研究的热点之一。应用遥感、GIS技术及数理统计学的方法，利用1976年MSS和2004年TM二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研究，并对变化的时空特征进行了分析。结果表明，土地覆盖现状以森林和裸岩地为主，土地利用/覆盖变化的主要方向是林地向裸地和耕地转化。

| Abstract: | The research on the land use/cover change is one of the frontiers and hot spots in the global change researches.Based on remote sensing and GIS technology,the authors analyzed the spatial-temporal characteristics of land use/cover change in the border areas of Yunnan province by using MSS and TM data acquired in 1976 and 2004 respectively.The analytical result of remote sensing shows that the surface features are mainly forests and naked rocks,and subordinately farmland and waters.Remarkable changes include four types,namely,forestland,waters,farmland and naked land.Forestland and waters have decreased by 9.72% and 1.84% respectively,while farmland and naked land increased by 5.74% and 4.44% in the past thirty years.The problems of ecological environment and resources and the driving factors resulting from land use /cover change in the border areas of Yunnan province are analyzed |
