摘　　要：西部地区作为战略资源储备库和生态安全屏障,已成为我国发展森林碳汇的重要阵地。运用森林蓄积量扩展法研究发现,1994—2013年我国西部地区森林生物量碳汇量和森林碳汇总量均呈不断增长趋势,到2013年分别达42.4413亿t和103.5567亿t,预计到2015年西部地区森林生物量碳汇量将达40.8557亿t,碳汇潜力达1.5670亿t,到2020年西部地区森林生物量碳汇量达53.1227亿t,碳汇潜力达13.8339亿t,到2050年西部地区森林生物量碳汇量达60.0514亿t,碳汇潜力达20.7627亿t。但与国际平均水平相比,西部地区森林碳汇水平仍然较低,亟需通过提高碳汇林业的经营管理水平、构建西部森林碳汇市场体系、完善区域森林生态补偿机制和深化林业产权制度改革等途径提升西部地区森林碳汇能力。The forest is not only an important part of the earth＇s biosphere, but also an important regulator to maintain the balance of natural ecosystems. As an important strategic resource repository and ecological security barrier, the Western China has become one of important positions of forest carbon sinks. Using the forest stock volume expansion method, this paper estimated the amount of forest biomass carbon sinks and the aggregate amount of forest carbon from 1994 to 2013 in China＇s western region, the results showed that there were both growing trends for them, they were 42.4413 × 10^8t and 103.5567 × 10^8t until 2013. And the amount of forest biomass carbon sinks and the aggregate amount potential forest carbon sequestration will be 40.85574× 10^8t and 1.56704× 10^8t in 2015, 53.1227× 10^8t and 13.8339× 10^8t in 2020, 60.0514× 10^8t and 20.7627×10^8t in 2050, respectively. But compared with the international average, the western forest carbon sinks is still low, then there is absolutely a need for improving the forestry carbon sinks management level, building the western market system of the forest carbon sinks, improving the regional forest ecological compensation mechanism, deepening the reform of forestry property right system and so on, to further enhance the forest carbon sink capacity of the western region in China.
