Risk Assessment and Control Strategies of Invasive Plants in Natural Ecosystem of Northwest Yunnan
In order to explore the current situation and regional risks of invasive plants in northwest Yun-nan,and improve the level and ability of regional control against invasive plants,the data of spatial distri-bution,degree of harm,species flora and investigation frequency of 62 invasive plants collected from the cen-sus in Weixi County,northwest Yunnan was sorted and analyzed.A risk assessment model and method for in-vasive plants were proposed,and invasive risk assessments were conducted on the recorded invasive plants separately.The results showed that there were 52 invasive plant species among 62 species of exotic plants,in-cluding 13 species at risk level of secondary invasion,accounting for 25%,and 39 species with low risk level of tertiary invasion,accounting for 75%;there was no high risk plants of primary invasion.According to the invasion risk assessment level of each species,the classification control method was proposed to assess and control the risk of invasive plants,and measures for managing the risk of invasive species were discussed.
