选取林地面积、森林面积、造林面积、病虫鼠害防治面积等原有变量,采用因子分析法评价我国森林碳汇发展潜力,结果显示:森林资源总量因子是影响森林碳汇潜力最重要的因素,其次分别是森林生态建设因子、林业产业发展与投资因子以及森林灾害防治与气候因子。根据综合得分将全国31个省市区的森林碳汇发展潜力分为5个梯度,据此提出提高森林碳汇潜力的建议。
The author selected 14 original variables such as woodland area , forest area , afforestation area , controlling area of forest diseases, pests and forest rats and so on to evaluate forest carbon sequestration potential in China with the method of factor analysis. The author drawls the conclusion:he amount of forest resources is the most important factor that influences forest carbon sequestration potential, which is fol lwed by forest ecological construction factor, forestry industry development and investment factor, forest disasters prevention, control and climate factor. The 31 provinces, cities and autonomous regions are divided into five gradients according to the comprehensive score of forest carbon sequestration development potential. As a result, the author puts forward corresponding measures to improve forest carbon sequestration potential.
