Implications of allometric model selection for county-level biomass mapping [PDF]

Carbon Balance and Management, 2017
Background Carbon accounting in forests remains a large area of uncertainty in the global carbon cycle. Forest aboveground biomass is therefore an attribute of great interest for the forest management community, but the accuracy of aboveground biomass ...

Global patterns of allometric model parameters prediction [PDF]

Scientific Reports, 2023
Variations in biomass-carbon of forest can substantially impact the prediction of global carbon dynamics. The allometric models currently used to estimate forest biomass face limitations, as model parameters can only be used for the specific species of ...

Comparative Evaluation of Allometric, Machine Learning, and Ensemble Approaches for Modeling Dynamic Structure–Fresh Weight Relationships in Sweet Pepper [PDF]

Plants
Accurate fresh weight (FW) estimation is essential for growth monitoring and yield prediction in greenhouse fruit vegetables, but remains challenging due to the dynamic allocation between vegetative and reproductive organs.

Precise aboveground biomass estimation of plantation forest trees using the novel allometric model and UAV-borne LiDAR

Frontiers in Forests and Global Change, 2023
IntroductionPlantation forest is an important component of global forest resources. The accurate estimation of tree aboveground biomass (AGB) in plantation forest is of great significance for evaluating the carbon sequestration capacity. In recent years,

Logistic model outperforms allometric regression to estimate biomass of xerophytic shrubs

Ecological Indicators, 2021
Allometric model has been applied worldwide to estimate vegetation biomass for decades. However, this model fails to restrict the accelerating increase of biomass as body size grows. That contradicts to the size-related resource limits and intra-specific

Aboveground biomass estimation at different scales for subtropical forests in China

Botanical Studies, 2017
Background The accurate estimation of forest biomass at different scales is the critical step in the assessment of forest carbon stocks. We used three models at increasing scales: allometric model at ecoregional scale (model 1), dummy variable allometric

Pendugaan Cadangan Karbon Permodelan Penerapan Penanaman Asam jawa pada Jalur Hijau Jalan-jalan Tol Semarang-Solo

Al-Hayat, 2019
The increasing length of toll roads on the island of Java also increases the number of green lane that can be used for greening. One of the functions of the green road is for planting carbon-absorbing plants. Tamarind (Tamarindus indica) trees are a type
