县域森林经营增汇减排发展路径研究——以浙江省临安区为例

The Discussion on the Development Path to Increase Carbon Sink and Reduce Carbon Emission Forest Management at County Level--A Case Study in Lin’an of Zhejiang Province

以浙江省杭州市临安区森林经营为例,从森林培育增汇和森林经营减排两方面入手,运用定量和定性分析相结合的方法,计算与分析在县域森林经营中森林增汇与减排的主要方式、所占权重以及在增汇方式中单位面积的增汇能力。结果表明:县域森林经营中在保护森林土壤为前提下,到2020年12月临安区森林培育增汇量排序为封山育林>森林抚育>林分改造>更新造林;单位面积增汇能力排序为更新造林>林分改造>森林抚育>封山育林;森林经营减排重要程度排序为森林低碳经营>林业循环经济>低碳森林旅游。以此设计县域森林经营增汇路径和森林经营减排路径,提出应用区位、主要措施、发展建议。

This paper takes the forest management of Lin’an in Zhejiang Province as an example to calculate and analyze the main mode,the weight and the increasing capacity in per unit area of increasing carbon sink and reducing carbon emission in county areas through using the combination of quantitative and qualitative analysis.The results show that based on the premise of the soil protection,the carbon sink increase of Lin’an by 2020 is sorted as follows:closed forest>tending of woods>stand improvement>reforestation.The increasing capacity of carbon sink per unit area is sorted as follows:reforestation>stand improvement>tending of woods>closed forest.The importance of reducing carbon emission in forest management is sorted as follows:low-carbon forest management>forestry circular economy>low-carbon forest tourism.Based on the results,the paper designs methods to increase carbon sink and reduce carbon emission in county areas and proposes application locations,main measures and development suggestions.
