- The East China belongs to the area of the high value (over (3t/hm~2)) and the agropastural ecotone in North China has the low value of carbon density which is less than (1t/hm~2). 农田C密度高值区主要分布在我国东部地区且多>3t/hm2;低值区主要分布在我国北方农牧交错带地区且普遍<1t/hm2。
- 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. 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
