Adaptability analysis and risk assessment of Centaurea solstitialis in China
[Aim]Centaurea solstitialis L.is a very dangerous weed that is classified and controlled as a noxious weed in areas such as the United States and Australia.At present,the colonization of C.solstitialis has been found in Xinjiang which shows a tendency to spread.The purpose of this study is to provide theoretical basis for early warning and control by Adaptability analysis and risk as-sessment of C.solstitialis in China.[Method]MaxEnt model was used to predict the potential geographic distribution of C.solstitialis in China,and multi-index assignment was used to to conduct quantitative analysis for the risk of invasion.[Result]The potential habitat area of C.solstitialis in China reached 32.96%,of which the areas of high,medium and low habitat were 11.21×104 km2,34.16×104 km2 and 272.28×104 km2,respectively.The comprehensive risk assessment value of this weed was 2.01,belongs to high-ly dangerous.[Conclusion]C.solstitialis could occur at many areas of our country.The results provide the necessary theoretical ba-sis for establishing a long-term early warning and control mechanism of C.solstitialis.
