五指山市森林碳储量及碳密度异质性初步分析

Preliminary analysis on forest carbon storage and carbon density heterogeneity in Wuzhishan

以五指山市森林植被为研究对象,利用森林资源清查的相关数据,采用生物量换算因子连续函数法,估算出五指山市森林碳储量及碳密度,并对不同林种和不同森林类型的碳储量和碳密度进行初步研究。结果表明:五指山市森林植被总碳储量为6.0609Tg,平均碳密度为52.22t/hm^2。不同森林林种碳储量为:防护林>特种用途林>用材林>经济林,其碳密度大小顺序相同;不同森林类型碳储量为:常绿雨林>经济林>常绿阔叶林>针叶林>落叶阔叶林>灌木林>竹林;碳密度为:常绿雨林>落叶阔叶林>针叶林>常绿阔叶林>经济林>灌木林>竹林。

According to the Second Class Forest Resource Inventory data of wuzhishan in2010,using the amount of conversion factor function estimated forest carbon storage and carbon density of Wuzhishan.And the carbon storage and carbon density of different forest species and different forest types were analyzed.The re-sults show that the number of total carbon storage is6.0609Tg,the average carbon density is52.22t*hm"2.The carbon storage in different forest species distribution is that Shelter forestwSpecial purpose forestwTimber for-est>Economic forest,as the same as carbon density;carbon storage in different forest types distribution is that Evergreen rainforestWeconomic forestWevergreen broad-leaved forestWconiferous forestWdeciduous broad-leaved forestWshrub forestWbamboo forest;carbon density is that Evergreen rainforestWdeciduous broad-leaved forestW coniferous forestW evergreen broad-leaved forestW economic forestW shrub forestW bamboo forest.
