Abstract:
In order to explore the relationships among soil nutrient,enzymatic activity and death of Abies fanjingshanensis，the samples were collected from death plots(Dp) and living plots(Lp).Soil pH，SOM，TN，AN，AK，TK,TP，AP，CEC content and the activities of urease，phosphatase，catalase，polyphenol oxidase were measured，and the relationship between soil nutrient and enzyme activity were analyzed.The results showed that all measured parameters were rich expect total phosphorus in both sample plots.The contents of AP，CEC and TK in Lp were higher than Dp，the rest of the nutrient contents did not differ much.The activities of urease and phosphatase in Lp were higher than Dp，the activity of catalase in Dp soil was higher than Lp，there was no obvious correlation between all enzyme.A significant correlation was observed between urease activity and SOM in Lp soil of Abies，AK and CEC content had a positive correlation with urease activity，catalase activity had a positive correlation with AN，Alkali hydrolysis nitrogen，total nitrogen had a notable positive correlation with the activity of polyphenol oxidase.Catalase activity had a negative correlation with CEC，there was a negative correlation among TP，TK content and polyphenol oxidase.Meanwhile，there was a large negative correlation between phosphatase activity and AP content，and the other enzymatic activities had a low correlation with the other nutrient contents.
