Harm and Prevention of Invasive Plants From the Yunnan Jiaozi Mountain National Nature Reserve
This paper aims to better manage the alien plants from outside the Jiaozi Mountain National Nature Re-serve in Yunnan and promote the construction of the Jiaozi Mountain Nature Reserve.Through systematic field in-vestigation and literature data analysis,the current situation of invasive alien plants in Jiaozi Mountain is revealed.The invasion levels of invasive plants are classified based on species composition,source analysis,and harmful-ness.Corresponding control suggestions are proposed.The results showed that a total of 42 species of invasive plants were recorded in Jiaozi Mountain,belonging to 15 families and 34 genera.Among them,Asteraceae ac-counted for the highest proportion,reaching 38.09％,followed by Fabaceae(11.90％)and Solanaceae(9.52％);from a geographical perspective,the most invasive plants originate from the Pudu River,with 23 species,account-ing for 54.76％of the total number of invasive plants.According to the assessment results of the invasion status,there are 22 species with serious invasion levels or higher,and there are also some species that have not yet formed obvious harm but have a high risk of invasion.The Pudu River and tourist attractions should be designated as key prevention areas.
