Abstract

The study was conduced by sampling and analyzing 23 soils under Phyllostachys praecox f .prevelnalis forests which located across 4 villages and towns in Lin'an City in spring 1999 .The results show that the variation coefficients of enzyme activities are 33.37 %, 71.00 %, 49.60 %, 39.90 % and 28.08 % of hydrogen peroxidase , sucrase , phosphatase , urease and protease respectively .Protease activity has a good relation to soil organic matter , hydrolytic nitrogen , avaiable phosphorous , rapid potassium , sucrase and urease , and the correlation coefficients are 0.801 , 0.962 , 0.783 , 0.049 , 0.441 and 0.845 respectively .Protease activity could be a good index of soil fertility .Correlation coefficient between phosphatase and soil avaiable phosphorous is - 0.875 , indicating an excess of soil phosphorous .All enzyme activities except phosphatase has a negative relation to blossoming percentage of bamboo and sooty mould susceptibility index , among them peroxidase and sucrase are significant negative-related to blossoming percentage .Therefore , enzyme activities , especially peroxidase and sucrase activities , could be regard as an index of bamboo forest deterioration .
