摘要
从外来植物的入侵性和生境的可入侵性两方面综述了外来植物豚草的入侵机理研究进展,分析了豚草在秦皇岛地区的现状,以中国环境管理干部学院新校区为例调查了人类活动干扰对豚草的影响。豚草的入侵性与其自身所具有的生理生态学特性密切相关,生境的可入侵性则与其群落特征和受干扰程度等因素有关。目前豚草是秦皇岛地区自然群落的建群种,没有表现出入侵性。新校区调查结果表明:豚草在自然群落中零星分布,但受到人类活动干扰的生境中豚草表现出一定的优势度。因此,在豚草防治中应防止人类活动的过度干扰影响,以保护当地的生态环境。
A research review was presented on invasive mechanism of alien plant Ambrosia artemisiifolia in terms of its invasiveness and the habitat invisibility. The present situation of the plant was analyzed in Qinhuangdao region, and the new campus was taken as an example to investigate the effects of human activity disturbance on A. artemisiifolia. The invasiveness of A.artemisiifolia was closely related to its ecophysiological characteristics, while the habitat invisibility was impacted by community characteristics and disturbance degree. In present, the plant was a community construction species in this region, and showed no invasion. The investigated results showed that A. artemisiifolia distributed sporadically in the natural community. However, in the habitat disturbed by human activities, the plant had relatively high advantage. Therefore, excessive human activity disturbance should be prevented to control the invasive plant, by which to protect the local ecological environment.
