摘要：【目的】基于野外调查、植物标本采集与鉴定及前人研究记载,汇总并整理出磴口县维管植物名录,为该地区生物多样性保护提供理论依据。【方法】对磴口县维管植物种类组成、生活型、水分生态类型和植物区系地理成分进行统计分析。【结果】磴口县野生维管植物隶属于54科、164属251种,以菊科、藜科、豆科、禾本科和蓼科为优势科;植物的生活型以多年生草本为主,占总种数43.824%,其中乔木占2.00%、灌木占15.94%、半灌木占8.76%、一年生草本占27.89%、寄生植物占1.20%,藤本植物占0.40%;水分生态类型以旱生(包括超旱生、强旱生、旱生和中旱生)和中生(包括旱中生、中生、湿中生)为主,占总种数95.63%,湿生植物占4.00%,水生植物占0.40%;【结论】磴口县植物区系地理成分丰富多样,在亚洲中部荒漠区系为主体的背景下,受温带成分、东亚成分和古地中海区成分的影响。
【Objective】Based on field investigation,plant specimen collection and identification and previous research records,the list of vascular plants in Dengkou county was summarized and sorted out,which provided a theoretical basis for biodiversity conservation in this area.【Method】The species composition,life form,water ecological type and floristic geographical composition of vascular plants in Dengkou county were statistically analyzed.【Result】The wild vascular plants in Dengkou county belong to 54 families,164 genera and 251 species.Asteraceae,Chenopodiaceae,Fabaceae,Gramineae and Polygonaceae are the dominant families.The life forms of plants were mainly perennial herbs,accounting for 43.824%of the total species,of which arbors accounted for 2.00%,shrubs accounted for 15.94%,semi-shrubs accounted for 8.76%,annual herbs accounted for 27.89%,parasitic plants accounted for 1.20%,and vines accounted for 0.40%.The water ecological types of plants were mainly xerophytes(including super xerophytes,strong xerophytes,xerophytes and mesoxerophytes)and mesophytes(including xeromesophytes,mesophytes and hygromesophytes),accounting for 95.63% of the total species,hygrophytes accounted for 4.00%,and aquatic plants accounted for 0.40%.【Conclusion】The geographical composition of the flora in Dengkou county is rich and diverse.Under the background of the desert flora in central Asia,it is influenced by temperate elements,East Asian elements and ancient Mediterranean elements.
