摘要
土地利用是人类活动最直观的反应，人地关系是影响环境变化的主体因素，是制定区域可持续发展、实施生物多样性保护的内核；航空航天遥感（ＲＳ）从时间和空间上扩大了人们的视野，是监测自然因素和人为作用所引起森林植被及土地利用动态变化的有力、高效的手段。在ＲＳ技术支持下，采用不同年代、不同分辨率、不同比例尺，时间跨度为３０年的航空航天遥感，对热带雨林景洪巴卡土地结构及变迁进行分析研究，探索森林土地空间动态变化对土地利用、可持续发展的影响，对区域环境的影响等，为当地政府提供决策依据。
Land use is the most visual response of human activities,man-land relationship is the main factor affecting enviromental changes,and the core enacting regional sustainable development and implementing biodiversity protection.Remote sensing,which broadens people′s visual field of space time,is the strong efficent means of monitoring natural factors and dynamic changes of forest vegetation and landuse caused by personal action In this article,land structure and changes of Baka,Jinghong are analysed and studied,it is probed that spacial dynamic changes of forest land cause effects on land use,sustainable development,regional environment by taking use of the different years,the different resolution ratio,the different scale RS data being full of 30 years time span,at last providing decision basis for local government
