Study On The Theory And Method Of Extension Urban Comprehensive Disaster Prevention Planning

In recent years,urban disaster prevention has become hotspot in the research of urban and rural planning area.As the statutory special plan of the urban master planning,urban comprehensive disaster prevention planning is an important part of the urban master planning.This research is an intersecting studying issue of extension theory and urban comprehensive disaster prevention planning,which offsets the deficiency in the theory and method of urban comprehensive disaster prevention with the advantages of extension theory.This paper constructs the theoretical framework of extension urban comprehensive disaster prevention planning from the research orientation,type division,basic principles and other aspects and put forward the corresponding application method system for the contradiction problem in different types of disaster prevention planning,which provides a theoretical support and method platform for intelligent computer-aided urban comprehensive disaster prevention planning generation strategyThe extension urban comprehensive disaster prevention planning means that in the process of making the plan,the comprehensive disaster prevention planning compilers and decision-makers apply the theory of extenics and its model thinking and logical reasoning,resolve the incompatible problems and the conflict of opposites and put forward innovative ideas and specific solutions of the activities and processes through the extension analysis and transformation of the objectives and conditions of disaster prevention planning.Its basic principles include basic element expression,extension thinking mode,extension analysis and extension transformation of the urbn comprehensive disaster prevention planning.The operation process includes four steps: the definition of disaster prevention planning,the analysis of objectives and conditions,the transformation of disaster and disaster prevention elements,and the generation and evaluation of strategies.The type can be divided into the single disaster-oriented(fire-led,flood-driven type is the typical representative)and multi-disaster coexistence type.Methods of fire leading extension urban comprehensive disaster prevention planning use extension methods to solve the contradictory problems in the comprehensive disaster prevention plan dominated by fire and supplemented by the other planning.For multi-method of fire leading comprehensive disaster prevention planning,the strategy generating methods of meeting all types of the firefighting planning objectives including two respects: meeting the fire code and meeting the master planning goals.For the whole process of fire leading disaster prevention planning,the research puts forward extension design methods to promote efficiency of firefighting planning from three processes including the fire rescue,the fire prevention and the reconstruction after fire.For the different functional requirements of fire sites and facilities at ordinary and disaster times,the research puts forward transforming bridge method of implementing the integrated disaster prevention in the firefighting planning from the planning and design of hazardous land and fire water supply facilities.Methods of flood control leading extension urban comprehensive disaster prevention planning use extension methods to solve the contradictory problems in the comprehensive disaster prevention plan dominated by flood control and supplemented by the other planning.For multi-method of flood control leading comprehensive disaster prevention planning,the strategy generating methods of meeting all types of the flood control planning objectives including two respects: meeting the flood control standard and meeting the river basin flood control target.For the whole process of flood control leading disaster prevention planning,the research puts forward extension design methods to promote efficiency of flood control planning from three processes including the prevention before the flood,the evacuation in the flood and the reconstruction after the flood.For the different functional requirements of flood control sites and facilities at ordinary and disaster times,the research puts forward transforming bridge method of implementing the integrated disaster prevention in the flood control planning from the planning and design offlood control channel and flood wetlands.Methods of multiple disaster coexistence extension urban comprehensive disaster prevention planning realize defensing multiple disaster and secondary disasters together dominated by earthquake on the basis of single disaster leading extension urban comprehensive disaster prevention planning methods.At first,the research puts forward the multiple disaster coexistence disaster planning problem generating including evaluation of urban disaster risk and disaster prevention ability,collection and classification of the multiple disaster defense problem and extension model expression of the multiple disaster defense problem.Secondly,the research puts forward the channel switching of multiple disaster coexistence disaster planning problems including containing channel of multi-disaster disaster prevention target and transformation channel of multi-disaster disaster prevention conditions.At last,the research puts forward the multi-objective strategy generation of multiple disaster coexistence disaster planning including transforming bridge strategy generating of urban comprehensive disaster prevention detailed planning and fuzzy matter-element strategy generating of urban comprehensive disaster prevention overall planning.The paper also discusses the design principle and the preliminary framework of the strategy generation system for the extension urban comprehensive disaster prevention planning.In a word,the theory and method of extension urban comprehensive disaster prevention planning is a intersecting studying issue of extenics,urban comprehensive disaster prevention planning and urban special disaster prevention planning,which constracts theoretical framework for extension urban comprehensive disaster prevention planning,and proposes the method of extension urban comprehensive disaster prevention planning to solve the practical problems in urban comprehensive disaster prevention plan and improve the level of compilation and decision-making in urban comprehensive disaster prevention planning.Firstly,this research adds new theories and methods for urban comprehensive disaster prevention planning area.Secondly,it provides forming tools for describing urban comprehensive disaster prevention plan strategy generation process.Thirdly,it provides theoretical basis and technical support for artificial intelligent process of urban comprehensive disaster prevention planning.At the same time,it expends applied range of extenics in urban disaster prevention planning area.
