摘要
对外来入侵杂草三裂叶豚草种群的空间分布研究结果表明,在开阔地、河堤、林地3种生境条件下均为聚集分布,但聚集强度不同,开阔地>河堤>林地;种群的聚集分布是三裂叶豚草生物学特性和生境条件共同作用的结果,其中种子传播方式和生境光照条件差异是影响其种群分布的重要因子。
Spatial distribution pattern of Ambrosia trifida L population was studied. The results showed Spatial distribution of Ambrosia trifida L populations were clumped distribution in open ground, riverbank and woodland, but there were differences in term of intensity and the order of increase was open ground, riverbank and woodland; the distribution pattern of Ambrosia trifida L population was influenced by the biological characters and inhabitation environment, and diffusion pattern of seed and ambient light illumination were important factors.
