南五台栓皮栎林结构及分类的初步研究

A Study on the Structure Charcteristics and Community Classification of the Form. Quercus-variablis in Nanwutai

南五台栓皮栎林是秦岭北坡典型垂直地带性植被基带,也是关中盆地水平地带性植被——落叶阔叶林的组成部分。该地区栓皮栎林是由栓皮标为优势种的纯林,群落结构简单,垂直结构上各层界限明显,可分为乔木层,灌木层和草本层三层;层间植物不发达,林冠整齐,根据该地区栓皮栎群系的组成成分,可划分为栓皮栎-格氏撞羽-披针苔,栓皮栎-杭子梢-披针苔,栓皮栎-胡颓子-披针苔,栓皮栎-格氏撞羽+杭子梢-披针苔等四个群丛。整个群系主要由山毛榉科、豆科、檀香科、胡颓子科、莎草科和菊科等植物组成。栓皮栎林经济价值高,开发利用时应重视生态效益,但目前要以保护为主,故应迅速建立南五台自然保护区。

Nanwutai is loeated at the north slope of Qingling Mountains. The structure of the Form. Quereus variablis there is simple, fhe Form can be obviously devided into three layers at the vertical strueture; the aborous layer the shurb layer and the herbaceous layer. There are mainly the plants of Fagaeeae, Febaeeae, Santalaeeae, Cyperaeeae and Asteraeeae etc. In the form, according to the classification method in the Chinese Vegetation, the form can be derided into four associations.
