Research Of Optimizing Layout Of Theshelter Engineering For Urban Residents Based On The GIS Technology

Civil air defense engineering is indispensable lifeline engineering to a city in the harsh times. Personnel shelter engineering is a very important part of civil air defense engineering system, but at present, there wasn’t any perfect theory as the guide to support the layout-design of personnel shelter engineering and mostly we make our decision by the planner’s experience rather than scientific and quantitative data which lead to some personnel shelter engineering have many kinds of problems after finished. People are eager to apply the new theory and technology to improve the layout-design defect at current of personnel shelter engineering, to make the layout more scientific and rationalization and improving the protective efficiency and ability of the engineering, at the same time, reduce the waste of resources.Along with the popularization of computer technology and the development and extension of GIS, GIS with all-round and multi-level is the development trend in urban planning in the future. However, if the new technology and new function of GIS could apply in the planning and layout-design of personnel shelter engineering in the future, it will provide more scientific date and quantitative index for the project’s planning and will enhance the rationality of layout-design of the personnel shelter engineering.Firstly, the article will briefly review the development of civil air defense engineering and the layout-design method of personnel shelter engineering, making a comparative analysis to summarize the defects and deficiencies of present layout-design of personnel shelter engineering; Secondly, there will be a analysis of the problems of the current layout-design of personnel shelter engineering; Finally, we will research the demand index, space layout and network connecting of city personnel shelter engineering with the GIS technology,meanwhile, we will use some examples to clarify this. Specific contents are as follows:1. The demand index of the personnel shelter engineering is determined by dynamic population distribution. Based on the simulation of the population and distribution on the time series, we can calculate the map of population distribution and the rule of population flow on the time series by GIS, and then analyze the index of sheltering people and the microscopic mechanism of engineering layout, determine the population of sheltering people, optimize the index of sheltering people.2. The space layout of personnel shelter engineering is an important factor that will impact the overall protection efficiency. It should be meet the requirements of personnel sheltering, optimize the sheltering area and quantitative index and improve the efficiency when use. Combined with the specific case, based on the GIS technolo gy, we can optimize the locations of the project and the scope of services, adjust and optimize the sheltering area and quantitative index, and build the general process of optimizing the layout of personnel sheltering engineering.3. The interconnection of personnel sheltering engineering can improve the efficiency of the engineering construction and sheltering. The principle of connecting come from the analysis of the benefit of personnel shelter connecting. Based on complex network theory to build netw ork model for personnel shelter engineering and study some specific cases. With the statistic of GIS and after calculating and analyzing several connected paths of the network in different connected scheme, we put forward the strategy of optimizing the network construction benefit.
