Standing wood biomass model and carbon measurement parameters---栎树
1 Scope
This standard specifies the standing biomass model of Eucalyptus (Quercusspp.) and its compatible biomass conversion factor function, rhizome ratio
Number and carbon factor, etc.
This standard applies to the measurement and monitoring of biomass and carbon storage of eucalyptus forests in China.

3 Terms and definitions
The following terms and definitions apply to this document.
3.1
Standing timber biomass treebiomass
The total dry weight of organic matter present in the standing timber at a certain moment, the biomass on the ground and the underground biomass, using the MA and MB tables, respectively.
Show. Among them, the aboveground biomass includes four components. trunk (peeling), bark, branches (including fruit), and leaves (including flowers); underground biomass includes rhizomes,
Rough roots (diameter ≥ 10mm) and fine roots (2mm ≤ diameter < 10mm), roots below 2mm in diameter are not included in root biomass and are included in soil
Soil organic matter content.
3.2
Biomass conversion factor biomassconversionfactor
The ratio of biomass to standing timber in forest trees (g/cm3 or t/m3), expressed in BCF. According to this parameter, the standing timber product V can be
(10-3m3) is converted to aboveground biomass MA (kg). When the biomass conversion factor is not constant, along with the tree diameter D (cm) and tree height H (m)
When changing, the relationship between the biomass conversion factor and the DBH and tree height of the forest is called the biomass conversion factor function.
3.3
Rhizome than root-to-shootratio
The ratio of forest underground biomass to aboveground biomass, expressed in RSR. Based on this parameter, underground organisms can be estimated from above-ground biomass MA.
The amount of MB is obtained to obtain the whole tree biomass. When the rhizome ratio is not constant, the root-to-stem ratio and the forest will vary with the DBH and tree height H of the forest.
The relationship between the DBH and the tree height is called the rhizome ratio function.
3.4
Wood density wooddensity
The mass per unit volume of wood (g/cm3 or t/m3), expressed in WD. Usually divided into full dry density, air dry density and basic density, here
The basic density of the trunk (including wood and bark), that is, the ratio of the trunk dry mass to the trunk volume.
