昆明市外来入侵物种现状及防控对策OACSTPCD

Kunming has been plagued by invasive alien species in recent years.By collecting and sorting out the published works and documents,the situation of invasive alien species in Kunming was statistically analyzed.The results showed that a total of 189 species of invasive alien species were recorded,including 111 alien plant species,dominated by families of Asteraceae,Fabaceae and Poaceae.The proportions of the top 5 families in the number of invasive alien plant species of Kunming and other regions in China were compared.It can be found that Kunming City and Yunnan Province had significant differences,but there were no significant differences with Henan,Anhui,Jilin provinces and Haikou.Invasive animal species are dominated by insects,accounting for 59.74%of total invasive animal species.The invasive alien species in Kunming mainly come from the Americas,accounting for 52%of all invasive species.Basing on the serious conditions of invasive alien species in Kunming,conscious monitoring is necessary,and a joint prevention and control administration department should be raised.
