浣花溪公园不同景观空间下的声景观特性研究

该文以成都市浣花溪公园为研究对象，通过对景观空间中声环境的综合研究探究其声景观特性，以此作为营造城市声环境的有效依据。文章首先通过声压级、声景观多样性指数和清晰度指数来定量探讨公园中17种景观空间下的声环境异同；然后以声景观舒适度指数和重要性-满意度-清晰度模型对12种声音类型进行主客观评价；最后通过声景观提升指数综合反映各景观空间下声景观的提升重点。研究发现，声景观会受到基底-覆盖-围合层面的不同类型和组合的影响，尤其在建设面开敞和绿色半开敞或绿色半封闭空间中得到社会声和自然声最为明显；声景提升应重点关注风声、鸟声、水声、昆虫声和音响声在对应景观空间中的利用。

A study on the characteristics of acoustic landscape in different landscape Spaces of Huanhuaxi Park

This paper takes Huanhuaxi Park in Chengdu as the research object, to study their soundscape characteristics through the comprehensive consideration of landscape and soundscape space. I hope that can be used as an effective basis for creating a good soundscape. This paper is mainly divided into three parts: First, the similarities and differences of sound environment in 17 kinds of landscape spaces in the park were quantitatively discussed by means of sound pressure level, sound landscape diversity index and clarity index. Second, the comfort index of soundscape and the model of importance-satisfaction-clarity are used to evaluate 12 sound types subjectively and objectively.Finally, through the soundscape improvement index, it comprehensively reflects the main promotion focus of soundscape under each landscape space. It is found that the soundscape there is affected by different types and combinations of basement-covering-enclosed layer, in which social sound and natural sound are dominant in the construction of open and green semi-open / semi-enclosed spaces respectively; soundscape enhancement should focus on the utilization of wind, birds, water, insects and sound equipment in corresponding landscape space.
