Fig. 1. Functional traits value of dominant woody species in the karst forest. The circle in the box plot indicates the abnormal value; the percentage of data in the figure is the coefficient of variation; 1-10 represent species in the ordinate; the species number 1, Machilus cavaleriei; 2, Itea yunnanensis; 3, Lithocarpus confinis; 4, Carpinus pubescens; 5, Platycarya strobilacea; 6, Zanthoxylum ovalifolium; 7, Rhamnus heterophylla; 8, Stachyurus obovatus; 9, Rosa cymosa; 10, Dalbergia hancei. A, leaf thickness (LT). B, leaf area (LA). C, specific leaf area (SLA). D, leaf dry-matter content (LDMC). E, leaf tissue density (LTD). F, twig dry-matter content of branchlets (TDMC). G , twig tissue density (TTD). H, specific root length (SRL). I, fine root tissue density (FRTD).
