Research On The Characteristics And Optimization Strategies Of Soundscape Of Miao Settlements In Southeast Guizhou Under The Background Of Tourism Developmen

The acoustic landscape is an important part of the landscape environment of the Miao nationality settlement.many achievements in the visual perception research,but still some deficiencies in the sound perception research,especially in the regional characteristic sound experience.special soundscape is an important channel for users to perceive the traditional Miao culture,the study of its soundscape features has the practical significance of protecting traditional culture,increasing tourism features and improving people’s quality of life.The progress of science and technology and the process of urbanization have deepened people’s perception of space,but the accelerated pace of production and life has led to the destruction of the characteristic space environment and the emergence of man-made noise,make the sound environment deteriorating,noise nowhere to hide and sound heritage is disappearing.The sound source of capital pursuing profit and industrialized production tends to be homogeneous,which makes people tired of aesthetic appreciation,and at the same time,their thirst for the characteristic sound source is constantly strengthened.In order to further excavate and protect the characteristic soundscape resources and improve the quality of people’s living sound environment,this paper focuses on the Miao settlement in the context of tourism development,combining historical documents,official websites and field surveys,this paper probes into the historical background,present situation and optimization strategy of the Miao settlement in southeast Guizhou from various directions and angles,and the main work of the paper includes the following aspects:(1)Survey: through historical documents and literary works,this paper reviews the historical background of the Miao settlement in southeast Guizhou,and extracts the signature sounds with regional characteristics,through the official website and literature,this paper combs the distribution situation under the background of tourism development in southeast Guizhou,the situation of selected traditional villages and ethnic minority villages in China,the basic information,culture and landscape characteristics of Miao settlement under each development background,in this way,the typical research area is selected.(2)The basic characteristics of soundscape were investigated and analyzed:according to the principles of national oneness,the representativeness of the settlement,the accessibility of the investigation,the representativeness of the space,the regionality of the soundscape,etc.,the physical environment test and soundscape perception evaluation of the Miao settlement were carried out by means of sound walk method,and the acoustic,physical environment and objective visual characteristics of different development degrees and topographic functional conditions were summarized,the factor analysis method is used to obtain five perception latitudes of sound scene and three perception latitudes of visual scene.(3)Case Studies: in-depth study of selected typical case Xijiang thousand Miao village based on preliminary findings,using grid method and landscape block method,combined with field measurement and evaluation questionnaires,the spatial and temporal distributions of Xijiang thousand Miao village data were recorded in detail,and the interpolation analysis was carried out with the help of GIS(Arc GIS 10.2)platform.The Objective Xijiang thousand Miao village included 243 grid points in the main visiting residential area and the subjective Xijiang thousand Miao village included21 landscape patches in the main visiting residential area,the loudness,frequency,preference,subjective perception evaluation and physical sound pressure level of soundscape elements in different time periods were collected.The spatio-temporal variation and interrelation of subjective and objective data of Xijiang thousand Miao village soundscape were analyzed.(4)The optimization strategy is mainly based on the principle of soundscape optimization,the idea of optimization and the specific optimization strategy of typical cases,on the premise of not destroying the original landscape of the Miao settlement as far as possible,the optimization strategy is put forward based on the idea of sustainable development of soundscape.
