- Abstract:
-
Soil active organic carbon is directly involved in soil biochemical conversion, which affects soil enzyme activities and plays an important role in soil available nutrient contents. The relationship between soil active organic carbon, its components and soil enzyme under three types of forests in Lushan were analyzed. Results are as follows. Firstly, the average WSOC and DOC contents decreased in the order: broadleaved forest > mixed wood > coniferous forest, while the ROC contents from high to low level is mixed wood > broadleaved forest > coniferous forest. The average MBC under mixed wood was much more than those under the other two forests and coniferous forest was the lowest. Secondly, soil intertase activity under three types of forest decreased in the order: mixed wood > broadleaved forest > coniferous forest. Urease activity and polyphenol oxidase activity varied in the same order as that of soil invertase activity. cellulase and acid phosphatase activity from high to low level is coniferous forest > mixed wood > broadleaved forest, while catalase activity decreased with an opposite order. Thirdly, components of soil active organic carbon under three types of forests were closely related to soil invertase and cellulose activity but no obvious positive correlation was noted between components of soil active organic and polyphenol oxidase and catalase activity.
