Abstract

The invention discloses a biomass modeling method for a man-made forest. The method comprises a step of standing tree biomass measurement and water content measurement, and the step comprises the substeps: felled tree selection, sample plot setting and surveying, sample tree felling, data recording and calculation. According to the characteristics of the common man-made forest resources in the Hainan Province, main trees in a tropical man-made forest in the Hainan Province are selected, and the method employs a full harvesting method according to different ages, diameter class and site conditions, collects the biomass data, obtains the biomass samples, and carries out the biomass modeling of the man-made forest, so as to provide data support for the completion of the measurement of the carbon reserve of the whole Hainan island and provide basis for the evaluation of the structure and functions of a regional ecological system.

Description

technical field [0001] The invention belongs to the technical field of forestry, and in particular relates to a method for modeling planted forest biomass. Background technique [0002] Forest biomass and carbon storage are the main indicators for evaluating forest carbon sink capacity, while the standing tree biomass model, biomass conversion factor, root-to-shoot ratio function, and carbon coefficient are the basis for the measurement of forest biomass and carbon storage. In order to establish national forest biomass and carbon storage measurement standards and enhance my country's forest carbon sequestration monitoring capabilities, starting from the eighth national forest resource inventory in 2009, the Resources Department of the State Forestry Administration has made great efforts to promote the biomass survey and modeling of major tree species in my country. As of 2013, more than 20 million yuan has been invested, and the sample collection and parameter determination ...
