东北东部年龄序列次生林碳通量格局
The pattern of carbon flux in age-series secondary forests in northeast,China
[目的]本文旨在量化温带森林恢复进程中土壤呼吸及其分配,比较干扰后碳汇年龄效应。[方法]本研究以东北帽儿山干扰后形成的年龄系列次生林为研究对象,包括林木采伐一次近熟林(NS,林龄 64年)、采伐两次中龄林(MS,林龄 32 年)、采伐两次幼龄林(YS,林龄 9 年),采用森林清查和异速生长方程结合的方法,得到生态系统及各组分净初级生产力(NPP),利用LI-8100A CO2/H2O分析仪于 2021年 5 月开始至生长季结束每半个月测定土壤呼吸…查看全部>>
[Objective]The study is to quantify soil respiration and its allocation during the restoration process of temperate forests,and to compare the post-disturbance carbon sink age effect.[Method]In this study,we used the age series of secondary forests formed after the disturbance of maoershan area,northeast of China,including forests harvested once for near-mature forest(NS,64 years old),harvested twice for middle-aged forest(MS,32 years old),and harvested twic…查看全部>>
