| Abstract: | Analyses the commumity characteristics of forest types qualitatively of natural Betula platyphylla forest in Mohe Forest Region, northeastern Great Xingan Mountain. The natural Betula platyphylla forests are ordinated by means of principal axes analysis (PAA) and polar ordination (PO) methods. Results of classification by ordination were corrected by ISODATA-Fuzzy cluster analysis. The main site factors of sample plots were also used to ordinate and analyses. Satisfactory results were obtained that ordination results are conformed to the actual vegetation and community characteristics. |
