Almost all the vegetation types occurred in a small study area, so the present study was typical and representative. The results show that the corrosional ratios of different vegetation types at different elevations are quite different. In general, the corrosional ratios increase gradually from the forest land of Shuifang spring, through the bamboo forest land of Shuifang, the meadow of Shuifang and the forest of Bitan spring, to the shrub of Bitan spring.
