2006—2016年昆明市西山林场森林资源碳储量动态分析

Dynamic Analysis on Carbon Storage of Forest Resources in Xishan Forest Farm of Kunming from 2006 to 2016

基于2006年、2016年森林资源调查数据,运用生物量扩展因子法估算乔木林各优势树种(组)生物量,并根据生物量和含碳系数的大小,计算碳储量、碳密度,藉此对不同优势树种(组)、不同起源林分、不同林龄林分、不同类型林分碳储量、碳密度进行了比较分析。结果表明,10年间昆明市西山林场森林面积、蓄积增加151hm^2、58060m^3;碳储量增加了25230.64 t,达到111530.27 t,比2006年增加了23%。碳密度随林龄的增加而增加。

Based on the investigation data of forest resources in 2006 and 2016,the biomass expansion factor method was used to estimate the biomass of each dominant tree species(groups)in arbor forest,and the carbon storage and carbon density were calculated according to the size of biomass and carbon coefficient,so as to compare and analyze the carbon storage and carbon density of different dominant tree species(groups)and different types of stands with different origins and different ages.The results showed that the forest area and stock volume of Xishan Forest Farm increased by 151 hm^2 and 58060 m^3 respectively,and the carbon storage increased by 25230.64 t to 111530.27 t,23%more than that in 2006.The carbon density increased with the increase of forest age.
