Flora analysis of riparian plant communities on the northern slope of Changbai Mountain

Abstract

Abstract: This study was conducted in the riparian forest of Erdaobaihe River, and the flora of riparian plant communities on the northern slope oi Changbai Mountain was researched and analyzed.There were 288 vascular plant species belonging to 169 genera and 68 families, among them, 26 plant species belonging to 16 genera and 11 families were fern, and 262 plant species belonging to 153 genera and 57 families were spermatophyte.Among spermato-phyte, there were 9 gyrnnosperm species belonging to 6 genera and 3 families and 253 angiosperrn species belonging to 147 genera and 54 families.Among angiosperrn, there were 212 dicotyledonous species belonging to 118 genera and 45 families and 41 monocotyledonous species belonging to 29 genera and 9 families.All the results showed that there were abundant plant species in the riparian plant communities on the northern slope of Changbai Mountain.Analyses on the distribution area types of spermatophyte in the riparian communities showed that the distribution area types of genera and families were both abundant.For genus level, there were 9 distribution area types and 7 sub-types, and for family level, there were 6 distribution area types and 2 sub-types.The riparian plant communities had a temperate characteristic, and there were 117 genera, which were accounted for 76.5% of all the genera of spermatophyte, belonging to all the different temperate distribution types.In addition, the flora of riparian communities had a complex component, and had close relations with Tropical and East Asia distribution type, but few relations with Mediterranean distribution type.The results also showed that riparian zone could play an important role in biodiversity protection.
