摘    要:对薇甘菊(Mikania micrantha H.B.K)在不同生境下生长状况及其对其它植物的危害程度的研究表明,这种热带杂草是喜光、好湿的。薇甘菊伴生物种以藤本植物居多。其中葛藤和五爪金龙出现的频度最大。薇甘菊及其伴生种通过攀爬树冠,形成盖幕作用而对其它植物造成危害。在森林内薇甘菊危害的对象主要是低矮的乔木对高大乔木影响不大。

关 键 词:薇甘菊  杂草  危害  生境  生存  生态特性

Abstract:Mikania micrantha, a harmful exotic weed in southern China, likes to grow in humid soil under high light intensity. This climber commonly grows together with other vines such as Pueraria lobata and Ipomoea cairica. They climb to tree crown and cause damage by forming a cover on the canopy. Fifteen sites in Guangdong Province where M. micrantha is distributed were investigated from October 1998, and some plots were sampled in March 2000. The habitat and the growth of M. micrantha, soil moisture, light intensity, cmmunity characteristics, biomass as well as the damaging effect on other plants are described. In less closed forest (<6 m high), some trees and shrubs such as Lisea rotundifolia var. oblongifolia, Ficus hispida, Aporosa chinensis, etc. were damaged by M. micrantha, but less damage was observed in dwarf shrubs and herbs. In closed forest, M. micrantha can not grow well, which affects less the tall trees.
Keywords:Mikania micrantha  Exotic species  Invading weed  Damaging effect
