【摘要】 随着经济快速发展,人们对休憩环境的品质要求逐步提高,除了传统的视觉景观外,人们也越来越关注所处环境的声音品质,声景观的研究也随之兴起。如今公园作为承接人们放松休憩的场所,不仅要为游客提供绝佳的视觉景观,也必须在声景观上不断完善优化,更加全面地满足游客的愉悦身心的需求。成都市作为国内率先实行公园城市理念的城市,提出了“六大湖泊八大湿地”战略,本文选择其中之一的成都青龙湖公园作为研究对象。作为成都市内最大的湿地公园,成都青龙湖公园具有明蜀文化底蕴深厚,声景独具特色,公园使用者类型多样,公园外临近成洛大道、绕城高速、蜀都大道三条城市交通干道,声景观易受交通噪声影响。无论是从地处公园城市首提地的角度出发,还是从满足声景观研究必备的环境、人、声音三要素出发,对于成都青龙湖公园的声景研究都是必要的。本文通过实地调研、声景漫步、客观测量、问卷调查、数理分析等方法对公园的声景观开展了调查研究,通过主客观评价分析了公园的声景观现状,结合声景观设计手法对公园声景观优化提出了建议。首先在园区内选取了十二个极具代表性的景点,并依据地理位置和功能定位将其划分为出入口区、近高速区、东风渠区、文创园区。客观测量各景点和临近道路的交通噪声值,分析得出道路交通噪声对公园内龙舞花间、龙脊花径、花醉阁、望湖挑台四个景点的声景存在影响。其次构建问卷调查的评价指标后展开问卷调查。统计各区域的声景元素构成特征,得出公园游客声景偏好呈大区域统一,局部差异的特点:自然类声景深受喜爱,交通类声景则受到厌恶。主观评价中,东风渠区整体评价最高,近高速区则相反。运用SPSS软件论证了满意度作为综合性评价指标的合理性,并通过多元线性回归模型探究不同区域中其余指标对满意度的影响程度,发现主观响度只在东风渠区和近高速区两个区域对于满意度的评价存在影响,近高速区中喜好度影响最大,而另三个区域则是舒适度。最后利用声景观的设计手法,根据各景点的特征提出了对应的降低交通噪声、保护现有自然声景观、丰富人文声景的优化建议;结合声景观主客观评价结果和声景观满意度的影响因素,分别对四大区域的整体声景观提出具有针对性的优化途径。研究结果对于优化湿地公园的声景观和提升游客对公园的满意度具有一定的参考意义。更多还原

【Abstract】 With the rapid development of the economy,people ’s requirements for the quality of the rest environment have gradually increased.In addition to the traditional visual landscape,people are also paying more and more attention to the sound quality of the environment,and the research on the sound landscape has also emerged.Nowadays,as a place for people to relax,the park should not only provide tourists with excellent visual landscape,but also constantly improve and optimize the sound landscape,so as to meet the needs of tourists more comprehensively.As the first city to implement the concept of park city in China,Chengdu has put forward the strategy of " six lakes and eight wetlands." This paper chooses Chengdu Qinglong Lake Park as the research object.As the largest wetland park in Chengdu,Chengdu Qinglong Lake Park has a profound cultural heritage of Ming and Shu,unique soundscape,and diverse types of park users.The park is adjacent to Chengluo Avenue,Ring Expressway,and Shudu Avenue.Three urban traffic arteries,the soundscape is susceptible to traffic noise.It is necessary to study the soundscape of Chengdu Qinglong Lake Park,whether from the perspective of the first place in the park city,or from the three elements of environment,people and sound,which are necessary for the study of soundscape.In this paper,the soundscape of the park is investigated and studied by means of field investigation,soundscape walk,objective measurement,questionnaire survey and mathematical analysis.The current situation of the soundscape of the park is analyzed by subjective and objective evaluation,and some suggestions are put forward for the optimization of the soundscape of the park by combining the soundscape design techniques.Firstly,twelve representative scenic spots were selected in the park,and they were divided into entrance area,near high-speed area,Dongfengqu area and cultural and creative park according to their geographical location and functional orientation.Objectively measure the traffic noise value of each scenic spot and adjacent roads,and analyze the impact of road traffic noise on the soundscape of the four scenic spots in the park,including the dragon dance flower room,the dragon ridge flower path,the flower drunk pavilion,and the lake.Secondly,after constructing the evaluation index of the questionnaire survey,the questionnaire survey is carried out.According to the characteristics of soundscape elements in each region,it is concluded that the soundscape preference of park visitors is characterized by large regional unity and local differences : natural soundscape is deeply loved,while traffic soundscape is disgusted.In the subjective evaluation,the overall evaluation of Dongfengqu District is the highest,while the near-high-speed area is the opposite.This paper uses SPSS software to demonstrate the rationality of satisfaction as a comprehensive evaluation index,and explores the influence of other indicators on satisfaction in different regions through multiple linear regression model.It is found that subjective loudness only affects the evaluation of satisfaction in Dongfengqu District and near-high-speed District,and the preference in near-high-speed District has the greatest impact,while the other three areas are comfort.Finally,using the design method of soundscape,according to the characteristics of each scenic spot,the corresponding optimization suggestions are put forward to reduce traffic noise,protect the existing natural soundscape and enrich the humanistic soundscape.Combined with the subjective and objective evaluation results of the soundscape and the influencing factors of the soundscape satisfaction,a targeted optimization approach is proposed for the overall soundscape of the four major regions.The research results have certain reference significance for optimizing the soundscape of wetland parks and improving tourists ’ satisfaction with the parks.更多还原
