Study of Distribution Pattern and Density of Vegetative Cover in Steppe and Forest Areas of Isfahan University of Technology
Since density is considered as one of the most important numerical indices to explain quantitative values of a plant community by affecting on many aspects and activity of ecosystem, on the other hand, awareness about plants distribution pattern in environment is an essential preparation for measurement and study of vegetative cover, therefore, in this research determination of density and dist...

متن کاملEstimation of Density using Plotless Density Estimator Criteria in Arasbaran Forest
Sampling methods have a theoretical basis and should be operational in different forests; therefore selecting an appropriate sampling method is effective for accurate estimation of forest characteristics. The purpose of this study was to estimate the stand density (number per hectare) in Arasbaran forest using a variety of the plotless density estimators of the nearest neighbors sampling me...

temporal distributions of RLD using experimental measurements and simulations. The root length density (RLD) is an important parameter to model Experimental measurement approaches of RLD diswater and nutrient movement in the vadose zone and to study soil– tributions include the root sampling method (Kumar root–shoot–atmosphere interactions. However, it is difficult and timeet al., 1993) and rhi...
متن کاملPhotographic method to measure the vertical distribution of leaf area density in forests
Many current vegetation–atmosphere models require structural information describing the canopy in order to calculate rates of mass and energy exchange. One of the most important pieces of information is the variation with height in leaf area density, ρ (m2 leaf area per m3 canopy volume), but it is notoriously difficult to measure this in forest canopies. Consequently, very few data on ρ exist ...
