Structural Characteristics of Quercus Varibilis Natural Forest in Louguantai of Shaanxi
摘要
Abstract
Structural characteristics of Quercus variabilis natural forest was explored for proper management.Based on field surveys and analysis of the Quercus variabilis natural forest at Louguantai State-Owned Ecolog-ical Experimental Forest Farm in Shaanxi Province,this paper studied the species composition,horizontal and vertical structure,diameter class and stock volume of living trees,and natural regeneration of the stand.The results showed that:(1)the species composition of the stand was complex,8 associated tree species besides the dominant species Q.variabilis.(2)The understory vegetation was relatively diverse,with 9 shrub spe-cies and 10 herb species,and the layered structure was complete.(3)The living trees were predominantly in the small(Ⅰ)and medium(Ⅱ)diameter classes,accounting for 80.82％of the total.The stand stock was 242.17 m3/hm2.(4)The natural regeneration of the stand occurred through both seed and sprouting regen-eration,with seed regeneration being the primary.The seedling regeneration density was 2885 seedlings/hm2,indicating a poor regeneration grade.关键词
