摘　　要：根据重庆市2002年森林资源二类调查资料和重庆市2008年森林工程总体规划,估测出了重庆市森林植被的碳储量和碳汇量,并分析其地理分布情况和市域内不同林分的碳汇能力,对重庆市森林工程的碳汇潜力进行了预测.结果表明:重庆市(2002年)森林植被碳储量约为4 729万t,每年固定约397万t碳,折合1 454万t二氧化碳;重庆市东部地区的碳储量普遍高于西部地区,在各区县中碳储量排在前五位的分别是城口、巫溪、酉阳、石柱、奉节;重庆市域不同林分中,以马尾松的碳汇量最大,占重庆市总碳汇量的60%,其次是栎类,冷杉最少;重庆市森林工程造林成林后的森林碳汇价值高达36.65亿元/年,具有很大的碳汇潜力.Based on the data of Forest Resources Management Inventory in Chongqing in 2002 and the Forest Engineering Master Plan in Chongqing in 2008,the carbon storage and carbon sequestration of the forest vegetation in Chongqing Municipality are estimated,their geographical distribution and the carbon sequestration capacity of the different forest stand types in the municipality are analyzed,and the carbon sequestration potential of Chongqing forest engineering is predicted in this paper.The carbon storage of forest vegetation in Chongqing（2002） is 47.27 million t,and its carbon sequestration is 3.97 million t/a,being equivalent to 14.54 million t CO2.The carbon storage in the east of Chongqing is much more than that in the west of Chongqing.Of the Districts and Counties in Chongqing,Chengkou ranks the first,followed in sequence by Wuxi,Youyang,Shizhu and Fengjie.Of the different forest stand types in Chongqing,Pinus massoniana has the largest carbon sequestration,accounting for 60% of the total,Quercus ranks in the second,and Abies has the least carbon sequestration.After the establishment of the forests in the Forest Engineering Master Plan in Chongqing,the value of the carbon sequestration of the forest vegetation in Chongqing is estimated to be $3.665 billion per year.Thus,the carbon sequestration potential in Chongqing is considerable.
