摘要
在四川盆地城市生态系统中,选择最典型的道路、荒地、农田、湖泊、河流5个生态系统对外来植物进行调查,分析外来入侵植物组成和分布特征。结果表明:四川盆地城市典型生态系统外来植物入侵形势严峻,河流和荒地生态系统外来植物入侵率高达100%;5个典型生态系统中有外来入侵植物共20种分布于11科18属;喜旱莲子草和小蓬草是分布最广的恶性入侵物种,并且已经逸为野生。外来入侵植物对四川盆地城市生态系统物种分布产生极大影响,但人为干扰能够显著影响外来入侵物种的分布。最后提出四川盆地城市生态系统外来入侵植物防治措施。
The quadrat survey method was used to analyze the vegetation community and distribution characteristic of invasive plants in the urban ecosystem of Sichuan Basin.The road,wasteland,farmland,lake and river ecosystem were selected as the typical ecological systems.Results showed that the alien plants invaded the city ecosystem of Sichuan Basin seriously with an invaded ratio 100%encroached river and wasteland ecosystems.There were 20 species alien plants which distributed in 11 families and 18 genera for the five typical ecosystems.Alternanthera philoxeroides and Erigeron Canadensis were the most widely serious invasive species,and the two invasive plants had been escaped and became the wild plant.The invade exotic plant impact seriously on the plant distribution in urban ecosystem of Sichuan Basin.However,the artificial disturbance could affect distribution of the invasive plants.The control strategies of the invasive plants in the urban ecosystem were also proposed.
