Abstract:

The relationship between volume production and stand density, often termed the 'growth-density relationship', has been studied since the beginnings of forestry and yet no conclusive evidence about a general pattern has been established. Throughout the literature claims and counterclaims concerning the growth-density relationship can be found. Different conclusions have been attributed to the diverse range of definitions of volume and stand density among problems with study design and other pitfalls. Using data from two thinning studies representing non-intensively and intensively managed plant

Abstract:

Self-thinning quantifies the reduction in tree numbers due to density-dependent mortality. Maximum size-density relationships (MSDRs) are a component of self-thinning that describe the maximum tree density per unit area obtainable for a given average tree size, often quadratic mean diameter (D). An MSDR species boundary line has been defined as a static upper limit of maximum tree density -- D relationships that applies to all stands of a certain species within a particular geographical area. MSDR dynamic thinning lines have been defined as the maximum tree density obtainable within an individ

The experimental objective. The study was designed to establish the effects of crop stand density and fertilization on spring rape productivity. Statements to be defended: 1. Crop stand density and plant supply with nutrients affect the penetration of photosynthetically active radiation to the soil surface and various heights of crop canopy. 2. Under favourable nutritional conditions, spring rape reaches the maximum photosynthetic productivity at flowering in a crop with a lower stand density; while under less favourable conditions, the maximum photosynthetic productivity at flowering is achi

Abstract:

Forests have been proposed as a means of reducing atmospheric carbon dioxide levels due to their ability to store carbon as biomass. To quantify the amount of atmospheric carbon sequestered by forests, biomass and density estimates are often needed. This study develops, implements, and tests an individual tree-based algorithm for obtaining forest density and biomass using orthophotographs and small footprint LiDAR imagery. It was designed to work with a range of forests and image types without modification, which is accomplished by using generic properties of trees found in many types of im

Forest canopy structure is strongly influenced by stand density due to changing competitive interactions among the individual trees and in turn directly influences stemwood volume production. The structure and dynamics of forest canopies, particularly in relation to the production of stemwood, were examined in unmanaged, even-aged stands of two dissimilar tree species, Pinus contorta var. latifolia Engelm. and Abies lasiocarpa (Hook.)

Stand carrying capacity is the maximum size of population for a species under given environmental conditions. Site resources limit the maximum volume or biomass that can be sustained in forest stands. This study was aimed at estimating and determining the carrying capacity in loblolly pine. Maximum stand basal area (BA) that can be sustained over a long period of time can be regarded as a measure of carrying capacity. To quantify and project stand BA carrying capacity, one approach is to use the estimate from a fitted cumulative BA-age equation; another approach is to obtain BA estimates impli

O Ipê Felpudo (Zehyera tuberculosa (Vell) Bur) é uma espécie nativa, pioneira que possui um alto potencial silvicultural. Essa está ameaçada de extinção devido ao caráter extrativista e predatório da exploração florestal brasileira. A eliminação de complexos ecossistemas florestais por atividades agrícolas, agropecuárias, madeireiras e industriais tem levado a drásticas reduções da base genética dessa essência. O espaçamento é de grande importância para o desenvolvimento das árvores sob aspectos tecnológicos, silviculturais e econômicos. Esse influencia na morfologia e crescimento das árvores.

Given two samples from two populations, one could ask how similar the populations are, that is, how close their probability distributions are. For absolutely continuous distributions, one way to measure the proximity of such populations is to use a measure of distance (metric) between the probability density functions (which are unknown given that only samples are observed). In this work, we work with the integrated squared distance as metric. To measure the uncertainty of the squared integrated distance, we first model the uncertainty of each of the probability density functions using a nonpa

Large areas of the interior of B.C. are covered with densely stocked lodgepole pine {Pinus contorta) forests, 40-60 years old.

When stands have densities around 20,000 stems/ha or greater they are unlikely to produce merchantable trees within a reasonable period of time without treatment. To bring the more repressed stands back into timber production it is necessary to clear them and regenerate new ones with a more desirable stocking level (rehabilitation). A study of the

Abstract:

碩士<br>國立臺灣大學<br>森林環境暨資源學研究所<br>107<br>The purpose of this study is to understand whether forest environments of different densities can provide human psychological benefits, and which density forests have the best physiological and psychological benefits. Therefore, this study selected the permanent test plots of the Cryptomeria plantation from the No. 173 of the Xitou Tract Area of National Taiwan University Experimental Forest. We select three kinds of stand densities as the study area, high-density stand (10,000 N/ha), medium-density stand ( 1000 N/ha) and low-density stand (400 N/ha) and

Abstract:

Page xvi is missing from both the electronic and print copy<br>One-third of the North Island of New Zealand has been identified as requiring increased soil conservation if pastoral farming is to be sustainable. For over 50 years the planting of widely spaced poplar trees (Populus spp.) has been one of the main methods used to control soil erosion on hill pastures. Research has shown that these plantings have successfully decreased soil erosion but their impact on the productivity of pastoral farming has received little research attention. The research that has been undertaken has found poplars
