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。
Based on field investigation and statistical data, the paper reported 454 species of seed plant which belong ~o 71 families, 240 genera in Liangshui nature reserve area. There were 1 family, 3 genera, 9 species of gymnosperas and 70 families,237 genera, 445 species of angiosperm. According to the family distribution types, 6 distribution types were divided. There were cosmopolitan type 34 families, 175 genera and 328 species, tropical type including 16 families, 20 genera and 30 species,and temperate type including 21 families, 45 genera and 96 species. distribution types, 10 distribution types were divided. The temperate elements held absolute genera of temperate elements accounting for 72. 50% of the tatal genus,and also were the main seed plant plora in Liangshui nature reserve area. Aecording to the genera predominance with 174 geographical elements of
