A Bayesian Approach to Estimating Seemingly Unrelated Regression for Tree Biomass Model Systems
Bayesian approaches seemingly unrelated regression Korean larch Markov chain Monte Carlo Gibbs sampler
2024/1/19
Accurate estimation of tree biomass is required for accounting for and monitoring forest carbon stocking. Allometric biomass equations constructed by classical statistical methods are widely used to p...
Modeling the Carbon Cycle of a Subtropical Chinese Fir Plantation Using a Multi-Source Data Fusion Approach
process-based terrestrial ecosystem model model–data fusion multi-source data carbon cycle plantation
2024/2/5
Process-based terrestrial ecosystem models are increasingly being used to predict carbon (C) cycling in forest ecosystems. Given the complexity of ecosystems, these models inevitably have certain defi...
Adaptive k-tree sample plot for the estimation of stem density: An empirical approach
plotless sampling distance sampling bias efficiency forest sampling
2018/3/6
Available budgets for the inventory of non-commercial woodlands are small. Therefore, there has been increased
interest in using distance methods, such as k-tree sampling, which are faster than fixed...
GIS APPROACH TO LANDSCAPE EVALUATION BASED ON SMALL WATERSHED UNITS
GIS Ecosystem Landscape Land Use Vegetation
2015/7/29
This research was implemented in Miyagi Prefecture, northeastern Japan. In recent years, the rich biodiversity of this prefecture has
been decreasing rapidly due to loss of forest and traditional co...
FORESTLAND CLASSIFICATION USING AN ECOSYSTEM APPROACH
Forestry Management Ecosystem Landscape DTM GIS
2015/7/29
This study focuses on using an ecosystem approach for forestland classification of the Liukuei Experimental Forest of Taiwan
Forestry Research Institute. The content includes the delineation of ecos...
Generalized additive models as an alternative approach to the modelling of the tree height-diameter relationship
nonparametric method Norway spruce Petterson function
2015/7/2
Generalized additive models were tested using three types of smoothing functions as an alternative for
modelling the height curve. The models were produced for 23 forest stands of Norway spruce (Pic...
Multivariate statistical approach to comparison of the nutrient status of Norway spruce (Picea abies [L.] Karst.) and top-soil properties in differently managed forest stands
humification nutrition cation exchange capacity (CEC)
2015/3/6
The soil is an irreplaceable component of forest ecosystems. Soil-forming processes directly influence element cycling (EC). Plant-soil interaction is a specific part of EC. Plant-soil interactions we...
Predicting Stem Windthrow Probability in a Northern Hardwood Forest Using a Wind Intensity Bio-Indicator Approach
Windthrow Prediction Species Wind-Firmness Tolerant Hardwood Forests Silviculture Guidelines
2013/3/4
Unlike fire or insect outbreaks, for which a suppression program can be implemented, it is impossible to prevent a windstorm event or stop it while it is occurring. Reducing stand susceptibility to wi...

Approach Using the Short-time Period Water-budget Method of Calculating Daily Evapotranspiration throughout a Water Year
critical discharge days of direct discharge discharge-duration curve daily evapotranspiration short-time period water-budget
2009/8/21
This study proposed the short-time period water-budget method, and estimated evapotranspiration in the Nutanotani watershed (34º27′N, 136º14′E), Mie University. The proposed method consisted...
Blue ecology：A cross-cultural approach to reconciling forest-related conflicts
blue ecology blue revolution conflict resolution fresh water First Nations Mt. Ida, waterbased
2009/2/11
Fresh water has a unifying role at the ecosystem and human level. Water, without fail, is recognized throughout the globe as crucial to human life. By examining a dispute resolution case study relatin...
An empirical approach to predicting water quality in small streams of southern British Columbia using biogeoclimatic ecosystem classifications
baseflow biogeoclimatic ecosystem classification British Columbia conductivity
2009/2/11
Water quality data from a synoptic survey of low-order streams (n = 581) were investigated as a function of the biogeoclimatic zone and moisture subzone groupings of the biogeoclimatic ecological clas...
