Niche dynamics of main populations of plants communities in the restoring succession process in Horqin Sandy Land
科尔沁沙地植物群落恢复演替系列种群生态位动态特征

In this paper the niche dynamics of main species were studied with 6 types of grassland community sampled in the process of vegetation restoration in Horqin sandy land. Our results showed that there are obvious succession stages in the restoration process and that each stage is marked by a typical community, which is dominated absolutely by one species with the largest niche breadth in the community. The changes of niche breadths in the succession series properly reflect the population dynamics and can be a...
