科尔沁沙地两种主要植物群落的演变特征

Succession Features of Two Main Communities on Horqin Sandy land

本文通过对科尔沁沙地两种主要植物群落沙漠化连续演变过程的研究,对上述问题进行了初步探讨。

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.
