【摘要】 根据森林资源清查以及生物量转换因子法计算的森林碳汇量,选取造林面积、受害森林面积、森林病虫鼠害发生面积、木材产量以及营林基本建设投资完成额等指标作为森林碳汇量的相关影响因素,开展对辽宁、河北等20个省森林碳汇影响因素的灰色关联分析。结果表明:木材产量是最主要的影响因素,与其他指标相比较,营林基本建设投资完成额在促进森林碳汇量增长方面的作用相对较弱。更多还原

【Abstract】 As global warming is much concerned around the world, forest carbon sequestration becomes a hot topic among scholars domestic and abroad.Forest plays an irreplaceable role in regulating global carbon balance, reducing concentrations of greenhouse gases such as CO2 in the atmosphere, and slowing down global warming.According to the forest carbon sequestration calculated by methodology of biomass expansion factor based on forest inventory, this paper took afforestation area, the affected forest area, forest area with pests and rat disasters, timber output, and silvicultural capital construction investment as the influencing factor, to achieve gray incidence analysis on forest carbon sequestration of 20 Provinces.The conclusion is that timber output is the most important influencing factor, and compared with other indicators, silvicultural capital construction investment plays a relatively weak role in promoting the growth of forest carbon sequestration.更多还原
