摘    要:采用植物群落学研究方法,对典型喀斯特区大方福建柏自然保护区内领春木(Euptelea pleiospermum)群落进行了研究。结果表明:群落植物种类丰富,科属组成极为分散,区系成分复杂。科级地理成分热带性质较强(45.28%),属级地理成分以温带性质为主(39.44%)。群落外貌以中、小型叶面积、单叶、落叶草质、革质、非全缘的高位芽植物组成为特征。垂直结构复杂,成层现象明显,可分为乔木层、灌木层、草本层和地被层,并有一定层间植物伴生。乔木层、灌木层、草本层的Shannon-Wiener指数分别为2.5561、2.6954、1.9145。

关 键 词:领春木群落  植物区系  喀斯特  贵州

Abstract:Based on the phytocoenological method,the Euptelea pleiospermum community of Dafang Fokienia hodginsis National Reserve in Karst area in Guizhou Province was researched.The results are showed as follows:There are various plants in the community of Euptelea pleiospermum.Its family and genus are scattered composition.The geographical element is complicated,with a relatively higher connection to the tropical element on family level by 45.28% and a relatively higher connection to the temperate element on genus level by 39.44%.It was characterized by phanerophyte with mesophylls and microphylls,simple,herbaceous,coriaceous,unentire leaves.The vertical structure of community can be divided into tree layer,shrub layer and herb layer as well as a definite number of interstratum plants.The Shannon-Wiener indexes of tree layer,shrub layer and herb layer are 2.5561,2.6954 and 1.9145,respectively.
Keywords:Euptelea pleiospermum community  Flora  Karst  Guizhou
