Abstract

Abstract

Five kinds of land uses are taken to elucidate the soil quality changes in Huajiang karst canyon, Guizhou province. The results show that the soil quality changes evidently under different land uses. The soil quality under different land uses was studied by means of the soil quality index(QI) and the soil deteroration index(DI) in the paper. Results from both methods show a similar trend of soil quality under different land use condition, that is Shrubs land＞ High-forest＞Reforest land＞Arable land ＞Grassland. In addition, correlative analysis of the two methods reveal that, there is a significant linear correlation between DI and QI, with a R2 value of 9.277. Both methods are efficient in the evaluation of the soil quality levels under diffetent land uses.
