摘　　要：采用分层取样法对合川区消落带植被进行实地调研,结果表明:合川区消落带植物有296种,涵盖了77科205属,以禾本科和菊科为主;草本植物占比82.77%,在调研植被中占主导地位;消落带人工干预相对较少,野生植物占比达85.81%,成为主要来源;外来入侵植物的风险相对较小,仍需要加强监测和关注;双穗雀稗、棒头草、野古草等被确定为优势种,在不同高程带均有相应代表性的植物群落。最后,结合调研数据和分析,提出了消落带植物配置建议。The field survey of vegetation in the water-level fluctuation zone of Hechuan District was conducted using stratified sampling method,the results showed that the water-level fluctuation zone in Hechuan District harbored 296 plant species,spanning 77 families and 205 genera,with Poaceae and Asteraceae being predominant;herbaceous plants constituted a substantial 82.77%,establishing their dominance in the surveyed vegetation.Human intervention in the water-level fluctuation zone was relatively limited,with wild plants accounting for an impressive 85.81%,emerging as the primary contributors to the vegetation.The overall risk of invasive alien species was relatively low,but continuous monitoring and attention were deemed necessary.Dominant species such as Setaria viridis,Echinochloa crusgalli and Eleusine indica were identified,displaying representative plant communities across different elevation zones.In conclusion,based on the research data and analysis,this study proposed recommendations for the vegetation configuration within the water-level fluctuation zone.
