Investigation on invasive alien plants in Qingxiu Mountain Scenic Area of Nanning
摘要
Abstract
The spread of invasive alien plants has emerged as a global ecological challenge.A comprehensive under-standing of their distribution and characteristics serves as a fundamental basis for both the scientific utilization of plant re-sources and effective ecological risk prevention.The species composition,life forms,origins,modes of introduction,re-productive modes,and hazard status of invasive alien plants in Qingxiu Mountain Scenic Area of Nanning were analyzed in this study by field surveys using spline method combined with literature reviews.The results showed that there were 48 invasive alien plants in Qingxiu Mountain,belonging to 21 families and 37 genera.The Asteraceae plants had the most species,with 10 species.Among invasive plants in Qingxiu Mountain,herbaceous species were overwhelmingly domi-nant(39 species,81.25%of the total).Species originating from the Americas accounted for 42 species(87.5%of the to-tal).According to the Chinese Invasive Alien Species Information System's classification of invasion levels,there were 11 species categorized as highly invasive,11 as severely invasive,9 as locally invasive,9 as generally invasive,and 8 as pending observation.Based on the current survey results,the following control measures are proposed:(1)Establish a database of invasive alien plants and a risk assessment system in Qingxiu Mountain;(2)Pay particular caution with American-origin species during landscape plant applications and species introductions;(3)Enhance the management and monitoring of alien plants;(4)Implement timely eradication of invasive alien plants prior to their flowering and fruiting stages,or apply chemical control and replace control with local plants.关键词
