山西文峪河国家湿地公园种子植物区系和植物群落分类排序

摘要

采用线路调查法和样方调查法,对山西文峪河国家湿地公园进行植物调查,对湿地公园内的植物进行区系分析,对植物群落TWINSPAN分类,对样方和物种进行DCA排序.结果 表明,湿地公园范围内共有植物68科206属337种,其中,蕨类植物5科5属7种,裸子植物1科3属4种,被子植物62科198属326种;共有湿地植物42科85属109种,其中,蕨类植物1科1属3种,被子植物41科103属135种;该区域的种子植物区系在科级和属级水平均体现温带特征;山西文峪河国家湿地公园植被可分为9个群落类型,其中6个是由湿地草本植物所组成的湿地群落;DCA排序图第1轴反映的环境因子是土壤含水量,第2轴所反映的生态因子还不明确.%The line survey method and the quadrat survey method are applied to investigate the flora of Wenyuhe National Wetland Park in Shanxi. The flora of seed plants in the wetland park was analyzed. TWINSPAN classification of plant communities and DCA ordination of quadrats and species were carried out. The results showed that this area contained 68 families, 206 genera and 337 species of seed plants, including 5 families, 5 genera, 7 species of Pteridophyta, 1 families, 3 genera, 4 species of gymnosperm, and 62 families, 198 genera and 326 species in Angiosperms. This area contained 42 families, 85 genera and 109 species of wetland plants, including 1 families, 1 genera, 3 species of Pteridophyta, and 41 families, 103 genera, 135 species in Angiosperms. About the flora distribution, no matter the level of families and genera, it reflected the typical temperate nature. The flora of Shanxi Wenyuhe National Wetland Park could be divided into 9 communities by TWINSPAN, of which 6 were wetland communities composed of wetland herbaceous plants. The first axis of the DCA rankingmap was soil water content, and the ecological factor reflected by the second axis was not clear.
