摘要
随着城市化水平的不断发展,人们对安全、生态、环境等的需求也在持续提高,防洪安全作为城市安全领域中最重要一环,对于城市的存在与发展具有决定性意义;历经多年规划建设,大部分城市都具备了基本的防洪能力,同时也存在着诸多薄弱环节,如人口密度大、资产集中度高、基础设施差等,均导致在面临洪涝灾害时会发生不可避免的损失。通过城市洪涝易损性评价,可以对城市防洪的薄弱区域、环节开展针对性防治措施。运用陈守煜教授等人提出的可变集理论及其洪涝易损性评价方法,构建适合于北京地区的评价指标体系与评价标准,考虑数据的可获取性,以行政区划为单位对北京市16个行政区开展评价,分析其存在的问题及原因,提出相应的建议。
With the continuous development of urbanization,people's demands for safety,ecology and environment are also continuously improving.Flood control safety,as the most important link in the field of urban safety,is of decisive significance to the existence and development of a city.After years of planning and construction,most cities are equipped with basic flood control capacity.Meanwhile,there are many weak links,such as large population density,high concentration of assets and poor infrastructure,which lead to inevitable losses in the face of flood and waterlogging disasters.Targeted prevention and control measures can be carried out for the weak areas and links of urban flood control.Using the variable set theory and the method of flood vulnerability assessment put forward by the professor Chen ShouYu,then build the suitable evaluation index system and evaluation standard for Beijing area,considering the availability of data,the administrative divisions in unit 16 administrative region in Beijing to evaluation,analyzes the existing problems and reasons,put forward the corresponding suggestion.
