Analysis on Tree Trunk Carbon Content Rate in Constructive Species of Main Forest Types in Garze
摘要
Abstract
The carbon content rate of tree trunks of six constructive species from different watersheds and different altitudes and different age groups in Garze was measured using the dry burning method,the change characteristics were analyzed to provide reference for the selection of tree species for afforestation in carbon sink projects.The results showed:the carbon content rate of tree trunks of the six constructive species were 49.00%,51.54%,49.66%,48.52%,47.60%,48.38%respectively in Picea likiangen-sis var.rubescens,Pinus densata,Larix potaninii,Juniperus tibetica,Populus davidiana,Betula platyphylla.The carbon content rate of tree trunk was higher than the reference value of Sichuan Province,but the difference was within 2.0 percentage points.The carbon content rate of tree trunk in the Jinsha River Basin was generally low,with no significant difference between it and the Yalong River Basin,and there was a significant difference between the Dadu River Basin and the Yalong River Basin and Jinsha River Basin.There were significant differences in tree trunk carbon content rate between young and mid-dle-aged and mature forests,and no significant differences between middle-aged and mature forests,indicating that trunk carbon content tends to stabilize with increasing age.There was a significant difference between the carbon content rate of tree trunk at low altitude and medium and high altitude,and no significant difference between medium and high altitude,indicating that the carbon content rate of tree trunk tends to be stabilized with increasing altitude.The research results can provide specific guidance for selecting suitable afforestation tree species and project inclusion periods based on different project boundaries when carrying out carbon sequestration afforestation projects in Ganzi Prefecture in the future,maximizing the carbon sequestration of afforestation projects.关键词
