Abstract

In recent years, China's chemical industry, the rapid development of large-scale chemical enterprises gradually to scale, regional development, the construction of chemical enterprises gradually deepen the impact of urban public safety. Chemical layout layout dispersed everywhere phenomenon, the lack of unified planning, a lot of heavy chemical projects near residential areas; launched in the weak areas of resources, environmental carrying capacity, exacerbating the pressure on environmental resources; near environmentally sensitive areas, threatening the ecology of the original unreasonable of security ...... This layout, making the fire caused major disasters such as explosions and poison leak has occurred frequently, seriously jeopardize the safety of the entire city. Therefore, the study of the layout of the dangerous chemical companies that endanger the safety of the city is particularly necessary documentation requirements on more than stay in the qualitative research in this regard, the lack of effective operational planning, and therefore dangerous chemical enterprises need to establish a comprehensive optimize the layout and planning and site selection method. This article focuses on significant risk to the long-term threat to the safety of urban areas in the chemical enterprise class chemical companies, domestic and international land use safety planning research to carry out the city dangerous chemical enterprise security to optimize layout methods and procedures to solve the long plagued China's urban safety some complex and comprehensive technical difficulties, a fundamental solution to China's cities and security technology is relatively backward situation, and can actually be used in the planning of regional security, reducing the city to a new or existing level of risk of the chemical park. This paper summarizes past research on the basis of a dangerous combination of qualitative and quantitative chemical companies to optimize the layout. Through the collection of existing data, the combination of the safe distance of the different chemical companies, GIS buffer analysis of potential major hazard chemical companies in the city area, to evaluate land-use security status quo, to come to the relocation of dangerous chemical enterprises or rectification recommendations; same time, GIS spatial analysis techniques (such as: buffer analysis, overlay analysis, network analysis, etc.) on the use of land in the region for qualitative analysis, the feasible region can be used for site; then, using quantitative analysis method of fuzzy comprehensive evaluation Fuzzy comprehensive evaluation to select the location of the security, economic, social and other factors influence the risk of chemical companies, divided into different levels, and the expert scoring method is set to the corresponding value of the weights and the membership matrix after spatial analysis feasible domain to obtain the location of optimal decision for the relocation of dangerous chemicals enterprise rational layout planning views. Security layout optimized during the study in the area of ??land use, to break through the traditional subjective inference the only programmatic requirements of inadequacies, security planning for the city to provide a scientific and feasible the actual operational safety layout optimization method. The major hazard chemical companies extended by a single industrial park to the city as a whole, by the mere risk research extended to the site and optimize the layout. Dangerous chemical companies within a certain area of ??the city urban areas the security layout problems for the overall study, on the one hand, to adjust and optimize the layout to reduce overall risk within the region as a whole; the other hand, be able to provide for regional security of the city's layout planning guidance methods, to help the government carry out urban safety planning, and urban planning. This study to comprehensively improve the overall level of the urban areas of industrial production in security technology and scientific management, the major urban security decision-making, safety planning and the status quo level of safety and improving the reference and decision-making guidance, therefore, dangerous chemical enterprises security optimization the layout study has important practical significance and far-reaching social significance.
