摘要: 对外来植物梭鱼草(Pontederia cordata L.)和蒲苇(Cortaderia selloana)形态特征、生长习性和繁殖特点进行了详细观察和系统描述,分析了梭鱼草和蒲苇的气候适生性,结合国内的气候类型,推测出梭鱼草和蒲苇可能的引种区域,并利用层次分析法(AHP)构建了两者的风险评估体系。结果表明,梭鱼草和蒲苇的入侵风险主要表现在环境适应能力强、具有扩散的可能性、防除的成本和难度比较高3个方面,有中度入侵风险,需要严格限制其引入,并加强监管。最后,针对梭鱼草和蒲苇的入侵风险提出了相应的对策和管理建议,并对下一步研究工作提出了一些设想。

Abstract: The growth habits, morphological and reproductive characteristics of the alien plants Pontederia cordata L. and Cortaderia selloana were detailed observed and systematically described. The climate suitability of P. cordata L. and C. selloana were analyzed, combining the domestic climate types, speculated possible introduction areas of P. cordata L. and C. selloana, and constructed the risk assessment system by using analysis hierarchy process(AHP). The results showed that the invasion risk of P. cordata L. and C. selloana was mainly manifested in three aspects, strong environmental adaptability, possibility of diffusion, high cost and difficulty of prevention. The two plants have a moderate risk of invasion, so their introduction needs to be strictly restricted and supervision strengthened. Finally, the corresponding countermeasures and management suggestions were proposed for the risk of invasion of P. cordata L. and C. selloana, and put forward some ideas for the next research work.

Key words: Pontederia cordata L., Cortaderia selloana, alien plant, invasion risk
