Abstract

Abstract: In order to determine the soil fertility of Moso bamboo forests at different altitudes in Dagang Mountain， soil physical and chemical properties， microbial properties and enzymatic activities were chosen as assessment indicators. Soil fertility was analyzed quantitatively by grey relational analysis， and ranked by correlation degrees comprehensively. The results showed that the order of soil fertility in Moso bamboo forests at different altitudes was 700 m>600 m>500 m>400 m>300 m. Correlation degree had a positive correlation with soil chemical properties， the number of bacterium， actinomycetes， activities of amylase， β\|glucosidase and polyphenol oxidase. Consequently， we concluded that soil chemical properties and soil enzymatic activities can be used as indicators for assessing soil fertility rapidly.

Key words: Phyllostachys pubescens, soil fertility, grey relation analysis, Dagang Mountain
