The Research About Space Planning Of Medium-Sized City In Prevention Of Geological Disasters

With the development of society and economy,the level of urbanization in our country continue to improve,but all kinds of city disaters occur frenquently,especially the earthquake.The earthquake presents a major challenge to safety of the city.Most cities in our country there are varying degrees of geological disaster situation,and the development of the city is also bound to change the original geological conditions and induce the geological disasters.The planning of urban disaster prevention has an important role and positive significance.This thesis preliminarily studies the planning of urban disaster prevention from the perspective of urban planning,and finds a effective way to control urban disaster.It starting from understanding the basic concepts,researching the basic types of geological disasters and to the main target for the earthquake,analyzing the role of urban green space,traffic space and underground space for disaster prevention,and according to the requirements of urban disaster prevention,to explore the construction of city disaster prevention park,the improvement of the anti-relief channel,the use of underground space the city has had,and the application of city lifeline system.All of these aim to reduce the losses and casualties of geological disasters.Finally,studying the spatial planning of urban disaster prevention to Jin Zhong city as an example.Jinzhong city has serious geological disasters,through surveys and analysis,the author devides geological disaster-prone region,transforms urban green space system to increase the construction of city disaster prevention park,reorganizes city roads to improve the disaster prevention construction channel,and generally considers urban water supply,electricity,gas,and communication systems for disaster prevention requirements to improve city lifeline systems.
