Spatial Heterogeneity of Specific Leaf Area and Leaf Construction Cost of Quercus liaotungensis Canopy

doi:10.13466/j.cnki.lyzygl.2015.04.025

Abstract

Abstract: Plant functional trait has been a hot topic of ecological research in recent years.Specific leaf area and leaf construction cost are important index factors in the research on harvest and expenditure of resources.The vertical and horizontal differences in the energy transmission and micrometeorological characteristics of forest canopy can lead to a considerable heterogeneity of functional traits.With Quercus liaotungensis,we studied the functional traits and their influence factors of different canopy positions.The results showed that CC on the top is higher than that at the bottom,but it is the other way around to SLA.Except the top and eastward parts,SLA in different canopy positions had significant differences;heat of combustion was the main influence factor for CC and SLA.

Key words: Quercus liaotungensis, forest canopy, specific leaf area, leaf construction cost, spatial heterogeneity
