Studies on Biological Characteristics and Control Methods of Invasive Plant Macfadyena unguis-cati

Abstract

近年来,外来入侵植物猫爪藤[Macfadyenaunguis-cati(L.)A.Gentry]已对厦门鼓浪屿的生态环境、社会经济、旅游景观造成了不同程度的威胁,其危害如不及时遏止,将造成不可估量、甚至难以挽回的损失。本文通过室内外实验相结合的方法,对猫爪藤生物学特性和防除技术进行了研究,认为目前对鼓浪屿猫爪藤的防治原则是将其控制在危害水平以下,并提出了人工清除、化学清除与生态替代相结合的综合防治办法。主要实验结果如下: (1)对受猫爪藤危害最严重的地区鼓浪屿的初步统计表明,受猫爪藤危害的树种有41种。其中,受害最为严重的是台湾相思树(Acaciaconfusa),其次是榕树(Ficusmi...In recent years, invasive plant Macfadyena unguis-cati (L.) A.Gentry, has imposed a notorious damage to the Gulangyu Island located in Xiamen city, and the main damage levels include the direct threat to the biological ecosystem, the social economy, and the tourism landscapes. What is more, if the trend keeps going on without any prevention, the catastrophe could ruin the whole ecosystem, and it ...学位:工学硕士院系专业:海洋与环境学院环境科学研究中心_环境科学学号:20013402
