- Abstract:
-
In the process of vegetation secondary succession after abandoned farmland, soil organic carbon and microbial carbon both showed the trend of first drop then rising.The soil organic carbon and microbial carbon content was 115% and 82.9% of nature forest after 75-year abandoned, both of them had a positive relationship (P<0.05), moreover, microbial metabolism entropy and microbial carbon showed significant negative correlation (P<0.01) which showed an increase after the first downward trend. In the early stage of secondary succession, the content of the effective matrix was decreased, then increased in the late succession, which helped to increase the content of soil organic carbon, microbial carbon and soil fertility.
