Sample plots (15 m × 20 m) were set up in the karst areas in Guizhou Province with an attempt to reveal the changes of soil enzyme activities under karst forest degradation. The results showed that the extent of degradation of plant communities was enhanced leading to the clayification of soil, the drastic decrease in SOM contents, and the reduction of soil nutrients available for plants. The urease activities, peroxidase activities and alkaline phosphatase activities of the soils had also decreased significantly.
