基于土地利用分析的区域生态风险评价——以北京市为例

Urban Ecological Risk Assessment Based on Land Utilization Analysis——Case Study of Beijing

摘要: 以北京市为例,基于土地利用分析,采用了国内外较为认可的生态风险评价方法,从风险受体、风险源、暴露及生态易损性等几方面内容综合分析得出了城市生态风险值的大小,并做出相应的等级划分.在给出必要的不确定性分析的基础上,结合区域自身特点,提出了具体的生态风险管理对策.

Abstract: As a case study of Beijing,based on the land utilization assessment,an identified ecological risk assessment method was used to estimate the risk values of urban ecological situation by analyzing risk receptors,risk sources,exposure,and ecological vulnerability,and a classification of risk was made.Some specific measures of ecological risk management were presented based on the regional characteristics of Beijing.
