广西钦州湾红海榄幼龄植株生物量相容性模型构建OA

In order to improve estimation accuracy of Rhizophora stylosa biomass,taking R.stylosa young plants collected from mangrove wetlands at Qinzhou Bay,Guangxi as research objects,based on selected biomass opti-mal independent model,two kinds of biomass compatible models were constructed using total control and com-ponents addition methods,and fitting and estimation effects of models were evaluated.Results showed that among independent models,w=aDbHc was optimal estimation model for R.stylosa components and total bio-mass,with R2 ranging from 0.765 to 0.934.R2 of two compatible models ranged from 0.766 to 0.956.Compared with corresponding total control compatible models and optimal independent models,components and total bio-mass of components addition compatible model had the highest R2 with total relative error more tending to 0%and the lowest root mean square error and mean absolute percentage error.Components addition compatible model had better fitting effect and higher estimation accuracy,which could be used as optimal model for R.sty-losa biomass estimation at investigation area.
