本文采用层次分析法(AHP法)从景观的视角对长沙市湿地中应用较多的再力花、香菇草、蒲苇、粉绿狐尾藻和睡莲等5种外来植物的入侵性进行了综合评价。结果表明:根据综合得分将入侵性划分为Ⅰ~Ⅳ四个等级(得分由低到高),其中得分为Ⅱ级的有再力花和香菇草,得分为Ⅲ级的有蒲苇、睡莲和粉绿狐尾藻,5种植物的初步评价结果与实际表现比较一致;权重方面,群落生态>个体生态>群落景观,群落景观上5种植物得分相差不大且处于及格线上下,群落生态中的2个多样性指标权重较大且得分差距也较大,个体生态除睡莲外其他得分非常低,此现象不容忽视。

In this study,Analytic Hierarchy Process(AHP)was used to evaluate the invasion of 5 frequently occurred wetland plants of Thalia dealbata,Hydrocotyle vulgaris,Cortaderia selloana,Myriophyllum aquaticum and Nymphaea tetragona from the perspective of landscape.The evaluation results showed that the invasion of 5 plants was divided into 4 grades(Ⅰ~Ⅳ)from low to high according to their comprehensive scores.Hydrocotyle vulgaris and Thalia dealbata were classified into grade II,and Cortaderia selloana,Myriophyllum aquaticum and Nymphaea tetragona w...
