摘要/Abstract

摘要： 提高森林生态系统C贮量的估算精度,对于研究森林生态系统向大气吸收和排放含C气体量具有重大意义.中国的森林生态系统植物C贮量的研究刚刚开始,由于估算方法问题,不同估算结果存在着较大的差异.本研究以各林龄级森林类型为统计单元,得出中国森林生态系统的植物C贮量为3.26～3.73Pg,占全球的0.6～0.7%;各森林类型和省市间有较大的差异.森林生态系统植物C密度在各森林类型间差异比较大,介于6.47～118.14Mg·hm^-2,并且有从东南向北和西增加的趋势.这种分布规律与我国人口密度的变化趋势正好相反,两者有一种对数关系.这说明我国实际森林植物C密度大小首先取决于人类活动干扰的程度.

Abstract: To improve the estimatation of carbon pool of forest ecosystems is very important in studying their CO₂ emission, uptake. The estimation of vegetation carbon pool in China has just begun. There is a significant difference among estimates from different methods applied. Based on forest inventory recorded by age class, the vegetation carbon storage of forest ecosystems in China was estimated to be 3.26～3.73Pg, accounting for 0.6～0.7% of the global pool. The carbon densities were difference among forest types, provinces, in range of 6.47～118.14Mg·hm ^-2 .There is an incremental tendency from southeast to north, west. This trend is negatively related with the change in population density in logarithmic mode, which indicates that the actual forest carbon density is prominently determined by human activities.
