通过野外调查和协惯量分析法,对入侵植物粗毛牛膝菊（Galinsoga quadriradiata）在秦岭地区的生态适应性进行了研究.结果表明,该植物具有非常广泛的生态适应能力,在不同光照、不同水分、不同土壤肥力条件下都能很好地生长,具有很强的扩散能力,对于农作物、森林、本地植物和生物多样性的保护都具有潜在的威胁.结合牛膝菊生长迅速、花期较长、花序较多、种子产量巨大且具有较强的营养繁殖能力的生物学特点,牛膝菊的环境适应特性和生殖特性是其具有较强入侵性的原因.

The ecological adaptation of Galinsoga quadriradiata in Qinling Mountain was investigated by using co-inertia analysis based on field survey.Results show that this exotic invasive plant has a high level of ecological suitability.It can survive and develop in different conditions of illumination,soil moisture and soil organic.It can spread rapidly,which results in potential threat to crops,forestry,indigenous vegetation and biodiversity conservation.Its biological characters such as fast growing,long flowering season,producing more capitula,large seed output and vegetative reproduction further demonstrate that its ecological adaptation feature and reproductive traits make it more invasiveness.The results could be used to facilitate farther research and allow targeting control action against this plant.
