湖南4种森林生态系统碳汇功能研究
|
摘要
通过对组成长沙城市森林中4种主要森林类型的碳汇功能进行初步研究、对比分析和评价,得出以下结论:4种森林生态系统固定二氧化碳的能力为586.24 Tg.湖南省城市森林固碳能力中起主要作用的是针叶林,阔叶林虽然具有较强的固碳能力,但由于其在面积上的劣势,不是湖南省森林碳储量的主要来源,4种森林生态系统碳储量的排列顺序为:马尾松(211.67 Tg)、樟树(194.91 Tg)、杉木(169.85 Tg)、枫香(9.81 Tg).
Based on the data of forest inventory,the carbon storage of 4 forest ecosystems in Hunan provice are studied,contrasted and evaluated.The results are as follows:the total carbon storage of 4 forest ecosystems is 586.24 Tg.The main carbon storage is conifers ecosystem in Hunan and there is a smaller carbon storage about broadleafs because of little areas.The sequence of 4 forest ecosystems carbon storage is:Pinus massoniana Lamb(211.67 Tg)、Cinnamomum camphora(194.91 Tg)、Cunninghamia lanceolata Hook(169.85 Tg)、Liquidambar formosana Hance(9.81 Tg).
