摘要:
金沙江干热河谷元谋段残存的锥连栎群落中植物种类组成较为简单,共发现68种植物,隶属于35科60属,其中,禾本科、蝶形花科、菊科、唇形科等科植物占有较大优势;从植物生活型和功能型来看,群落内以草本植物和多年生植物数量居多,分别占所有植物种类的58.8%和63.2%。不同类型群落中,除了扭黄茅始终为各群落中最为重要的优势种之外,同一草本植物在不同群落中的作用和地位存在较大差异;群落物种多样性及相似性程度较为低下,其ShannonWeiner指数在1.7~2.6之间,且与群落受干扰程度存在较大关联。
Abstract:
Species composition and diversity characteristics of different Quercus franchetii communities in dryhot valley of Jinsha River were studied based on the plots data. The results showed that there was a simple plant species composition in remained Q.franchetii communities in Jinsha River dryhot valley of YuanMou section. In communities,68 plant species were found,which belong to 35 families 60 genera,and Poaceae,Papilionaceae,Asteraceae,and Lamiaceae plants had a large advantage; in the plant life form and functional type,the majority of the plants within communities were herbs and perennials,which occupied respectively 58.8% and 63.2%. In Q.franchetii communities,excepted that Heteropogon contortus was eventually the most important dominant species,the same herb in different communities were quite different in the role and status. Simultaneously,Q.franchetii communities had lower species diversity and similarity,and ShannonWeiner index was between 1.7 and 2.6,which was correlated with the degree of disturbance of communities.
