摘　　要：由大气CO2浓度不断增加引起的温室效应而导致全球气候变化对人类社会的可持续发展构成了巨大挑战,大气碳的减排增汇已经成为人类社会的共识。随着我国碳汇交易市场的发展和逐步健全,退耕还林碳汇效益的经济价值将会日益凸显。通过2000～2006年黔中清镇市红枫湖流域内退耕还林工程实施情况的调查,对林区内主要树种杉木、柳杉、桃树、李树、杏树、喜树、楸树7种林木的碳净贮量进行初步估算。随着时间的变化,森林的中、幼龄林碳贮量和碳密度都有上升的趋势,中、幼龄林将发挥越来越大的固碳潜力。通过对森林各树种蓄积量的预测,在所研究的7种树种中,杉木是研究区内碳汇功能强的树种,其次为柳杉,经果林的碳汇功能最弱,到2006年,其碳汇可达1.05×104kg,并根据模型估算,未来10年红枫湖流域的森林碳贮总量约为2.21×104kg,按每吨305元的价格计算,可产生7.17×106元的经济效益,固碳的经济效益十分可观。The increasing unceasingly of the global atmospheric CO2 concentration will lead to global climate change caused by the greenhouse effect of the atmospheric C02, which sharply challenges the sustainable development of the human society. Atmospheric carbon reduction has become the consensus of human society. As China＇s carbon sinks market development and gradually improvement, returning farmland to forest carbon sinks in the economic value of benefits will become increasingly prominent. In this study, the program of the returning farmland to forests were surveyed in the Hongfenghu Basin Drainage area,＇ mainly tree species in the region of Lin Chinese fir, cedar, peach, plum, apricot, camptothecin, such as seven kinds of bungei Carbon trees a preliminary estimate of net reserves during the time from 2000 to 2006. There would be 1.05x 104kg forest carbon storage in all of the Hongfenghu Basin Drainage during the next 5 years from 2000 to 2006. The carbon storage and carbon density of the forest, especially the young growth forest have an increasing trend with the plants growing time lengthened, and the young growth will play an increasing potential for the carbon sequestration. The volumes of the forest carbon sequestration were calculated through the trees on the forecast volume, the study in the seven kinds of trees, the fir is to examine the regional carbon sink function of strong trees, Japanese cedar, followed by fruit trees of the carbon sink function of the weakest. There would be 2.21×10^4kg forest carbon storage in all of the Hongfenghu Basin Drainage during the next 10 years, and would generate the economic benefits of 7.17 ×10^6 yuan according to the analysis on the economic benefits of the carbon sequestration by 305 yuan per a ton in prices.
