Study On Seismic Disaster Prevention Zoning Of Central Urban Area Of Donghai County City

The earthquake is one of the natural disasters which have been difficult to avoid so far. Since the last century, many countries in the world have entered the earthquake prone period. Such as domestic Wenchuan, earthquake in Ya'an, abroad in Japan's Kanto, Hanshin earthquake, the Northridge earthquake and the Indian Ocean earthquake and tsunami in. With the frequent occurrence of earthquake disasters in the world, it is difficult to avoid the phenomenon of natural disasters, so that the construction of a safe city has become the focus of attention of all countries and cities in the world. And our country should strengthen the city's emergency rescue ability after the earthquake, as far as possible, to the greatest extent possible to reduce the impact of the earthquake to the city and the people.Now China's many large and medium-sized cities has entered the stage of accelerated urbanization, compared with the past, many small cities have also entered the stage of accelerated urbanization, population and construction units for the urban land aggregation degree higher than at any time in the past. In this case, once the occurrence of a large earthquake disaster, the city and the people's lives and property will have a huge impact on the destruction and. And to the city for seismic disaster prevention subarea and can make the city formed a more suitable space layout, which is not only conducive to the next development of urban earthquake disaster prevention planning, but also conducive to the city to maintain a good social order and the ecological environment, because seismic disaster prevention partition can effectively prevent some secondary disaster sprawl. In a large extent control earthquake generated adverse effects.Therefore, this paper in order to form a reasonable seismic disaster prevention division, to enhance the city's capacity for the purpose of seismic disaster prevention, from the perspective of urban space, the use of a variety of planning methods to expand the city's seismic disaster prevention zoning. In combing the domestic and foreign related research progress, the central place theory, public facility location theory, neighbourhood and community theory as the basis, the related factors of urban earthquake disaster prevention subarea were detailed analysis. Then in Donghai County, the center city as the research object, combined with status and related influencing factors analysis, make the division of seismic disaster area and earthquake disaster prevention group, making the city to better based on the capability of earthquake resistance and disaster prevention, but also for the other same type of city earthquake disaster prevention planning to provide a scientific reference.
