安徽省马鞍山濮塘风景区植物群落多样性研究
0
()
摘要:
对濮塘风景区植物群落的10个乔木样地进行调查研究。据统计分析,在所调查样地中共存在维管植物143种(含变种),隶属于101属,62科。该区群落以山胡椒(Lindera glauca)、茅栗(Castanea seguinii)朴树(Celt-is sinensis)重要值最高,分别为36.82、31.09和24.13。各样地群落物种多样性指数较高,分布均匀,其Simpson指数、Shannon-Winner指数、均匀度指数R均值分别为15.07、3.16和0.82。对样地的植物生长型与物种多样性关系分析表明:群落内各层的物种丰富度的大小的顺序为灌木层>草本层>乔木层,群落总丰富度主要受灌木层丰富度的影响,Simpson指数和Shannon-Winner指数均为灌木层最大,乔木层和草本层的Simpson指数和Shannon-Winner指数变化不规则。

Abstract:
Plant community of Putang scenic resort was studied.In the 10 tree-quadrats,there are 143 species of vascular(including varieties),which belong to 101 genera and 62 families.Lindera glauca,Castanea seguinii,Celtis sinensis take up predominant positions,their importance value are 36.82,31.09,24.13,respectively,and plant community of Putang scenic resort has relatively high species indexes and relatively even distribution,their average Simpson indexes,Shannon-Winner indexes and Evenness are 15.07,3.16,0.82,re...
