摘要
洪涝灾害是城市经济发展过程中面临的最主要灾害之一,研究城市经济发展对洪涝灾害承灾能力的影响具有重要意义。在分析经济发展带来新诱导因子的基础上,阐述了洪涝灾害、承灾能力的概念及关系,探讨了城市洪涝灾害承灾能力的影响因素,提出了新诱导因子房屋建筑施工面积对洪涝灾害承灾能力具有一定的影响。在分析安阳市经济发展状况的基础上,探讨了经济发展与房屋建筑施工面积的相关度,研究了典型年份生产总值、房屋建筑施工面积与经济损失之间的关系。结果表明:安阳市生产总值和房屋建筑面积同步增长,增长曲线呈"J"型,且二者相关系数为0.97。典型年份相对较少的降水却造成损失相对较大的经济损失,说明了房屋建筑施工面积等不透水面的增加相对削弱了城市的洪涝灾害承灾能力。
The flood disaster is one of the most important disasters faced in the urban economic development. It is of great significance to study the influence of urban economic development on the flood disaster carrying capability. The authors expounded the floods, the disaster-carrying capability concept and relationships, explored the influence factor on urban flood disaster-carrying capability, and put forward that new inducible factor such as housing construction area had some influences on disaster-carrying capability. On the basis of analyzing economic development of Anyang City, the article discussed the relevance of economic development and housing construction area. From this point, the authors studied the relationship among GDP of typical year, building construction area and economic damage. The results show that GDP and housing construction area have a simultaneous growth with each other, and the growth curve presents the type ＇J＇, and the correlation coefficient is 0.97 in Anyang City. In typical years, relatively smaller rainfalls have resulted in huge losses, suggesting that the increase of impervious surface relatively weakens the city＇s flood disaster-carrying capability.
