Effects of Intimate Natural Management of Aleurites montana Eco-Forests on Activity of Soil Enzymes

To investigate the intimate natural management effect on soil enzyme activities of Aleurites montana forests, separately selected 3 plots from Aleurites montana ecoforests of intimate natural management and normal management, and analyzed the activity of urease, invertase, acid phosphatase, catalase and polyphenol oxidase in each plot. The results showed that 5 enzyme activities of intimate natural management plots were higher than those of normal management plotsespecially, the activities of urease and polyphenol oxidase were significantly enhanced. So the soil quality could be improved by intimate nature management of Aleuriyes montana, thus solving the soil problems in artificial management forest. Therefore, it is worth popularizing in the nature approximating forestry.
