摘要
为了探究江苏杨树人工林碳储量分布情况,利用2010年江苏省森林资源清查主要数据,分析了江苏杨树人工林空间分布格局以及碳储量、碳密度与区域社会经济状况之间的相关性。结果显示:江苏杨树人工林碳储量区域差异大;国民生产总值与碳储量间的相关关系说明,随着社会经济条件的增长,人工林碳汇能力迅速下降,经济发达地区对于人工林碳汇贡献很低;各地区林业生产总值与碳密度间的相关关系说明,林业生产总值较低和较高的地区杨树人工林碳密度都偏低。建议通过建立完善的区域及行业间生态补偿机制和更科学的森林经营措施保障杨树人工林可持续发展。
In order to analyze the carbon storage distribution of poplar plantation of Jiangsu Province, the data of forest re- sources assessment in Jiangsu Province（2010） was analyzed in this paper. The correlations between the spatial distribu- tion, carbon storage and density of poplar plantation and regional social economic status in Jiangsu Province were revealed. The results showed that there were large regional differences existing in the carbon storage of poplar plantation, and with re- gional social and economic developments, the carbon storage of poplar plantation declined sharply. The function relation- ship indicated that economical regions with poorer or better forestry produce had lower carbon density in poplar plantation. The possible solutions to existing issues on poplar plantation in Jiangsu Province included the establishment of ecological compensation mechanism among different regions and industries, and the improvement of forest management pattern.
