| Abstract: | Canopy parameters and understory light regimes of three artificial forest stands in South China,i.e.,Eucalyptus,slash pine and mixed forest stands,were estimated using hemispherical photography based on quadrat method together with plant census,and the relationship between canopy structure and understory light regimes was analyzed.Leaf area indexes(LAI)of the 3 artificial forest stands were 1.9,2.7,and 2.6,respectively,and their CV(coefficient of variation)was 11.3%,14.4%,and 19.3%,respectively.Canopy Openn... |
