摘　　要：以ENVI为平台,采用监督分类方法,解译西双版纳1996年和2016年两个时期的遥感影像。对监督分类后的结果进行分析,主要结论如下:①林地和橡胶为主要类型;②林地减少,橡胶用地扩大并聚集成片,且橡胶是面积增长最多、变化强度最大的地类;③橡胶主要由林地和耕地转化而来,说明这段时期内受到较大程度的人为干扰;④景观格局的优势度变大,景观异质性和稳定性降低。The spatial and temporal change patterns in land use were quantified by interpreting Landsat images from 1996 and 2016 and using the method of landscape ecology, and various landscape metrics were calculated at class and landscape levels. The main conclusions are as follows :①The pattern of land use was mainly composed of forest land and rubber in the study area;②However there was a decrease in forest land, on the contrary, rubber area was expanded and gathered. In addition, the rubber’s the change intensity and the area of the growth were the most large among all the class.③Rubber was mainly transformed form forest land and farmland. Therefore, this study area suffer from a larger degree of human disturbance during the study period.④ During the period between 1996 and 2016, the dominance increased, the landscape heterogeneity and landscape stability reduced.
