摘要:

随着水生植物的大量应用,水域环境的生态安全越来越受到关注。水生植物入侵具有一定的生物学、区系地理、生态位和生境特征,对水生植物的生态安全评价可在一定程度上防止水生植物引种的盲目性。该文针对来自水生外来入侵植物的生态安全威胁,分析了水生外来入侵植物的入侵特征及其危害,提出了水生植物引种的生态安全评价的内容、程序、指标体系和方法。

Abstract:

With the using of aquatic macrophytes,ecological security of water environment becomes a research focus. The invasion of aquatic plant has some biological characteristics,floristic geography,niche characteristics,and habitat characteristics. Ecological security assessment of aquatic plant can prevent from blindness in aquatic macrophytes introduction to some extend. Through the analyses of the characteristics and hazard of aquatic invasive alien plants that threaten the ecological security,this paper proposed the content,process,indicator system,and method for the ecological security assessment of aquatic macrophytes introduction.
