| 摘 要： | 通过对温州地区菊科入侵植物的分布特点、适宜生境、原产地、生活习性等几方面的分析，探讨温州地区外来植物入侵与扩散的一般特征与机制，为进一步开展入侵生物学与生态学研究提供基础资料。结果表明：菊科入侵植物绝大多数来自美洲，多为一、二年生植物；15种菊科植物除苏门白酒草、豚草、睫毛牛膝菊、大花金鸡菊分布较窄外都已广泛分布且多数适应各种生境，这表明外来菊科植物在温州已是一类十分普遍的杂草；温州适宜的气候及环境，再加上菊科植物所具有的繁殖和传播特性，使得它们能顺利入侵成功；种间关联分析表明，外来菊科植物之间既有相似的生物学特性，某些种间有着协同作用，又有各自特有的性质以保证对新生境的适应。

| Abstract: | In order to study the general characteristic and mechanism of alien plants＇ invasion and spread, the distributive characteristics, habitat, origin and habit of Compositae invasive plant were analyzed. The results showed： Most invasive plants of Compositae came from America, which were almost annual or biennial species; 15 species of Compositae distribute wide and befit in different forms of habitats, except for the 4 species： Conyza sumatrensis, Ambrosia artemisiifolia, Galinsoga ciliate, Coreopsis grandiflora, which proves that they are very widespread weeds in Wenzhou; The characteristics of reproduction and radiation which Compositae have, in addition to the fitting climate and environment of Wenzhou, made them invade big and successful; The analysis results of interspecies relationship about these invasive plants of Compositae show that similar biology characteristic make cooperating effect among certain species as well as have some specialities so that to accommodate themselves to adapt their new habitation. |
