摘要
据调查和统计,黄山现有野生种子植物129科、638属、1420种(包括亚种、变种和变型)。科、属、种的地理成分分析结果显示:科以泛热带成分为主(占48.5%),其中科的热带性地理成分占59.6%;属以北温带分布最多(占23.7%),其中属的温带性地理成分占61.7%;种以中国特有分布最多,而种的温带性地理成分占33.1%。该区的优势科(含6种以上)主要有椴树科、木通科、猕猴桃科、清风藤科、忍冬科等,它们大多为亚热带和温带分布科。结合优势科的分析,认为黄山种子植物区系具有温带和亚热带性质,并且温带区系性质明显。
According to investigation and statistics,there are 1420 species of wild seed plants (including subspecies,varieties and forms) which belong to 638 genera and 129 families in Huangshan Mt.Based on their geographical distribution,129 families are classified into 10 arealtypes,among them Pantropical element is dominant (485%),and the tropical elements make up 596%.638 genera are classified into 13 arealtypes,among them North temperate element is dominant (237%),and the temperate elements make up 617%.1420 species are classified into 14 arealtypes,among them endemic to China element is dominant (518%),and the temperate elements make up 331%.The dominant families (including more than 6 species) in this area are Tiliaceae,Lardizabalaceae,Actinidiaceae,Sabiaceae,Caprifoliaceae,etc.Most of them are subtropical and temperatedistributed families.According to the analysis of floristic elements and dominant families,this flora shows both temperate and subtropical in nature,and the temperate elements are superior.
