摘要
本研究以处于同一气候区内两种温带树种(白桦和硬阔叶林)为研究对象,采用样地清查和异速生长方程法量化两种林型的碳密度和分配,并评价其固碳能力。林龄相近的林型,所处的立地条件和林分组成不同,利用胸高断面积标准化后发现差异显著。对我国东北典型温带森林碳密度和碳汇功能进行了系统的研究,为区域森林碳循环的构建和校验提供了重要的实测数据,也为东北地区碳汇林业提供了科学依据。
In this study, we investigated two representative temperate forests under same climate conditions in northeastern China. The aims of this stud were to measure C density, net primary production （NPP） and their distribution patterns so as to assess C sequestration capacity of the forests with forest inventory and allometry approaches. Close to the forest stand age, in which the composition of different site conditions and stands, standardized by basal area and found significant differ- ences. This comprehensive investigation on forest C density and sink strength provides important data for developing and validating C cycling models for the temperate forests, and scientific basis for forest C sequestration management in this re- gion.
