利用浙江省设立的火炬松样地资料,建立火炬松人工林立地指数模型、生长收获模型、生物量模型等,区分不同立地条件、采用定量方法,并考虑间伐因素,建立了浙江省CDM-ARP火炬松林碳汇监测方法学,对火炬松林分碳密度、碳储量和CO2净吸存量进行监测。监测方法分为项目规划阶段(造林前)预测和林分生长阶段(造林后)监测。选择易测定的碳库作为监测对象,并用常规测树因子来估测较难测定的各器官生物量,用生物量法估算碳汇量。
Based on the data of the Pinus taeda in Zhejiang Province, this paper established the site index model, the growth and harvest model, the biomass model of Pinus taeda plantation to distinguish different site conditions, and adopted the quantitative method and considering the thinning factors to establish the CDM-ARP Pinus tabulaeformis forest carbon sink monitoring methodology, the Pinus densiflora forest carbon density, carbon storage and net CO2 inventory were monitored. The monitoring methods are divided into the project planning stage (pre-afforestation) and the stand growth stage (afforestation) monitoring. The carbon stocks which are easy to be measured are selected as the monitoring objects, and the conventional measurement of tree factors is used to estimate the biomass of each organ which is more difficult to be measured, and the biomass is used to estimate the carbon sinks.
