Study On Soundscape And Upgrading Design Of Jincheng Greenway Phase One In Chengdu

Urban greenway has the functions of leisure,entertainment,communication,ecology,etc.It is part of the belt park in the urban green space system.As one of the first choice of recreation and entertainment places for residents,its landscape has always been concerned,but the existing urban greenway construction is too pursuit of ecological benefits and often ignores the influence of cultural factors on the greenway,resulting in low public participation.With the improvement of the awareness of environmental protection,the study of soundscape is gradually emerging in China,and relevant scholars and designers have realized the impact of soundscape on greenway landscape.Research on the Jincheng greenway phase one issue,can reveal the city green way voice users and the environment in the three intrinsic relations,it is beneficial to the renewal and development of existing greenway soundscape and can solve the main contradiction of sound environment in the development of urban greenway to a certain extent,to make the acoustic environment more in line with the psychological needs of the public,so as to improve the use of greenway.The integration of quantified acoustic research technology improves the precision of greenway soundscape research.Based on the objective understanding of the greenway soundscape through the literature analysis,the investigation and analysis of the soundscape of Jincheng greenway phase one were carried out.In the process of field investigation,the acoustic parameter measurement method and questionnaire survey method are combined to interpret the existing soundscape and analyze the performance of greenway acoustic environment in subjective and objective contexts.On this basis,the differences of greenway soundscape in the two contexts are analyzed,the advantages and disadvantages of greenway soundscape are analyzed,and put forward the current situation of Jincheng greenway phase one soundscape problem,and use the macro and micro methods to improve the design of the sound landscape of the south section of Jincheng greenway..The following main results and conclusions are drawn,First,due to its geographical location,the Jincheng greenway phase one has a lack of sound comfort,so it is necessary to improve the sound scene scientifically and rationally,properly deal with the environment,people and sound,the relationship between the three.Second,under the influence of many factors,the Jincheng greenway phase one forms the feature of dotted and linear distribution in space,and becomes the characteristic of greenway soundscape.Thirdly,on the whole,greenway tourists have a high expectation of quiet acoustic environment,and the coordination of passive acoustic interference and acoustic function is the main factor causing the difference of acoustic environment.Fourth,the comprehensive function of multi-elements and multi-types of soundscape forms a greenway space with rich layers and multi-sensory coordination.The sound environment should be paid attention to and should be integrated into the design rather than optimized.Through the study of Jincheng greenway phase one soundscape,this paper provides a more scientific and objective research idea in the analysis of greenway soundscape,which plays an important role in the improvement of existing urban greenway soundscape,to some extent,it can promote the innovation of soundscape research methods,and update the design principles and methods.
