NUMERICAL ORDINATION OF DIMENSIONAL SPATIAL PATTERNS FOR NATURAL SECONDARY FOREST
天然次生林多维空间格局的数量排序

The investigation of 39 field plots for natural secondary forest in southern and western mountainous areas of Henan Province shows that the composition and distribution patterns of secondary forestry community with gradual change in dimensional ecological space.The models of principal Component Analysis (PCA) and Regression Analysis (RA) were developed with both 27 arborous edification and 6 major environmental factors.They will provide theoretical basis for forestry production,forest type distribution and tree species arrangement in Henan Province.
