汾河临汾段湿地植被区系多样性研究

Study on Floristic Analysis of Wetland Vegetation in Linfen Section,Fenhe River Watershed,Shanxi

本文在野外调查的基础上,根据植物区系分析得出:在各类植物区系地理成分中,北温带分布和世界分布属(各25属)具有明显优势,说明该地区湿地植物区系具有温带特征.北温带分布种(24种)在区系组成中占有显著优势,表明汾河临汾段湿地植物区系的温带特性.

Based on the data of field plots,there are 111 species of vascular plants in the wetland vegetation in Linfen Section,Fenhe River Watershed,Shanxi,which belong to 80 generas and 36 families.The hygrophyte,hydrophyte and mesophyte play an important role in the floristic elements.North temperate type and cosmopolitan（each 25 genera） are account for dominant position in the total genera.Moreover,North temperate species（24 species） dominate in the total species.It means that the wetland vegetation has obvious temperate characteristics.
