Abstract: Succession features in the species, density, coverage, above-ground mass of two main communities are analysed. The results show that succession tendencies of two communities are similar, but succession speed of semi-bush community is faster than that of herbage community. The process is continuous or discontinuous mainly depending on the land desertification process.
