摘要
分析危险性杂草多斑矢车菊在我国的适生性,预测其在国内的潜在分布区,评估其侵入风险,可为相关的预警、检疫工作提供依据.利用MaxEnt模型对多斑矢车菊在我国的潜在适生区进行预测,并采用多指标赋值法对其入侵我国的风险进行定量分析.结果显示,多斑矢车菊在我国的潜在适生区占比达26.13％,其高度、中度、低度适生区面积分别为1.48万、44.81万、204.61万km2.综合评估其危险性,入侵风险值R=2.16,处于高度危险水平,应提高警惕.
Abstract
The aim of this study is to establish a theoretical basis for the early warning and control of Centaurea australis Pancic ex A.Kern.by analyzing and predicting its potential geographic distribution and risk assessment in China.A MaxEnt model was used to predict the potential distribution of C.australis in China,and a multi-index assignment method was used to quantitatively analyze the risk of its invasion in China.The results showed that the potential habitat area of C.australis in China constituted 26.13％of the total area,with the high,moderate,and low suitable habitat areas accounting for 14,800 km2,448,100 km2,and 2,0461,000 km2,respectively.The comprehensive risk assessment score for this weed was 2.16,indicating that it is at a high risk level and therefore requires attention.
