城市绿地空间声景观优化机制研究

听觉是影响人环境感知的重要因素，优化声环境可以显著提升景观效果和整体功能。公园绿地不仅为游憩者提供隔离外界噪声的屏障，其营造特有的声、景要素共同影响着人的主观感受。文章在总结国内外相关研究的基础上，提出从绿地植物群落降噪及声环境要素调节两个方面研究绿地空间声景观优化机制，综合运用植物景观设计、噪声控制、环境心理学、声景观等多学科相关理论和研究方法，对促进绿地功能的发挥、指导植物景观设计、拓展声景观研究领域都具有重要科学价值。

Study on Soundscape Optimization Mechanism in Urban Green Space

Hearing is an important factor that affects people's environmental perception. It would improve the function and visual effect on condition that optimize sound environment. Green noise barriers in green space, as well as beautiful sound types, affect people's feelings through visual and acoustic factors. Based on the review of relevant research, the project worked over both the action on sound attenuation of plant communities and the constitutions of soundscape in green space, which was designed to explore the mechanism optimization of green space soundscape. To apply synthetically with the theories of planting design, noise control, environmental psychology and soundscape, it has important significance to promote the function of green space, enrich the theory and practice of planting design and expand research fields of soundscape.
