基于森林资源二类调查数据的重庆市森林碳储量估算研究

Estimating Carbon Storage of Chongqing's Forests Based on Forest Inventory Data

根据重庆市2010年森林资源规划设计调查数据资料,采用森林蓄积量扩展法等对重庆市森林植被碳储量进行了分析研究。结果表明:重庆市森林植被碳储量达15 918.95万t,折合CO2约为58 422.55万t。其中乔木林碳储量为13 697.22万t,占总碳储量的86.04%;乔木经济林75.12万t,占总碳储量的0.47%;竹林1 838.23万t,占总碳储量的11.55%;国家特别规定灌木林308.38万t,占总碳储量的1.94%。表明重庆市森林碳储量较大,碳汇能力强。

According to forest resources planning and design survey data in Chongqing in 2010, the forest stand volume expansion method was used to study and analyze the carbon storage of forest vegetation in Chongqing. The results showed that, Chongqing forest vegetation carbon storage reach up to 159.19 million tones, equivalent to CO2 about 584.23 million tones. In which, the carbon storage of arbor forest is 136. 97 million tones, accounting for 86.04% of the total carbon storage, the carbon storage of economic forest is 0.75 million tones, accounting for 0.47% of the total carbon storage, the carbon storage of bamboo is 18.38 million tones, accounting for 11.55% of total carbon storage, and the carbon storage of national special provisions shrubbery is 3.08 million tones, accounting for 1.94% of the total carbon storage. So, the forest carbon storage in Chongqing showed greater carbon sequestration and carbon sequestration ability.
