Origin-based biomass allometric equations, biomass partitioning, and carbon concentration variations of planted and natural Larix gmelinii in northeast China

Autor: Faris Rafi Almay Widagdo, Longfei Xie, Lihu Dong, Fengri Li

Publikováno v: Global Ecology and Conservation, Vol 23, Iss , Pp - (2020)

The area of larch (Larix gmelinii) plantations in northeast China has increased following the massive afforestation program implemented by China’s central government to provide biomass for global carbon sink and the development of industrial sector

Biomass Functions and Carbon Content Variabilities of Natural and Planted Pinus koraiensis in Northeast China

Autor: Faris Rafi Almay Widagdo, Lihu Dong, Fengri Li

Publikováno v: Plants, Vol 10, Iss 2, p 201 (2021)

The population of natural Korean pine (Pinus koraiensis) in northeast China has sharply declined due to massive utilization for its high-quality timber, while this is vice versa for Korean pine plantations after various intensive afforestation scheme

Climate change, especially modified courses of temperature and precipitation, has a significant impact on forest functioning and productivity. Moreover, some alterations in tree biomass allocation (e.g. root to shoot ratio, foliage to wood parts) mig

Biomass additivity is a desirable characteristic of a system of equations for predicting components and total biomass, since equations independently adjusted generate biologically inconsistent results. The aim of this study was to fit and compare thr

The introduction of an additive modeling method responsive to temperature and precipitation variables, and its applications to estimate the forest stand biomass of PICEA SPP. Of Eurasia

Autor: Shobairi, S. O. R., Usoltsev, V. A., Tsepordey, I. S.

Publikováno v: Applied Ecology and Environmental Research

This article was the first attempt of modeling changes in the additive component composition of 900 spruce stands’ (genus Picea sp.) biomass (t/ha), according to the trans-Eurasian hydrothermal gradients of Eurasia using the database compiled on th

Additive Models of Single-tree Biomass Sensitive to Temperature and Precipitation in Eurasia - A Comparative Study for Larix spp. and Quercus spp

Autor: Usoltsev, V. A., Shobairi, S. O. R., Tsepordey, I. S.

Publikováno v: Journal Of Climate Change

In the context of current climate change, it is important to know the patterns characterising the response of forest trees to the dynamics of air temperature and precipitation. In this study, the first attempt to model changes of additive component c

Additive biomass models for Quercus spp. single-trees sensitive to temperature and precipitation in Eurasia

Autor: Usoltsev, V. A., Zukow, W., Osmirko, A. A., Tsepordey, I. S., Chasovskikh, V. P.

Publikováno v: Ecological Questions

The analysis of the biomass of oak (genus Quercus spp.) trees on the aboveground component composition based on regression equations having the additive biomass structure is fulfilled. Two trends of changes in the tree biomass structure are revealed:
