大熊猫野化培训圈森林植物群落多样性研究

本文应用植物群落学理论分析了卧龙大熊猫野化培训圈的植物种类组成、区系地理成分、优势树种以及生活型谱等特征。结果表明：大熊猫野化培训圈主要为野核桃、红肤杨、华西枫杨、连香树、扇叶槭、五裂槭、大翅色木槭、长序稠李、槐树等树种组成的落叶阔叶林。栖息地群落中分布的常见种子植物有71种，分属39科，58属，其中裸子植物3种，双子叶植物63种，单子叶植物5种；且以槭树科、杜鹃花科、忍冬科、蔷薇科、竹亚科、虎耳草科、菊科、百合科、禾本科等科植物构成优势组分。占组成植物总数的40．8％以上。从植物地理成分分析来看，无论是科分布型，还是属分布型，大熊猫栖息地植物都以温带分布类型为主，分别占57．5％和46．55％。植物群落生活型谱中以高位茅植物占优势，达56．34％，反映出大熊猫野化培训圈的植物群落具有温带落叶阔叶林特点，这与卧龙大熊猫栖息地的植物群落的生态特征相似。根据植物群落分类原则，将野化培训圈的植物群落共划分为连香树-拐棍竹-黑鳞耳蕨群落、野核桃-短锥玉山竹群落、野核桃-拐棍竹-艾蒿群落和野核桃-薄叶鼠李-小鳞苔草群落等4个类型。

A Study of the Diversity of the Plant Community in Giant Pandas' Field Training Area

In this paper,researches were made on the characters of floristic geographical composition,dominant species and biological spectrums of the plant community in the giant pandas' field training area in Wolong Nature Reserve according to the theory of plant community.The results showed that 39 families,58 genera and 71 species were found in the community,and the family and genera which belong to the type of the temperate distribution region were main.And phaenerophytes were dominant in the biological spectrums of the community,reflecting its features of temperate deciduous and coniferous forest.Four types of plant community in the field training area were divided on the basis of the principle of plant community classification,.
