摘 要:全球气候变暖是当前人类面临的最大环境问题之一,也是21世纪人类共同面临的严峻挑战,森林的碳汇作用对全球的气候变化有很大程度的影响,森林可以固定大气中的CO2,同时释放出O2,碳汇是森林生态系统的重要功能。本文依据不同乔木树种密度系数的差异,把大青山乔木分为针叶树和阔叶树,对大青山自然保护区乔木林的碳汇效益进行了计量,计算出了不同乔木树种各龄级的单位面积蓄积量及生物量,主要乔木树种固碳总量为1 235498.00t,释氧总量为909 569.08t;大青山主要乔木树种总的固碳价值为1.5×109元,总的释氧价值为9.1×108元。It is the biggest environment problem that the global climate becomes more and more warmer and it is the Challenge of mankind in the 21st century.The role of carbon sink of the forest will have great impact to global climate change.The forest can fix CO2 and at the same time can release O2 in the atmosphere.Carbon sequestration is an important function of forest ecosystems.The trees of Daqing mountain is divided into coniferous trees and broadleaf trees based on density factor of the different trees.The benefit of carbon sequestration has been measured about the arbor of Daqing mountain.The volume per unit area and biomass of the different tree species in each age-class has been calculated.The amount of carbon sequestration is 1235498.00t and the oxygen release total 909569.08t.The main tree species of Daqing mountain in the total value of carbon is 1.5×109 yuan,the total value of release oxygen is 9.1×108 yuan.
