苍溪林业碳汇能力及价值研究

A Study of the Ability and Value of Carbon Sequestration of Forestry in Cangxi County

CO2是工业和化石燃烧的排放气体,不断加剧温室效应,森林大量吸收固定大气中CO2,成为巨大的碳汇。为减缓不断加剧的全球气候变化,林业正在经历发展方向的调整与转变,固碳林业悄然兴起,包含碳汇造林、保护森林碳库、发展低碳经济和碳替代措施等4个方面。在唱响"生态家园",发展绿色GDP的目标下,摸清当地碳汇能力,开展碳价值测算,为低碳经济发展和保护碳库起着十分重要的作用。本文以四川省苍溪县为例,开展林业碳储量、固碳能力、固碳潜力及固碳价值的测算和研究,为今后绿色GDP计量、发展低碳经济、碳汇融资提供科学依据。

CO2 ,the exhaust gas from industry and fossil combustion, is gradually intensifying the green- house effect. However, forests absorb and fix a great quantity of CO2 in the air, and become a huge carbon sink. In order to slow down the intensifying global climate change, forestry is just experiencing the adjust- ment and changes of its development direction, and the carbon forestry,which includes four aspects：car- bon sequestration forestation, forest carbon sink protection, low-carbon economy development and carbon alternatives, is quietly emerging. With the objective of claiming ＂ecological homestead＂ and developing green GDP, investigating the local carbon sequestration ability and calculating the carbon value play a ver- y important role in developing the low-carbon economy and protecting the carbon sink. This article takes Cangxi county in Sichuan province as an example to calculate and research the forest carbon storage, car- bon sequestration ability, carbon sequestration potential and carbon sequestration value, and provides sci- entific basis for the future green GDP measurement,low-carbon economy development and carbon sink fi- nancing.
