摘要
原产于中国的杜鹃花由于具有观赏价值被没有杜鹃花天然分布的英国引种,在脱离人为控制后迅速大量繁殖,对当地造成巨大影响,形成外来种入侵。在阐述杜鹃花及英国引种情况的基础上,通过不同假想条件提出3种不同的杜鹃花在100万年后无人为影响下的生长模式假想:1)成为优势物种,改变群落进化方向;2)改变当地自然环境,最终走向灭绝;3)与当地种进化军备竞赛,协同进化达到新的生态平衡。
Rhododendron is native to China, and introduced to British for ornamental value. Rhododendron is treated as exotic invasion specie in British for enormous influence of rapid mass propagation on local environment. This paper reviews the introduction situation of Rhododendron in British, and carries out three growth pattern hypothesis of British Rhododendron in million years later without anthropogenic influence under different conditions. Firstly, Rhododendron becomes advantage species and modifies the community evolution. Second, Rhododendron modifies the local environment system, and finally makes for extinction. Third, competed to the local species, and finally forms the ecological balance with local species.
