| 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. |
