如经选定，为了对伐木制品进行核算，对再造林土地上或选定的森林管理土地上碳储存变化的计算应基于以下方式：符合资格的森林中碳储存的增量总额减去土壤碳的任何变化量，减去伐木活动余下的碳储存，减去木材厂木渣的碳储存，减去用于造纸的木材产品、木屑或其他短生命周期木制品的碳储存，减去在承诺期生产但后又破坏的伐木产品的估计碳释放量，乘以从碳到二氧化碳的换算系数。

The land use pattern had changed by a relatively large margin in Neijiang city from 1997 to 2005. The main tendency of this change is that with remarkable reduction of cultivated land that decreased by 9936.11hm~2, unutilized land and water area, while garden land, forest land that increased by 7032.23 hm~2, grass land and building land increased notably. And during the research time, the speed of land use type change reduced from garden land, traffic land, forest land, residential areas and industrial and minings land, cultivated land, unutilized land to water area. The main trend of general dynamic degree changed from progressive increase to degression. From the analyses of land use diversion matrix, we know resulting in the quantity change of land use was that cultivated land being occupied by construction,adjustment in structure of agriculture and the implementation of the national reforesting formerly cultivated land policy in Neijiang city.
