| 摘 要： | 探讨了草地生态安全及其评价的概念与内涵,认为草地生态系统安全判断与度量准则应该是草地生态系统健康、草地生态系统服务功能及生态风险与管理的科学统一。同时尝试提出了草地生态系统安全评价的"健康-服务功能-风险与管理(health-service-risk and management,HSRM)"模型,构建了HSRM评价模型的指标体系,提出草地生态安全评价中草地生态安全度计算公式和安全状态分级标准。

| Abstract: | On the basis of the development of ecosystem security and pastoral ecosystem security research,this paper analyzes the concepts and characteristics of pastoral ecosystem security.Pastoral ecosystem security was thought of as an integrated concept of ecosystem health,ecosystem services and ecosystem risk and management.A new pastoral ecosystem security assessment modeling was established about "health-service-risk and management(HSRM)",and the index system was analyzed on pastoral ecosystem security assessment.It provided a new calculation formula on the measure of pastoral ecosystem security,and advanced the criterion and levels for its identification. |
