摘要
城市声景观是体现城市特色的重要方面,然而城市声环境不断恶化,如何保护那些具有城市特色的声景观成为了亟待解决的问题。文章以天津为研究蓝本,利用声漫步的方法探讨了值得保护的城市声景观的特征及其保护的重要性。结果发现描述值得保护的声景观特征因子分别是:放松感、活力度、代表性、强度以及丰富性。在此基础上,采用层次聚类法可以将值得保护的声景观分为五类,不同类别声景观保护重要性之间存在显著的差异,其中活力度较高的自然类声景观保护重要性最高。最终,根据声景观的特征及其保护重要性提出了相应的保护策略。
Sound environment is essential for improving the overall quality of the urban environment and for reflecting the characteristics of a city. Therefore, how to preserve the urban soundscapes has become an urgent problem. Based on the example of Tianjin, China, this study aims to identify the characteristics and preservation importance of urban soundscapes worthy of preservation. It is found that relaxation, vibrancy,representativeness, strength, and richness were principal factors that characterize the soundscapes worthy of preservation. Based on their characteristics, these soundscapes were classified into five clusters using Hierarchical Cluster Analysis(HCA). Afterwards, the preservation importance of different clusters of soundscapes were explored and some corresponding preservation strategies were put forward.
