摘要：The "space instead of time" method was used to determine the species diversity and soil property in different succession stages in Karst rocky desertification area, in China. The species diversity of herb layer was digressive and that of tree layer, shrub layer and the whole community were increased first and then decreased, the peak value appeared in the rattan thorn scrub stage, the lowest appeared in the grass stages. At the beginning of succession, the species diversity of herb layer was higher than that of shrub layer. With the closing time increased, the diversity of the shrub layer increased more than that of herb layer. There had the same change trend in velocity nitrogen, organic matter, total nitrogen and total phosphorus. There was significantly linear positive correlation between the total nitrogen, phosphorus, magnesium, calcium, pH, available phosphorus and the species diversity and richness of the herb layer.
