Agroforestry systems have been recognized as areas with high conservation potential, and there is a need to quickly assess
the biodiversity and tree stocking density available in these systems. However, it is not clear if the commonly used fixed
area plot is most efficient for sampling such landscapes, or if a different method could provide equivalent data with less
effort. Thus, a field and simulation-based study was carried out to compare the efficiency and accuracy of a variable area
transect versus the fixed area square plot. Field efficiency tests were carried out in three habitat types, robusta coffee
plantations, arabica coffee plantations and a privately owned forest fragment, in Kodagu, southern India. A simulation study
of bias, precision and accuracy of the two methods for tree density estimation also was carried out using various spatial
distribution patterns and densities. The variable area transect was significantly more efficient per unit effort in the field
than the fixed area square plot. In the simulation tests both methods performed equally well under random spatial distribution.
However, under simulated aggregated distribution both methods were positively biased (square plot up to 12% at low density,
variable area transect 9–12% at all densities), and under simulated regular distribution the variable area transect was slightly
negatively biased (−5 to −7% at medium to high density). The variable area transect thus can be recommended over the square
plot for rapid assessment of tree diversity and density, when the vegetation is expected to be randomly dispersed. 相似文献

To investigate the wood properties affecting the internal-check variation in boxed-heart square timber of sugi (Cryptomeria japonica), two cultivars, yabukuguri and kumotooshi were kiln-dried together by the high-temperature setting method and their internal checks were compared. There was a difference in the area of internal checks between the cultivars. Kumotooshi formed a larger area of internal checks, which was thought to be affected by the larger tangential shrinkage of kumotooshi. The number, total length, and total area of internal checks were significantly correlated with tangential shrinkage. The area of internal checks around the pith was also larger for kumotooshi, which might be affected by the larger tangential shrinkage in the core part of kumotooshi. The results supported that tangential shrinkage should be one of the important properties affecting the internal-check variation of sugi boxed-heart square timber. 相似文献

Boreal forests play an important role in global environment systems. Understanding boreal forest ecosystem structure and function requires accurate monitoring and estimating of forest canopy and biomass. We used partial least square regression (PLSR) models to relate forest parameters, i.e. canopy closure density and above ground tree biomass, to Landsat ETM+ data. The established models were optimized according to the variable importance for projection (VIP) criterion and the bootstrap method, and their performance was compared using several statistical indices. All variables selected by the VIP criterion passed the bootstrap test (p<0.05). The simplified models without insignificant variables (VIP <1) performed as well as the full model but with less computation time. The relative root mean square error (RMSE%) was 29% for canopy closure density, and 58% for above-ground tree biomass. We conclude that PLSR can be an effective method for estimating canopy closure density and above-ground biomass. 相似文献

To investigate the factors affecting the surface-check variation in boxed-heart square timber of sugi (Cryptomeria japonica), surface checks formed by the conventional kiln drying were compared for two stem heights of five cultivars with different wood properties. The total length and average length of the surface checks were greater at the upper part of the stems for all the cultivars. This might be caused by more sapwood at the upper part of the stem, and large drying stresses between the outer sapwood and the inner heartwood. The cultivars, in which tangential shrinkage was large owing to small microfibril angle, formed longer surface checks and smaller bow. There was a positive relationship between surface-check length and tangential shrinkage. The heartwood percentage and tangential shrinkage were thought to be important factors affecting the surface-check variation in sugi boxed-heart square timber. 相似文献

Summary The process of absorption and desorption of water by two-dimensional transport in wood was studied at a moisture content beyond the fiber saturation point. The transverse directions through a square wood beam were considered. A numerical model capable of describing the process was constructed and successfully tested. It can predict by calculation the kinetics of absorption when wood is immersed into water and the kinetics of desorption when it is exposed to air. The model gives a fuller insight into the process with the profiles of moisture content developed through the cross-section of the wood at any time.This work was carried out with the help and support of the French MRT and Wood Technical Center (CTBA) 相似文献
