AI Technical Summary

Technical Problem

The existing mangrove biomass model is difficult to accurately estimate the biomass of artificially constructed young mangroves, especially in Guangdong, and sampling of underground biomass is difficult. The existing model lacks research on underground biomass.

Method used

By measuring the base diameter and plant height of mangroves, a power function and linear function model between the above-ground and underground parts of biomass and base diameter and plant height is constructed, providing a fast and accurate estimation method.

Benefits of technology

The rapid and accurate estimation of the above-ground and underground biomass of young mangroves artificially created is achieved, filling the gap in the existing model's estimation of young mangroves and improving the accuracy of the estimation.

Abstract

The invention discloses a method for estimating overground and underground biomass of mangroves of different young ages artificially built in Guangdong province. Base diameters D, plant heights H, overground part biomass and underground part biomass of red sea olive, avicennia marina, aegiceras corniculatum, kandelia candel and bruguiera gymnorrhiza are collected, D and H parameters are utilized to construct five mangrove plant biomass prediction models, D and H can derive a plurality of compound variables DH, D2H and DH2, and a single or compound variable is used as an independent variable to predict overground and underground biomass of mangrove plants. Constructing a power function model and a linear function model between the biomass of the overground part and the underground part and the base diameter and the plant height; according to the different-speed growth equation of the Guangdong artificially-built young mangrove, the biomass of the large-area artificially-built young mangrove can be quickly and accurately estimated by measuring tree measuring factors such as the height and the base diameter of the mangrove, and the blank of biomass estimation of the artificially-built young mangrove at present is filled.
