Population structure and interspecific association of Rhododendron huadingense, a rare and endemic species in China(珍稀特有植物华顶杜鹃的种群结构和种间联结)
华顶杜鹃(Rhododendron huadingense) 因分布地域的局限和资源量的稀少,被列为浙江省珍稀濒危植物。基于珍稀特有植物华顶杜鹃主要分布区的样地调查数据,通过分析群落相似性、种群结构,并基于2×2 联列表,应用共同出现百分率PC、联结系数AC、Pearson 积矩相关系数rp 和Spearman 秩相关系数rs等方法对华顶杜鹃乔木层22 个主要物种、灌木层24 个主要物种的种间联结的显著性和关联强度进行了定量测定,以揭示华顶杜鹃群落不同结构层次中主要物种的种间关系及其种群濒危的原因。结果显示:(1) 华顶杜鹃生长在光照较强的阳坡,不同产地所处群落物种组成差异较大。(2) 种群结...
