| 摘 要： | 随着经济的快速发展,外来植物,特别是外来入侵植物数量和分布范围不断增加和扩展,可能对北京现有的生态系统的稳定性与可持续发展产生较大影响。针对外来植物,特别是入侵植物的数量与分布问题,依据3年的北京各区县野外调查数据以及相关文献资料,分析了实地调查中所记录的北京地区72科165属234种外来植物的组成特点,包括原产地、区系特点和引入原因,并重点对入侵植物的组成与分布状况进行探讨。结果表明:北京市67.77%的外来植物原产于亚洲,38.03%属于世界分布植物。其中,从引进用途上,观赏植物所占的比例为28.22%;在物种组成上,菊科、豆科、蔷薇科种数最多。在野外调查记录的28种主要入侵植物分布上,通州分布的入侵植物最多,为18种,海淀区种类最少,只有1种。在上述研究的基础上,对北京市外来植物引种、外来入侵植物防治以及城市生物多样性保护等提出了对策。

| Abstract: | With the economic development, the number of alien species, especially invasive alien species, is increasing quickly, which might affect the stability and sustainable development of local society, economy and natural ecosystem. According to extensive field investigations in Beijing and literature consultation, 234 alien species which belong to 165 genera and 72 families were recorded including original distribution area, flora, the usage of plants and invasive alien species in Beijing. The results show that... |
