摘要
通过定性和定量调查相结合的方法,对河南原阳省级湿地公园进行系统调查并分析。结果表明河南原阳省级湿地公园有植物种类66科222属407种,其中蕨类植物3科4属7种;裸子植物1科1属1种;被子植物62科217属399种;生活型分析表明,乔木16种,灌木4种,藤本植物1种,草本植物386种,可以看出河南原阳省级湿地公园维管植物以草本为主,占比超过94%,其次是乔木3.93%,藤本和灌木种类稀少;植物区系分析表明,科级层次上河南原阳省级湿地公园植物群落表现出亚热带气候带的分布区类型,在属级层面上表现出典型的温带植物区系组成。综合分析表明,河南原阳省级湿地公园植物物种组成与区系特征反映出湿地内黄河所涉及的地形、气候、人为干扰及河流自然干扰的综合特征。
Based on qualitative and quantitative investigations along riparian zone of Yuanyang Provincial Wetland Park, Xinxiang, Henan Province, the flora characteristics were investigated. The results showed that a total of 407 vascular plants belonging to 222 genera and 66 families were identified, among which pteridophyte had 3 families, 4 genera and 7 species;gymnosperm had 1 family, 1 genus and 1 species;and angiosperm had 62 families, 217 genera and 399 species. There were 16 species of tree, 4 species of shrub, 1 species of vine, and 386 species of herb. The floristic analysis showed the geographical element was complex. For family, cosmopolitan, tropic to temperate types were 46.88%, 34.37% and 18.75% of the total families, respectively. For genus, there were 105 genera belonging to temperature type, 61 genera belonging to tropic type, which showed the transitional characteristics of riparian plant. The result indicated that the species composition and flora in Yuanyang Provincial Wetland Park, Xinxiang, Henan Province were influenced by to-pography, climate, human disturbance and natural change of river.
