The Study Of Urban Design Optimization Method Combining With Climatic Conditions In Jinbo Island

The rapid development of city has brought great influence on the local climate environment.Favorable urban climate environment is one of important conditions that realize urban sustainable development.The urban design in the perspective of climate is an important issue that many researchers have paid attention to.Our country has vast land and urban climates differ in thousand ways.Related research has shown that the livability of the city Closely contacts with urban climate environment.The construction and development of the city is closely related to the shaping of favorable urban climate environment.The paper has set Liaodongwan New Town as an example,in summary,is based on internal and external studies on urban design in view of climate conditions.And the paper has used the methods of urban climate suitability analysis to having an knowledge of Liaodongwan New Town’s characteristics of the atmospheric environment.Above of all,the paper has try to providing a way of optimizing the urban space structure and building a good urban space environment。Firstly,the paper has taken the geographic information system platform.And then,different urban underlying surfaces and the land use information is added in the platform of GIS,analysising physical properties of city underlaying surface.At last,thermal load distribution figure and ventilation potential figure is got and the figures are the basis of the analysis of the urban climate suitability.According to the relevant planning information,the study has predicted that urban thermal load will be gathered in Jinbo Island in the future.Therefore,Jinbo Island is set the position of climate sensitive area.Secondly,in the medium,the paper has built windy corridor structure based on the results of Liaodongwan New Town urban climate environment analysis.Urban windy corridor is divided.Urban function space,climate ecological compensation space and the air guide channel is defined.Next,the paper is to optimize the urban windy corridor network in the perspective of building urban green network,layouting urban traffic network and satisfying the urban residents outdoor comfort.The scope of construction land is adviced.The development intensity is controlled.Reasonable mixed-use land is advocated.And then,Jinbo Island’s urban climate environment is proving.Thirdly,the paper has analyzed Jinbo Island’s urban climate environment elements via CFD,therefore,finding the problems in the zone and proving the designing scheme.Improvement Suggestions and optimization strategy are raised on account of CFD simulation results.Under the precondition of construction group layout principles connected with climate conditions,commercial building group space environment is improved,the layout of the residential area is optimized and greening related to climate suitability is decorated.In brief,the paper has researched the relationship between urban climate factors and urban space factors which including Green water system,road system and building layout in view of urban climate.According to urban climate information,Liaodongwan New Town’s urban climatic map that provides basis for Jinbo Island urban design is generated.
