摘要:
耕地弃耕后植被次生演替过程中土壤微生物碳的大小和活性的研究结果表明，土壤有机碳和微生物碳呈现先下降后增大的趋势；在75 a的弃耕地中，有机碳和微生物碳的含量达到天然植被的115%和82.9%，而且有机碳与微生物碳呈现显著正相关（P<0.05）；微生物代谢熵与微生物碳呈现极显著负相关（P<0.01），呈现先上升后下降的趋势；在次生演替初期，土壤有效基质逐渐降低，而在演替后期有效基质不断增加，有益于土壤有机碳和微生物碳的提高，有利于土壤肥力的提高。
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.
