快速城镇化典型衍生灾害防治的规划设计原理与方法

Based on the digital technology and fused with multi-disciplinary theory achievement, this subject regards the rapid urbanization area as its research object, and it will research the spatial structure evolution, the typical disaster derivative mechanism, the spatiotemporal coupling relationship, and the occurrence regularity; explore the principles and methods of urban planning which prevent disasters caused by unlimited sprawl, environment deterioration, high-strength exploitation, and high risk agglomeration; optimize the theory of disaster prevent space and shelter layout under the high-density condition. Meanwhile, in view of the construction security issues under complex terrain and geological condition, the subject will explore the typical urban geological disaster prevention planning measures, and it will also innovate the technique methods of microclimate environment improvement and urban waterlogging disaster prevention. Further more, the subject will construct the control theory by digital technology, form the systematic disaster-prevention planning technical specifications and design guidelines, and make planning practice and engineering demonstration. It will provide a solid theoretical basis for the typical urbanization derived disasters prevention and the constructive destruction prevention..This subject is the frontier research topic that will make up the lack of disaster prevention planning theory under the background of new urbanization. And it has great significance and theory value in the respects of ensuring the strategic security of cities, the implementation of new urbanization strategy, eliminating catastrophe threats and protecting the life and property security, and promoting the development of urban planning discipline and science progress..
