【摘要】 在薇甘菊为害严重的深圳、东莞设置试验地,观测经除草(包括薇甘菊)后种植乔灌草等人为干预群落对薇甘菊的影响.研究表明:薇甘菊生物量与其它植物总盖度的关系极显著地符合负指数曲线模型;薇甘菊盖度、密度分别与其它植物总盖度呈极显著或显著负相关,并可很好地拟合线性模型;通过生态措施控制薇甘菊危害具有一定的可行性.更多还原

【Abstract】 Experimental sites were established in Shenzhen and Dongguan of Guangdong province where the Mikania micrantha caused great damage to the local plant communities After the weeds including all of Mikania micrantha were removed,the effect of planting in groups trees,shrub and herb on Mikania micrantha was observedResults shows that: Relationship between biomass of Mikania micrantha and total coverage of the other plants were very significantly fitted to negative exponential curve model;coverage,density of Mikania micrantha very significantly or significantly negatively correlated with total coverage of the other plants respectively,which were all fitted very well to linear models Controlling the Miknaia micrantha through the ecological measure has certain feasibility更多还原
