| 摘 要： | 对植物外来种的入侵及生态系统的影响进行综述与分析，植物入侵多种因子的影响，可分为外因和内因两类，植物外来种对生态系统的影响主要体现在生产力，土壤营养，水分，干扰体制，群落的结构和动态等方面，在管理外来种时，需对外来种的特性和影响因子进行系统的观察研究，采用机械法，化学方法和生物控制法等综合办法控制植物的入侵，引进植物引来种时，要对引进种的行为特性进行了调查研究，注意其安全性。

| Abstract: | The invasions of exotic plants and their effects of ecosystems were reviewed and analyzed.There are many factors which can effect plant invasions.Some of them can promote invasions of plants,while other factors can inhibit invasions.All factors can be divided into internal factors and external ones.The effects of exotic species to ecosystems are mainly on the productivity,soil,water,disturbance,community structure and dynamics.We should research the characters and effect factors of exotic plants,then integrated approach can be couducted to control the plant invasion.The exotic species behaviors and life cycle should be clarified before its introduction for safety. |
