摘　　要：通过调查未经防治、经化学防治、物理机械防治和正常思茅松林分,测算了林木不同组分的生物量、含碳率和含碳量,并估算了4种思茅松林的BEF、生物量、碳储量、碳密度和碳汇功能。结果表明,景谷县思茅松人工林林木生物量、林木碳储量、土壤碳储量、林分总碳储量分别为1.51×107、7.83×105、1.42×106、2.28×106t,表现出巨大的碳汇;4种林分思茅松的BEF在0.94~1.00;思茅松不同组分生物量、碳储量的分配为干〉根〉枝〉叶;林分有机碳的分配为土壤层〉林木层〉枯落物层〉灌木层〉草本层。松毛虫危害后,每株总生物量、每株碳储量、林分碳密度、土壤碳密度分别降低15.80 kg、8.10 kg、47.04 t/hm2、32.66 t/hm2,通过化学/物理机械防治后分别提高9.70 kg/6.90 kg、5.00 kg/3.62 kg、25.93 t/hm2/19.50 t/hm2、17.93 t/hm2/13.09 t/hm2。Through surveying the standing forest of Pinus kesiya var langbianensis under different conditions,namely,without control,chemical control,physical and mechanical control as well as normal one,the biomass,carbon rate and carbon content of different components of P.kesiya var langbianensis were determined,moreover,BEF,biomass,carbon storage,carbon density and carbon sink function of 4 kinds of forests were estimated.The result showed that the tree biomass,carbon storage of the tree,the soil and the forest in Jinggu County were 1.51×107,7.83×105,1.42×106 and 2.28×106 t,respectively,these data showed carbon sink function of P.kesiya var langbianensis forest was strong;BEF of the 4 kinds of forests are from 0.410 2 to 1.250 0;the biomass and carbon storage of different components from high to low were：trunk root branch leaf;the organic carbon storage of the forests from high to low were：soil horizon woodyard litter layer bush layer field stratum.The tree biomass and carbon storage,carbon density of the forest and the soil dropped 15.80 kg,8.10 kg,47.04 t/hm2 and 32.66 t/hm2,respectively after Dendrolimus kikuchii Matsumura was harmed.They raised 9.70 kg/6.90 kg,5.00 kg/3.62 kg,25.93 t/hm2/19.50 t/hm2 and 17.93 t/hm2/13.09 t/hm2,respectively after the forests were controlled by chemical or physical ways.
