摘要
依据信阳市森林资源清查数据及河南鸡公山森林生态站长期连续观测数据,对2012年信阳市森林生态系统固碳释氧生态效益进行了评估.结果表明,2012年信阳市森林生态系统年固碳量为318.61万t、释氧量744.98万t,其生态效益总价值为107.95亿元.不同林分类型评估表明,杨树提供的固碳释氧生态效益最大,为52.42亿元;其次是马尾松林,为27.02亿元;软阔类最小,为0.93亿元.
The ecological benefit of forest carbon fixation and oxygen released in Xinyang were evaluated in 2012 based on Xinyang forest resources inventory data and Henan Jigong mountain forest ecological station long-term continu- ous observation data. The results showed that the total annual amount of carbon sequestration was 3. 186 1 million ton, amount of oxygen released was 7. 449 8 million ton, value of the ecological effect was 10.795 billion yuan（RMB） . E- valuation of ecological benefit of different forest type showed ： benefit of populus tremula was greatest, value of 5. 242 billion yuan, then the pinus massoniana forest, value of 2. 702 billion yuau, and soft broad-leaved forest is smallest, value of 0. 093 billion yuan.
