湖北孝感老观湖国家湿地公园植物区系特征研究

摘要

采用样线调查和样地调查相结合的方法,对湖北孝感老观湖国家湿地公园进行植物区系特征研究.结果表明,湿地公园分布有维管束植物58科131属165种,其中蕨类植物2科3属3种,裸子植物1科2属2种,被子植物55科126属160种.种子植物的科、属分布较为丰富,植物区系成分相对多样复杂;物种区系特征与老观湖的形成息息相关.%This study investigated the vascular plant biodiversity of Laoguan Lake,a national wetland park of XiaoGan,Hubei province,by using line intercept methods and sampling plot methods.The resuits showed that there were 165 vascular plant species,belonged to 131 genera,58 families.Among them,3 fern species belonged to 3 genera,2 family,2 gymnosperms species belonged to 2 genera,1 family,and the other 160 angiosperm species belonged to 126 genera,55 family.The results indicated the angiosperm species were rich in genera and families,the flora elements were relative complicated,and the flora character was close related to the formation of Laoguan Lake.
