Level Disaster Combined City Park Disaster Prevention Transformation Of Design Research

City is a fragile carrier witch have limited resistibility to fight against disaster,the citywill suffer a devastating blow and irreparable damage when disaster happens. Disasterpreventional parks which ensues normal development of rescue and relief can providespace for evacuation、escape、medical rescue，they can also be temporary buffer witch areused for rebuilding city. However, in circumstance of land shortage,we can remould cityparks for combining disaster prevention function and amusement function,this method cansave building space、relieve land shortage、reduce construction investment、shortenconstruction period，for those reason,it is very important to reconstruct city parks fordisaster prevention.At first,based on substantial literature,this article elaborates the conception of urbandisaster, summarizes the reasons、types and characteristics of urban disaster;this article alsoputs forward the conception that amusement space with disaster prevention function,thisviewpoint is based on the real emergency shelter and disaster evading greenbelt;Furthermore,this article analyses kinds of behavioral characteristics and psychologicalfactor about people who is facing Escape selection.Secondly, this article elaborates the researchings about disaster preventionalconstruction witch incudes the disaster preventional urban plan of western country,theoryand construction of disaster preventional park in japan,and the disaster preventionalconstruction of china.Thirdly,this article defines the conception of urban disaster preventional park by usingthe advanced plan of western urban disaster prevention and experiences of Japanese disaster preventional park construction,this article makes qualitative analyses (types andfunctions of disaster preventional park)and quantitative analyses(service radius、 pereffective safe area and effective safe area),summarizes the content and standard of disasterpreventional park,points out the weaknesses of shelter in china,analyzes the compatibilityof ordinary and disaster preventional park. This article summarizes advantages ofremoulding urban park with the situation of land shortage in china,puts forwardremoulding urban park and greenbelt by using the conception of combining amusementfunction and disaster prevention function.At last,this article analyzes the content ofremoulding disaster preventional park in details,the major analyzed object includesentrance space、road、buildings、helipads、water、square、plant configuration and so on.Finally,taking example for disaster preventional remoulding of Tianjin Changhongecological park,this article analyzes the traffic condition、service object、field condition、disaster preventional quotas,introduces the content of ecological park remoulding,researches the entrance、road、buildings、emergency facilities of ecological park,putsforward questions about park remoulding with relative theory to offering help aboutdisaster preventional construction at future.
