In order to change the low-quality forest stands into qualified forest stands with desirable productivity and other ecological benefits, it is necessary to adjust the stand structure and functions. In this study, a low-quality forest stand after strip clearcutting in the Lesser Khingan Range of China was investigated, and the principal component analysis and membership functions were combined to evaluate the integrated soil fertility in different experimental strips (horizontal strips: S1-6 m×100 m, S2-8 m×100 m, S3-10 m×100 m, S4- 15m×100 m; Vertical strips: H1-6 m×100 m, H2-8 m×100 m, H3-10m×100 m, H4-15 m×100 m). Results showed that most soil fertility indexes of the experimental strips showed moderate varia... view more»
