| Abstract: | Using the method of main ingrediant andlysis in researchs of refrogradation of karst soil enviroment that can reveal the representative sensitive ones (main ingradations) from numerous soil factors, and meanwhile provide a new reference for systematic classification of karst soil enviroment. It shows that the method of main ingrediant analysis provides an effective statistics for discussing the refrogradation of karst enviroment. |
