摘要
在文献查阅和实地调查的基础上,结合前人在外来物种入侵风险评估方面的研究成果,针对外来植物入侵红树林生态系统特征,建立了外来植物入侵红树林生态系统风险评估指标体系。该指标体系由准则层5个部分、指标层17个指标构成,分别从外来植物引入阶段、适生阶段、扩散阶段、危害阶段和防治阶段进行评估。并对互花米草入侵广西山口红树林保护区进行示范评估,其评估风险分值为86,入侵风险等级为一级,极高风险,应禁止引进,实行检疫。构建的体系能够较客观地反映外来植物的风险等级水平。
Based on the literature review and field survey, combining previous research achievements on the alien species invasion risk assessment, according to the characteristics of alien plant invasion of mangrove ecological, we have structured risk assessment index system for alien plants invade mangrove ecosystem. This index system consists of 5 parts, 17 indicators, from introduction stage, optimal growth stage, diffusion phase, harm stage to evaluate prevention stage. And take for example the invasion of Spartina alterniflora in Guangxi mangrove wetland, its risk score is 85, high risk. Spartina olterniflor should be banned to introduce and carry out quarantine. This system can reflect the alien plant risk grade level objectively.
