Abstract Xishuangbanna is one of the largest tropical forest vegetation and highest biodiversity regions and also an important rubber-producing area in China. This paper has studied the impacts of rubber plantation on the fragmentation of tropical forests and its substitution for natural forests. It is concluded that the rubber plantation in Xishuangbanna shows significant geophysical patterns and high spatial and temporal dynamics. Rubber plantation has had no significant impacts on soil erosion but has evidently accelerated fragmentation, resulting in the homogeneity of landscape. Although rubber plantation has social and economic benefit in a certain degree, it has obviously threatened the biodiversity and stability of the tropical forest ecosystem.
