Research On Earthquake Risk Analysis And Space Planning Of Disaster-prevention

As a huge exposure,cities are gradually becoming the center and emphasis of disaster prevention among international community. It becomes a very practical and challenging issue to reduce the earthquake risks and improve earthquake disaster management capability. Also, urban earthquakes which happened at home and abroad in the history prove the importance of urban disaster-prevention.With the rapid development of Chinese economy and the improvement of urbanization, the density of urban construction on each land unit is higher than ever before. In this case, if disasters take place, they will result in obvious amplification effect. Therefore, reasonable arrangement of urban space will benefit the improvement of ecological environment of cities, reducing disasters, controlling their spread and lessening disaster risks. So this article mainly researches around earthquake risk management and the planning of urban space disaster-prevention.First,the planning of the disaster-prevention of urban space structure must build on the basis of the research of urban disaster risks. Unless we know the type of the disaster and the extent of the risk, we can make plans aiming at them. This thesis will focus in particular on earthquakes, and will research urban earthquake risk management, the procedure of this, and other related topics.Secondly, this article researches the planning of the disaster-prevention of urban space structure. Proceeding from the essential factors of the disaster-prevention of urban space structure, this article builds a network of disaster-prevention of urban space structure, divides the disaster-prevention of urban space unit into three levels and integrates them, so every disaster-prevention of urban space can exert the effect of disaster-prevention and disaster-reduction more effectively.Thirdly, the research on the strategy of disaster-prevention of urban space structure for every level is the stress of this thesis. It proceeds from three levels of disaster-prevention of urban space structure, combines the procedure of urban disaster-prevention, and aims at the strategy of planning disaster-prevention space differs at different levels.In the last part, this article put forward some assumption and suggestion of Qinhuangdao disaster-prevention of urban space system.
