| 植物的区系组成特征研究能反映区域植被的组成、生态系统结构和生态状况。采用样方调查法，对四川渠县柏水湖国家湿地公园植物区系特征进行研究。结果表明，四川渠县柏水湖国家湿地公园内分布维管植物126科306属395种，其中蕨类植物19科23属31种，裸子植物4科6属6种，被子植物103科277属358种。分布的野生种子植物245个属划分为12个分布区类型、14个分布区变型，占15个中国种子植物属的分布区类型的80%，占31个属分布区亚型的45.16%，其中属于热带分布区类型及其变型的属数量最多，植物区系来源较为丰富，植物区系成分相对多样复杂。 |

| The study of plant flora composition is one of the important means to reflect vegetation structure, the structure and ecological status of regional ecosystems. This paper investigated the flora characteristics of Baishui Lake National Wetland Park in Quxian County, Sichuan Province by using sampling plot methods. The results showed that there were 395 vascular plant species, belonged to 306 genera and 126 families, including 31 fern species belonged to 23 genera and 19 families, 6 gymnosperms species belonged to 6 genera and 4 families, and 358 angiosperm species belonged to 277 genera and 103 families. The distributed 245 genera of wild seed plants were divided into 12 areal types and 14 areal variants, accounting for 80% of the areal types of 15 Chinese seed plant genera and 45.16% of the areal subtypes of 31 genera, mainly with tropical distribution and its variant. The results indicated the flora sources were relatively rich and the flora elements were relative complicated. |
