Study on Vegetation Characteristics of the Water-level Fluctuation Zone in Hechuan District,Chongqing
The field survey of vegetation in the water-level fluctuation zone of Hechuan District was conducted using stratified sampling meth-od,the results showed that the water-level fluctuation zone in Hechuan District harbored 296 plant species,spanning 77 families and 205 gene-ra,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 iden-tified,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.
