云南省禄劝县森林碳储量分析

Analysis of Forest Carbon Storage in Luquan County of Yunnan Province

基于禄劝县第四次森林资源规划设计调查数据,利用生物量扩展因子法,从不同的林分、龄组、起源等方面对禄劝县森林植被碳储量进行估算。研究结果表明,禄劝县森林植被总碳储量为640. 2万t,其中乔木林分碳储量为614. 9万t,乔木经济林碳储量为10. 9万t,国家特别规定灌木林地碳储量为14. 3万t,竹林碳储量为0. 1万t,森林植被平均碳密度26. 4t·hm^(-2);天然林碳储量占林分总碳储量的91. 8%,中龄林碳储量占林分总碳储量的66. 7%,全县仍有较大的碳储备空间。

To acquire the forest carbon storage of Luquan County,based on data from the inventory for forest management planning and design,the forest carbon storage of Luquan County was estimated with variable biomass extension factor methed. The results showed that the total forest carbon storage of Luquan was 6. 402 million tonnes,the arbor forest carbon storage was 6. 149 million tonnes,the commercial forest carbon storage was 0. 109 million tonnes,the Bush forest was 0. 143 million tonnes,the bamboo forest was 1000 tons,and the average carbon density was 26. 4 t·hm^（-2）. The carbon storage of the natural forest and the middle-aged accounts for 91. 8% and 66. 7%,There is quite a large scale of cabon reserve in Luquan County.
