摘要: 本文以西双版纳为研究区域,通过解译2009、2014、2018年3期遥感影像,提取土地利用数据,利用转移矩阵和分形理论,定量分析不同时期土地利用空间结构的复杂性、稳定性及变化规律。研究结果表明:该地区近十年居民点和橡胶园面积有所增加,林地面积相应减少;其中居民点主要由橡胶园和耕地转化而来,橡胶园主要由旱地和林地转化而来;林地主要转化为灌木和橡胶园;根据分形理论中分维数及稳定性指数得出,居民点的空间结构最为规则,空间分布最为稳定,林地、橡胶园的空间结构较为简单,旱地内部镶嵌结构复杂,边缘粗糙,分布规律趋向于随机。

Abstract: In this study, remote sensing images of Xishuangbanna region in 2009, 2014 and 2018 are interpreted to obtain land use data. The transfer matrix and fractal theory are used to quantitatively analyze the complexity, stability and change rules of spatial structural of land use in different periods. The results indicate that the areas of residential land and rubber plantation have increased in the past ten years, while the area of forestland has decreased. The residential land is mainly transformed from rubber plantation and cultivated land, and rubber plantation is mainly transformed from dryland and forestland. In addition, forestland is mainly transformed into shrub and rubber plantation. According to the fractal dimension and stability index of fractal theory, the spatial structure of residential area is the most regular and the spatial distribution is the most stable. However, the spatial structures of forestland and rubber garden are relatively simple. The internal mosaic structure of dryland is complex, with rough edge and random distribution law.

Key words: land use, fractal, spatiotemporal characteristics, remote sensing, Xishuangbanna
