【摘要】：城市化是人类社会未来发展的必然趋势,也是一个国家走向现代化的必经阶段,而石油化工产业在城市化进程中扮演着不可或缺的重要角色。随着我国经济的快速发展和产业结构的优化调整,具有产业集聚效益的大型化工园区纷纷涌现。化工园区聚集着各类化工企业,重大危险源数量多,一旦发生火灾事故,容易导致重大人员伤亡和财产损失,甚至造成恶劣的社会影响。为了提高化工园区的消防安全水平,必须在宏观上准确把握化工区内各区域的整体火灾风险水平,从而制定科学合理的消防规划。因此,研究化工区的火灾风险大小,对大型化工园区进行火灾风险评估,具有重要的学术价值和社会价值。本文以天津市滨海新区南港化工区为研究对象,在充分调研、统计相关数据的基础上,借助GIS强大的空间数据和属性数据的管理功能建立了南港化工区GIS数据库,分析了南港化工区的主要危险源,并结合其特点和现有数据条件,建立了南港化工区火灾风险评估指标体系,用层次分析法(AHP)确定了各指标的权重,通过GIS强大的数据分析能力,得出了南港化工区的火灾风险评估结果图,确定了园区的整体火灾风险水平等级,从而为化工园区的发展和现状改造提供科学的指导,同时也有助于确定和排除重大的火灾风险隐患。本文借助GIS的强大数据管理和空间分析能力,对化工区进行火灾风险评估,相比于传统的统计方法,具有可操作性强、方便实际应用等特点,并用实例证明了GIS在火灾风险评估领域的优越性。
[Abstract]:Urbanization is the inevitable trend of the future development of human society, and it is also the necessary stage for a country to move towards modernization. The petrochemical industry plays an indispensable role in the process of urbanization. With the rapid development of China's economy and the optimization of industrial structure, large chemical industrial parks with industrial agglomeration benefits have emerged. There are many kinds of chemical enterprises in the chemical park. Once the fire accident occurs, it will easily lead to heavy casualties and property losses, and even cause bad social impact. In order to improve the level of fire safety in the chemical industry park, it is necessary to accurately grasp the overall fire risk level of each area in the chemical industry area and formulate a scientific and reasonable fire control plan. Therefore, it is of great academic and social value to study the fire risk in chemical industry area and to evaluate the fire risk of large chemical industry park. In this paper, the Nangang Chemical Industry District of Binhai New District of Tianjin is taken as the research object. On the basis of full investigation and statistics, the GIS database of Nangang Chemical Industry District is established with the help of the powerful management function of spatial data and attribute data of GIS. In this paper, the main hazard sources in Nangang Chemical Industry area are analyzed, and the fire risk assessment index system of Nangang Chemical Industry District is established by combining its characteristics and existing data conditions. The weight of each index is determined by the Analytic hierarchy process (AHP). Through the powerful data analysis ability of GIS, the result map of fire risk assessment in Nangang Chemical Industry area is obtained, and the overall fire risk level of the park is determined, thus providing scientific guidance for the development and current situation of chemical industry park. It also helps to identify and eliminate major fire risks. With the help of the powerful data management and spatial analysis ability of GIS, this paper evaluates the fire risk in chemical industry area. Compared with the traditional statistical method, it has the characteristics of strong maneuverability, convenience for practical application, and so on. The superiority of GIS in the field of fire risk assessment is proved by an example.
