| 摘 要： | 底层土壤有机碳库占土壤总碳库的50％以上，但其控制机理仍不清楚．本研究以福建建瓯万木林自然保护区的杉木人工林为研究对象，采用改进的酶动力学分析方法，研究杉木林表层（0～10cm）和底层（40—60cm）土壤微生物生长对策的差异．结果显示，相对于表层土壤，底层土壤的易利用碳含量更高，表层土壤微生物更趋向于K对策，而底层土...

| Abstract: | Although the subsoil organic carbon pool accounts for over 50% of the total soil organic car- bon pool, its control dynamics still remains unclear. In this study, growth strategies of soil microbes in the topsoil （0 - 10 cm） and subsoil （40 - 60 cm） of a Chinese fir plantation in Wanmulin Nature Reserve in Jian＇ou City, Fujian province, China, were determined by the modified Michaelis-Monod equation. The results showed that, as compared to the topsoil, the subsoil had higher carbon availabili- ty. And, the microbial community of topsoil prefers K strategy, being different from that of subsoil which prefers r strategy. |
