Investigation of exotic plant species in Hulunbuir grassland area
摘要
Abstract
[Objective]The investigation was carried out in order to master the composition,life form,origin,and introduction pathways of exotic plant in Hulunbuir grassland,and to lay a theoretical foundation for the management and prevention of invasive plants in the region in the future.[Method]On the basis of field investigation,relevant lit-erature was consulted to conduct species statistics and correlation analysis on exotic plants in Hulunbuir grassland.[Result]There are a total of 50 species of exotic plants,belonging to 17 families and 43 genera.The top three species are 11 species of Asteraceae,accounting for 22％of the total species,9 species of Poaceae,accounting for 18％of the total species,and 5 species of Amaranthaceae,accounting for 10％of the total species;In terms of lifestyle,annual herbaceous plants have the most,with a total of 28 species,accounting for 56％of the total number of species.The species native to the Americas are the most numerous,with 17 species,accounting for 36％of the total number of spe-cies.Intentional and unintentional introductions account for 52％and 48％of the total number of species,respec-tively,in the introduction channels.[Conclusion]There are many species of exotic plants in Hulunbuir grassland,mainly in Asteraceae,Amaranthaceae,and Poaceae families.The life form is mainly composed of annual plants,with the most species native to the Americas.The distribution area type of the family is mainly tropical components,while at the genus level,it is mainly temperate components.关键词
