杉木林分经营碳汇项目发展的潜力分析

Potential Analysis of Launching Forest Management Carbon Sequestration Projects by the Management of Chinese Fir Forest

为了科学评价利用福建省杉木林分资源开展森林经营碳汇项目的潜力,运用《森林经营碳汇项目方法学》提供的生物量方程法,以森林资源建档数据为数据源,参考全国碳汇交易价格,结合省内FFCER项目实践,估算了未来十年福建省杉木林分的森林经营碳汇总量和价值量,分析了影响森林经营碳汇项目经济收益的主要因素。结果表明:福建省杉木林分森林经营碳汇总量达7.02×107 t,碳密度为7.7 t·hm-2,可生成森林经营碳汇项目176个,保守估算价值量为17.56亿元,各设区市发展潜力差异较大。森林经营碳汇项目的收益率受碳汇交易价格、经营管理决策以及不同地区的林地质量等因素的综合影响。

In order to evaluate the potential of launching forest management carbon sequestration projects by the management of Chinese fir forest in Fujian province,quantity and value of carbon sequestration could be supplied in the following 10 years were calculated according to the annual forest resource data and average price that had been traded.Relevant factors were also analyzed.Results showed that the total amount of carbon sequestration of Chinese fir forest in Fujian province could reach to 7.02×107 t and the carbon density could be 7.7 t·hm-2,176 forest carbon sequestration projects could be generated,and economic value could be more than 1.756 billion yuan.In practice,the benefit of the forest carbon projects could be influenced by trading price,decisions made by forest owners and also the management techniques of different areas.
