摘要：该文在建立杉木人工林生物量和生产力数据库基础上,分析了区域尺度杉木人工林生物量、生产力、各器官分配比例及其与林龄的关系。结果表明,区域尺度杉木人工林总生物量和林龄之间有很好的相关性,可用Chapman-Richards生长方程表达;利用森林资源清查中的蓄积量数据计算的各龄级生物量比实测数据更能代表林分的实际平均生长情况;各器官生物量分配比例随林龄的变化规律因器官而不同;杉木人工林平均生产力的变化趋势落后于连年生产力近十年,因此使用平均生产力并不能真正代表杉木人工林每年的实际生产力变化情况。此结果为第二次土地利用变化和林业温室气体清单的编制提供了基础数据,以提高中国林业温室气体清单编制的质量。
Based on the Chinese Fir plantation biomass and productivity database, we analyzed the biomass, productivity, allocation rate of various organs in the Chinese Fir plantation, the relationship between the stand age and the biomass, productivity, allocation rate of various organs on the region scale. Results show that there is a significant relativity between the gross biomass of the Chinese Fir plantation and the stand age on the region scale. This relationship can be expressed by the Chapman-Richards growth equation. The biomass of every age calculated using the volume data in the forest inventory material is better than the biomass data measured in the experimental site in representing the actual growth situation of Chinese fir plantation. The biomass distribution rate of various organs is different with the stand age. The change trend of average productivity with the stand age is about ten years later than that of year-by-year productivity. So, the average productivity can not represent the yearly actual productivity change of the Chinese fir plantation. These results can provide some datum for the second national Greenhouse Gas Inventory and improve the quality of the Inventory.
