| 摘 要： | 大尺度区域高强度开发改变原有区域的生态系统与景观结构,引发的区域生态风险是难以避免的。如何从宏观上评价区域生态风险,其评价方法在不断实践发展,这成为当前环评研究的热点之一。在海南某一开发区的区域环评实践时,根据区域的特征,划分区域景观类型,提出景观结构的评价指标,建立评价模型,运用基于区域景观结构的生态风险评价方法,对开发区的生态风险进行动态的时空化分析、预测与评价。案例研究旨于提升区域生态风险评价方法的运用水平,丰富评价方式,完善技术手段,为区域生态风险评价实践服务。 |

| Abstract: | The regional ecological risk triggered by changes of the regional ecosystem and landscape structures of large-scale region developmented with high-intensity is not unexpected.Assessment methods of regional ecological risk is in continuous exploration,practice and improvement,and how do assess the regional ecological risk by macro level which become one of the hot spots of the current EIA's study.Making a REIA of one development zone in Hainan,the types of regional landscapes are diviced,the landscape evalua... |
