Abstract:Micro-site heterogeneity was one of the important mechanisms of maintaining species diversity in plant community. Topography as a source of heterogeneity did not receive enough attention. In this paper, a terrain surface of 0.96 hm~2. was simulated using Data Elevation Model (DEM) to analysis how landform influences community structure in small scale.The research site was located in Shengnongjia area of Hubei Province (31°19′4″N, 110°29′44″E). This area is at transitional zone from middle to northern subtro...
