Abstract: Being centre on the ecosystem of lakes and reservoirs, based on the assessment of pressure of human activities, the ecological health of the lake and the service functions of the lake, a method system of comprehensive assessment of ecological security is proposed through rigorous theoretical derivation and model construction. Subsequently, the rationality and reliability of this method system are confirmed by the assessment of ecological security of Taihu Lake in China.

Key words: lakes and reservoirs, ecological security, comprehensive and quantitative assessment, Taihu Lake

摘要： 立足于湖库生态系统这一主体，以人类活动压力、湖库生态健康和湖库生态服务功能的评估为基础，通过理论推导与模型构建得出了湖库生态安全综合评估的方法体系。对我国太湖的生态安全状况进行了综合评估，从而佐证了该方法体系的合理性与可靠性。
