贵州百里杜鹃大草原景区迷人杜鹃群落特征研究

为了解贵州百里杜鹃大草原景区迷人杜鹃群落特征,采用设置样地的方法,对迷人杜鹃物种组成、生活型、数量特征、物种多样性等群落学特征进行研究,结果表明,该群落由7科10属12种植物组成,寡属种的数量较多,并且除了杜鹃花科在属种数上略显优势外,其他科的组成都比较分散;群落生活型以高位芽植物占优势;迷人杜鹃在群落中起显著作用,控制整个群落的结构、组成和生境状况;整个植物群落多样性指数偏低,是一个简单、不稳定、抗干扰能力弱的群落。

Study on community characteristics of Rhododendron agastum in the prairie scenic area of Baili Rhododendron protection zone in Guizhou

In order to comprehend the community characteristics of Rhododendron agastum in the prairie scenic area of Baili Rhododendron protection zone in Guizhou,the community characteristics such as species composition,life form spectrum,quantitative characteristics and species diversity of R.agastum were researched based on the typical sample plots.The results were summaried as follows: the community of R.agastum was composed of 12 species belonging to 7 families and 10 genera,most genera contained only single species,and Ericaceae had an slightly advantage on genera number,however,the species composition of other families were more dispersed.The phanerophytes was dominant in the life form spectrum of this community.R.agastum in the community played a significant role,controlling the structure,composition,and the habitat situation of the entire community.The community showed a lower species diversity index,and it was simple,unstable,also poor in anti-jamming capability.
