摘要
安徽琅琊山种子植物区系组成丰富,有种子植物132 科、522 属、925 种,其中裸子植物8 科、21 属、39种,被子植物124科、501属、886种。分析表明,琅琊山种子植物地理成分复杂,过渡性明显。区内132 科的地理成分可划分为15种分布型,522 属的地理成分可划分为15 种分布型、14 个变型,区系表现为温带性质。聚类分析结果显示,该区植物区系与安徽清凉峰、马鬃岭、福建龙栖山、浙江古田山关系密切,与安徽皇藏峪和山东沂山有一定差异。
There are 925 species of seed plants belonging to 132 families and 522 genera in Langya Mountain.Among them,there are 39 species of gymnosperm belonging to 8 families and 21 genera,886 species of angiosperm belonging to 124 families and 501 genera.Based on the analysis of geographical compositions of seed plants flora in Langya Mountain,it is indicated that geographical compositions of seed plants flora are comparatively complex and the transition feature is evident.132 families can be divided into 15 areal types,522 genera into 15 areal types and 14 areal subtypes in Langya Mountain.This flora has the characteristics of the temperate zone.According to the cluster analysis,the conclusion is acquired that the flora has a close relationship with those of Qingliangfeng,Mazongling,Longqishan and Gutianshan in seven relevant mountains.
