Study On Impact Evaluation And Improving Suggestions Of Acoustic Environment Of The Commercial Facilities In Guangzhou Baiyun Mountain Scenic Area

Baiyun Mountain is a famous scenic spot of Guangzhou and also is a great place for people to have relaxed. There are a lot of entertainment-based commercial facilities in the scenic spot which include catering and shopping store, and it plays an important role in the meeting of the growing wealth of tourist excursions. Although these commercial facilities do a great convenience for tourists to have relaxed, it affects of the sound environment quality of the scenic spot. Though the Scientific assessment of the impact of commercial facilities to the Baiyun Mountain scenic quality of the acoustic environment, and explore its rational planning and standardized management policies, all this actions above will be great beneficial strategies to protect Baiyun Mountain "impressive" scenic resources.In this paper, writer used the "national scenic area- Baiyun Mountain Scenic Area, Guangzhou City Master Plan(2009-2025)" conservation objectives: conservation partition as the basis. With the reference of the US National Park sensitive gradient sound planning theory, writer classified the types Conservation Area of Baiyun Mountain into highly sensitive areas, sensitive areas, low-sensitive and non-sensitive areas, according to the human activities sound sensitivity to the environment. And also according to the plan status and layout features of commercial facilities in Baiyun Mountain, writer selected the "Po Valley restaurant", "nine Longquan Business point ", " Urban Construction Forestry canteen ", " Peak Galleria " and " extreme sports center, " these five typical commercial facilities as study objects of the paper. Also writer studied the sound environmental of these five types of commercial facilities spot, through the combination of study methods which included field notes, recordings analysis, physical measurements and questionnaires. The results of study shows as followed:1. Baiyun Mountain sound pressure level of the commercial facilities in the touring spot reached to 60 d BA or even more which are much higher than the peak of sound environmental control standards of the scenic area of 50 d BA. However, less SPL in commercial activity in general basic compliance period which indicated that the commercial facilities background sound is a main reason lead the sound pressure significantly increased.2. The questionnaire survey shows that most visitors affirmed the necessity of a commercial facility and higher degree of acoustic comfort evaluation of the commercial point which are different from the objective assessment of the results. This contradiction indicated that SPL standards as the basis for sound environmental control standards Baiyun lack of operational sound environmental management, sound environmental impacts of commercial facilities have yet to be explored further.3. According to the site records and questionnaire survey, the "background music", "sound of machinery and equipment", "car sound" and "talk laughter" are great sound impact elements to the commercial facility acoustic environment. Scientific planning site, optimized space layout, specification audio equipment as well as a reasonable guide the tourists’ behavior are the main direction of improving the sound environment of commercial facilities spots.Based on the above analysis of the survey results, integrated the conservation objectives of Baiyun Mountain overall plan, this paper try to improve the baiyun mountain acoustic environment of typical commercial facilities with the specific recommendations. Recommendations list as followed:1. Though the loudspeaker management and changing the visiting trail routs as well as optimizing operation mode of restaurant to improve the Po Valley sound environment.2. Nine Dragon Fountain business spot can improve sound environment though optimizing the background music and zoning management as well as leading the behavior of visitors into sound environment protection action.3. In urban forest canteen spot, the management department is recommended to shunt the visitors’ branch of the site and improve the material of the appliance as well as loudspeaker management to improve the sound environment.4. Through proper site design strategy, tourists activities guidance and standardized manage of site to improve the park of mountaintop sound environment.5. Extreme sports center can unified the loudspeaker management and decrease the noise of mechanical equipment, also tourists activities guidance to improve the sound environment This study clarified the effect of a typical commercial facilities Baiyun Mountain scenic acoustic environment, and made management recommendations to regulate the sound environmental of commercial facilities resorts for enhancing the comprehensive the scenic quality of the environment and also it is significant to carry out soundscape protection action to improve the sound environment of Baiyun Mountain.
