不同林龄橡胶林割胶前后土壤微生物碳代谢功能多样性进行研究。结果表明：随着培养时间延长，土壤微

13、18、25、30 年橡胶林割胶后（11 月）土壤微生物AWCD 值、Shannon-Wiener 指数、McIntosh 指数和利

| 英文摘要: |
| The functional diversity soil microbial carbon metabolism and its changes at different aged rubber
tree plantations in Dafeng farm of Hainan province were studied by Biolog-eco technique. The results indicated that:
the carbon metabolic activity of soil microbial increased with the extend of culture time，and its tend to was stable
after 144 hours. The utilization carbon capacity of soil microbial communities in rubber tree plantations was strong
for the sources of carboxylic acids，amino acids，amines and carbohydrates，but the capacity of using phenolic acids
and polymers was poor. The average well color development（ AWCD），Shannon-wiener index，McIntosh index
and capacity of utilization carbon source in tapping after（ November） were lower than those in indicated tapping
before（ May） . This that tapping caused the functional diversity of soil microbial carbon metabolism of rubber tree
plantations decreased.There were differences of average well color development（ AWCD），Shannon-wiener index，
McIntosh index and capacity of utilization carbon source at different ages of rubber tree plantations in tapping before
and after. |
