Description

Technical Field

[0001] The invention belongs to the field of tree carbon reserve calculation, and in particular relates to a single tree carbon reserve calculator based on multi-parameter fusion. Background Art

[0002] Estimation of biomass carbon storage is a key step in scientifically understanding the carbon sink function of forests and is also one of the foundations for formulating climate change response strategies. As the basic unit of forest ecosystems, individual trees are the core carriers for maintaining carbon sink balance, biodiversity and ecological service functions. The synergistic and superimposed effects of their individual functions ultimately drive forests to become complex life networks with ecological resilience, environmental services and sustainable development capabilities.

[0003] The measurement methods of biomass carbon storage mainly include traditional measurement methods (actual measurement method and carbon storage model estimation method) and remote sensing estimation method. Among them, the actual measurement method can directly obtain the carbon allocation data of each organ, but it is extremely destructive and requires cutting down standard trees for laboratory measurement of carbon allocation data of each organ, which is costly and time-consuming; the carbon storage model estimation method is a method that uses a pre-established carbon storage regression model and uses forest parameters such as breast diameter (DBH) and tree height (H) and carbon content to calculate the biomass carbon storage of the target tree species. Compared with the actual measurement method, it reduces damage to the environment, is easy to operate, and has low cost. The model library covers common tree species and is more suitable for situations with small measurement areas and high accuracy requirements; the remote sensing observation method can perform high-precision vegetation carbon storage inversion over a large area through optical remote sensing, radar remote sensing and other technologies. It has become the main technical means for estimating forest ground carbon storage at a regional scale.

[0004] At present, the research on vegetation biomass carbon storage is common in sheet afforestation or large-scale afforestation, and the biomass carbon storage of individual trees is rarely measured, and most of them are concentrated on the research of technology and methods. There is less research on concise and practical calculation software or products, and there is a lack of research and development of related products. Based on the characteristics of each measurement method for individual trees and forest biomass carbon storage, the present invention selects the carbon storage model estimation method as the main technical basis, collects the one-dimensional and two-dimensional carbon storage models of common tree species in China, and combines the aboveground biomass carbon content and underground biomass carbon content of trees to provide a single tree carbon storage calculator based on multi-parameter fusion, aiming to improve the calculation efficiency of single tree biomass carbon storage.
