摘  要：
基于突变理论,选取城市人口状况、城市经济状况、生命线工程状况、城市环境状况等指标,构建洪涝灾害易损性评价指标体系。在理论分析的基础上,将评价模型应用于广东省潮州市湘桥区2000—2010年洪涝灾害易损性综合评价中。结果表明,湘桥区洪涝灾害承灾体易损性在波动中有所减小,其易损性变化有两个转折点,分别是2004和2008年。影响承灾体易损性变化的主要因素是人口自然增长率和建成区绿化覆盖率。可以通过以下途径降低该区洪涝灾害易损性:(1)控制人口增长速度;(2)增加建成区绿化覆盖率;(3)增加排水管网密度。

摘  要：
Based on catastrophe theory,an evaluation system of flood disaster-bearing bodies' vulnerability was constructed by indexes of the conditions of population,economy,lifeline engineering and environment.Then,the model was used to evaluate the vulnerability in Xiangqiao district in Chaozhou City of Guangdong Province during 2000 to 2010.The results showed that vulnerability in Xiangqiao district decreased in fluctuation,and it had two turning-points in 2004 and 2008,the main influencing factors of which were population growth and vegetation coverage rate.Several measures should be taken to reduce the vulnerability of flood disaster-bearing bodies in the study area,which include to control the increase of population,to increase the coverage of vegetation,and to increase the density of drainage pipe network.
