摘要

根据乔木层次优势种、灌木层优势种和草本层优势种将分布在广西的黧蒴锥〔Castanopsis fissa Rehd.et Wils.〕林分为5个群丛,且各群丛的优势种均为黧蒴锥。对5个群丛的地理分布、生境特点、群落结构和物种组成也进行了分析。这5个群丛分别为:黧蒴锥-鼠刺-杜茎山-狗脊+金狗群丛(C.fissa-Itea chinensis-Maesa japonica-Woodwardia japonica+Cibotium barometz Assoc.)、黧蒴锥-鸭脚木-罗伞树+东方乌毛蕨群丛(C.fissa-Schefflera octophylla-Ardisia quinquegona+Blechnum orientale Assoc.)、黧蒴锥-鸭脚木-九节木+东方乌毛蕨群丛(C.fissa-Schefflera octophylla-Psychotria rubra+Blechnum orientale Assoc.)、黧蒴锥-基脉润楠-野锦香-金狗+东方乌毛蕨群丛(C.fissa-Machilus decursinervis-Blastus cochinchinensis-Cibotium barometz+Blechnum orientale Assoc.)和黧蒴锥-茶杆竹+淡竹叶群丛(C.fissa-Pseudosasa amabilis+Lophatherum gracile Assoc.)。 

Abstract

The Castanopsis fissa Rehd. et Wils. forests in Guangxi of China are classified into five associations according to sub-dominant species in trees layer, dominant species in shrub and herb layers, and in these associations,  C. fissa is the dominant species. Geographical distribution, habitat property, structure and species composition of five associations have been described. The seassociations are C. fissa-Iteachinensis-Maesajaponica-Wood wardiajaponica+Cibotium barometzAssoc.,  C. fissa-Schefflera octophylla-Ardisia  quinquegona+ Blechnum  orientale Assoc., C.fissa-Scheffleraoctophylla-Psychotria rubra+ Blechnum orientaleAssoc., C. fissa-Machilusdecursinervis-Blastuscochinchinensis-Cibotium barometz+Blechnum orientale Assoc.andC.fissa-Pseudo sasaamabilis+Lophatherum gracileAssoc.
