上杭县森林碳储量估算与动态分析

该文以上杭县2002年、2014年两期森林资源二类调查为基础,结合不同森林类型生物量和蓄积量的回归方程,对上杭县森林植被碳储量和碳密度进行了估算与动态变化分析。结果表明,2002—2014年期间,上杭县森林碳储量有所增多,森林碳密度由26.5t·hm-2增至33t·hm-2,森林碳储量年龄结构动态变化中,幼龄林的碳储量有所降低,碳密度有所下降,表明总体森林资源保护较好,但幼龄林的林分质量有待于提高。

Estimating and Dynamic Change Analysis of Forest Carbon Storage in Shanghang County

Based on the investigation of two kinds of forest resources in Shanghang County in the year of 2002 and 2014,the carbon storage and carbon density of forest vegetation in Shanghang County are estimated and their dynam?ic changes are analyzed,with the method of regression equation between stand biomass and volume in different forest types.The result show that forest carbon storage has been increased in Shanghang County since 2002 to 2014,forest carbon density increased from 26.5t·hm-2 to 33t·hm-2,dynamic changes in the age structure of forest carbon storage show that young forest carbon storage was decreased and carbon density was decreased,this result implied that the overall forest resource protection is better,but the young forest stand quality needs to be improved.
