Leaf Functional Traits of Larix gmelinii in Different Forest Types and Their Relationships with Soil Physicochemi-cal Factors
摘要
Abstract
Four types of Larix gmelinii forests in the northern Greater Khingan Mountains,namely herb-L.gmelinii forest(CLL),Rhododendron dauricum-L.gmelinii forest(DJL),Cladonia-L.gmelinii forest(SRL)and Rhododendron tomen-tosum-L.gmelinii forest(DXL),were selected as the research objects.Leaf functional traits of L.gmelinii and soil physi-cochemical properties were measured.One-way analysis of variance(ANOVA)and redundancy analysis(RDA)were adopted to explore the relationships between leaf functional traits and soil physicochemical properties.This study aims to provide a reference for scientifically evaluating leaf functional traits and environmental adaptation strategies of L.gmelinii,as well as relevant researches on the linkage between leaf functional traits and soil properties.The results showed that leaf functional traits differed significantly among the four forest types.The specific leaf area(SLA,ASL)was the highest in R.tomentosum-L.gmelinii forest,with a value of 161.45 cm2·g-1,while Cladonia-L.gmelinii forest had the maximum leaf dry matter content(LDMC,w(LDM)478.36 g·kg-1).Specific leaf area was significantly negatively correlated with leaf tissue density(DLT).The dominant soil factors affecting leaf functional traits varied across forest types.Leaf traits in herb-L.gmelinii forest were mainly governed by available phosphorus content(AP).Soil water content(SWC)and total nitro-gen content(w(TN))jointly regulated leaf traits in R.dauricum-L.gmelinii forest.Leaf functional traits of Cladonia-L.gmelinii forest were closely related to soil electrical conductivity(EC),and soil pH exerted a significant effect on R.to-mentosum-L.gmelinii forest.L.gmelinii adapts to the ecological environment by adjusting leaf morphology and nutrient contents during growth,and its leaf functional traits are closely associated with soil physicochemical factors.关键词
