摘要
在搜集整理2015年郑州市暴雨洪涝资料的基础上,从生态学的角度,运用能值分析方法评估区域洪涝灾害脆弱性。进而使用能值作为统一的度量尺度,以能值评价的结果和表征区域洪涝灾害脆弱性的能值指标为基础,借助地理信息系统(GIS)对郑州市洪涝灾害的脆弱性进行空间差异分析。结果表明郑州市洪涝灾害脆弱性的空间分布差异明显,大致呈现从中部向四周递减的趋势。新密市的脆弱性最高,其次是市区,脆弱性最低的是新郑市。结论表明,在暴露度相同的条件下,有效提高系统的适应能力是降低脆弱性的关键。
On the basis of the rainstorm and flood data of Zhengzhou in 2015,we applied the emergy analysis method to evaluate the regional vulnerability to flood disasters from the ecological perspective.The emergy was then considered as a normalized basis.Based on the results of emergy evaluation and the emergy index representing the regional vulnerability to flood disasters,we used the geographic information system(GIS)to analyze the spatial difference of vulnerability to flood disasters in Zhengzhou.Results showed that there were obvious differences in the spatial distribution of vulnerability to flood disasters.The vulnerability of Xinmi was the highest and that of Xinzheng was the lowest.In a whole,the vulnerability to flood disasters in Zhengzhou City tended to decrease from the middle to the periphery.Improving the adaptability of the system effectively is the key to reducing the vulnerability.
