摘　　要：本文以湘西自治州青坪林场27年生的光皮树人工林为研究对象,对其增汇减排效果进行了研究。结果表明:(1)27年生的光皮树人工林目前仍处于较高碳汇集状态,即增汇状态。它的总碳汇量的积累随着标准木总生长量(即生物量)的变化而变化。(2)27年生的光皮树人工林每年每1 hm2可减少CO2排放量51.48 t,按照10%面积(2 200万hm2石灰岩山地)栽植光皮树,成年后可每年减少CO2排放量11.33亿t。The effects of the fixed carbon and reducing discharge of 27-year-old Comus wilsonlana plantation Qingping Forest Farm, Xiangxi Autonomous Region were studied. The results showed that, （ 1 ） 27-year-old C. wilsoniana plantation were in much higher carbon storage. And its accumulation of whole carbon storage changed with total increment （biomess） of typetree. （2） 27-year-old C. wilsoniana plantation reduced the emission of CO2 51.48 t/hm2 every year. If according to planted C. wilsoniana in 10% of areas （ 2. 2 x 107 m2 of lime stone area） which could reduced emission of CO2 11.33 x l0s t every year in its old years.
