【摘要】 西双版纳是我国热带雨林、季雨林分布区,人为干扰下森林的演变和发展趋势对当地牛态环境、社会经济发展、民族地区稳定繁荣都起着重要影响,本项目采用遥感(RS)与地理信息系统(CIS)复合的研究方法和技术,以1:20万基础电子地理底图为平台,以两个时相TM影像为主要数据源,结合地面调查、社区调查,对30年来西双版纳森林空间结构类型、动态变化等进行分析,并对该区域森林变化原因及分布格局进行研究及讨论。更多还原

【Abstract】 Xishuangbanna is a special area in China because of its original tropic rain forest and monsoon forest.With the development of regional economay and society, forest change caused by human action largely affectlocal enviromental condition. This will obstract local social economy development . It also influence the localstability and prosperity. In this project, by integrating technology of CIS and multi - temporal remote sensingimages, using digital map scaled 1:200 000 , taking two temporal periods of satellite remote sensing data assource, combined with field survey and social - economic investigation, the authors try to analyze the forest’sspatial structure types, dynamic change of Xishuangbanna forest in the past 30 years, and try to find the re-sults and causes of the change of spatial distribution pattern of forest.更多还原
