摘　　要：对黄顶菊(Flaveria bidentis Kuntze)在不同生境下入侵、生长状况及与其共存的伴生种的调查和研究表明:黄顶菊喜光、喜湿、耐盐碱.在水分多、光照充足的生境中生物量高;反之,生物量减少.其伴生种以草本植物居多,其中狗尾草、碱蓬、苘麻出现的频率较大.黄顶菊为1年生草本植物,生长迅速,可高达2 m以上,分枝多,其结实量大,可与其它植物竞争生境因子而造成很大威胁.由于其根系粗大,不易铲除,若幼苗期不加控制,将对其它植物造成危害.The alien invasion and the growth of Flaveria Bide.ntis Kuntze in different habitats were investigated and studied. The results show that it likes to grow in humid soll under high light intensity, which can bear the salt and alkaline. In the plentiful water and high light intensity habitats, it has high biomass, otherwise it has low biomass. It commonly grows together with herbs such as Setaria viridis Beauv. , Suaeda glauca Bge. , Kbution thcophrasti Medic. Flaveria Bidentis Kuntse is an annual herb, which grows rapidly. It is above two meter in height and has many branches and hearing fruit in large quantity, so it can compete with other plants for factors under different envionments and will he a quite threat to other plants. The department of its root is bulky, so it isn＇t easily uprooted. If it is not controled in seedling, it will cause serious harm to other plants.
