Management and Planning of Natural Tranquility of Protected Area Based on Spatio-Temporal Distribution Characteristics of Soundscape Resources

As a natural resource, soundscape is of great significance to the ecosystem. In order to further protect the integrity of the ecosystem in protected area, the local acoustic environment needs to be managed and utilized rationally. The existing acoustic environment researches in China focus on the built environment, and the approaches of planning and managing the protection of the acoustic environment are yet to be deeply studied. With reference to the international advanced soundscape planning and management experience, this research studies relevant cases in the United States and European countries with spatial-temporal distribution as a cutting point. It also proposes planning management policies citing the Yunnan Dashanbao Nature Reserve as a practical case. It puts forward a method to control the acoustic environment of the protected area based on the characteristics of the current soundscape spatial-temporal distribution. It also raises for the first time in the country the corresponding management indicators and thresholds for the acoustic environment of natural reserves. The research can provide a reference for the management of the acoustic environment in protected area, and it is also of reference significance for the establishment of acoustic environment standards in areas with ecological protection value in the territory planning.
