第二代桉树人工纯林和混交林土壤呼吸及其组分研究
以广西凭祥中国林业科学研究院热带林业实验中心第二代桉树人工纯林（PP2）及其与降香黄檀混交的混交林（MP2）为研究对象，采用壕沟法，利用LI-8100土壤呼吸测定系统，对两种林分土壤呼吸组分进行分离研究。结果表明：PP2和MP2土壤呼吸速率及其各呼吸组分季节变化与土壤5cm处的温度季节变化相似，峰值出现在6---8月份，谷值出现在12月底至次年1月初，土壤呼吸速率与土壤含水量无关；PP2全年土壤总呼吸为1147．41g·m^-2，比MP2（844．07g·m^-2）增加了26．44％，MP2的自养呼吸（RR）累积量（136．87g·m。）比PP2（506．72g·m12）降低72．99％，而其...

| Notes | 11-1221/S Eucalyptus plantation, nitrogen-fixing species, soil respiration, autotrophic respiration, heterotrophic res- piration In order to determine the seasonal pattern of respiration and elucidate the contribution of respiration com- ponents and their control factors in Eucalyptus plantations, comparative experiments and the trenching plot method with LI-8100 automated CO2 flux system were used to quantify the components of soil respiration in three-4-year-old second rotation pure plantations （PP2） of Eucalyptus and three 4-year-old second rotation mixed Eucalyptus urophyl-la and Dalbergia odorifera plantations （MP2） in Guangxi Zhuang Autonomous Region, southern China. The results showed that there were similar seasonal dynamics for the respiration and its compoments in both the plantations. Thetotal respiration （Rs ）, heterotrophic respiration （RH） , and autotrophic respiration （RR ） varied markedly during the year with the highest rates between June to August, and the lowest rates between December to Janu |
