摘  要:
通过野外调查及资料统计,对凉水国家级自然保护区种子植物区系进行研究,以期了解该区种子植物区系的起源、组成、性质和特点。结果表明:凉水国家级自然保护区有种子植物71科240属454种,其中,裸子植物1科3属9种,被子植物70科237属445种。研究区按科的分布型统计,可分为6个类型,世界分布型含有34科(包括175属328种),热带分布类型共16科(包括20属30种),温带分布类型共21科(包括45属96种)。从科的地理成分看,该区植物区系以温带性质的分布型科为主体;该区属的地理成分可划分为10个类型,以温带分布类型占绝对优势,温带分布类型共计174属,占总属数的72.50%,为该区的种子植物区系的主要地理成分。
