Effects of Stand Structure on Forest Growth:A Review
摘要
Abstract
Forest stand structure is a key factor that must be considered in forest management.It not only influences forest growth and yield,but also profoundly influences ecosystem stability,health,multifunctionality,and sustainability.However,the mechanisms by which stand structure affects forest growth are highly complex and have not yet been systematically summarized.This paper reviews studies on the relationship between stand structure and forest growth,by synthesizing and analyzing existing literature,to draw the following main conclusions:1)There are diverse ways to be employed for indicator selection and research methodologies.Current studies widely adopt seven categories of stand structural indicators,ranging from tree species composition to spatial patterns,and five categories of forest growth indicators spanning from individual trees to stand,reflecting a multiplicity of research perspectives.Methodologically,regression analysis and structural equation modeling are particularly widely applied.The latter demonstrates unique advantages in addressing the complex systemic issues due to its capacity to elucidate both direct and indirect causal relationships among multiple variables;and 2)The influence of stand structure on forest growth is not a simple linear relationship but exhibits positive(promotive),negative(suppressive),or neutral(insignificant)relationships,characterized by inherent uncertainty.Positive effects can be explained by theories such as niche complementary effect,selection effects,and plant-soil feedback mechanisms.In contrast,negative or neutral effects may be attributed to theories like asymmetric competition for light among plants or the absolute dominance of specific trees in stand development.By analyzing the relationship between stand structure and forest growth,this study aims to provide a reference for integrated research across multiple scales and factors and for precision forest management practices in the future.关键词
