| 摘 要： | 生态系统的脆弱性是一个含义广泛的概念，是生态系统内固有的特性，脆弱性只能在干扰的状态下才显现出来．而干扰（包括自然干扰和人为干扰）又是引起退化生态系统的原因，种类的入侵和消亡、种类组成的变化、生态系统的多样性和稳定性、生产力、生态位的分化及生态系统小环境变化则是研究退化生态系统形成和恢复的重要内容，本文探讨脆弱性与退化生态系统诸方面的关系以及在植被恢复上的应用．

| Abstract: | The fragility of ecosystem is a wide-confining term and is regarded as inherent property of an ecosystem. It could display only when exposed to disturbance which causes the degradation of ecosystem however it is impacted by natural or nonnatural factors. The concepts of fragility and stability, the fragility in relation to species invasion and extriction, to diversity and stability of ecosystem, to primary productivity, to niche differentiation as well as to microclimatic change of ecosystem are discussed. The application of theory of fragility to the vegetation recovery is suggested. |
