摘要
草地生态系风险评价是评价指标体系构建的核心内容之一。通过对草地生态系统中风险受体、风险源、暴露和危害的分析,从系统的危险性和脆弱性两方面构建了草地生态风险评价指标体系为生态危险性和生态脆弱性;为科学反映草地生态风险变化特征,进一步科学合理进行草地生态风险评价奠定基础,也为提高草地生态系统抵御风险的能力,实现草地利用与生态、社会、经济可持续发展提供决策依据。
Index system construction is the core of ecological risk assessment. In the paper,the ecological risk assessment system of grassland was built based on the analysis of risk receptor,risk source analysis,expo- stare and harm of ecological risk. It would be reflect the characteristics of grassland ecological risk and provide the decision of ecological risk assessment for the sustainable development of grassland use in regional ecology, society and economy.
