Abstract

In urban green space (UGS), diverse acoustic resources are essential for enhancing the public’s well-being, as different sound sources can bring distinct auditory experiences. However, there is a lack of research on the sources-based soundscapes diversity (SSD). In this study, we fill this gap by exploring the characteristics of SSD in different recreational areas of UGSs across three urban gradients in Fuzhou City, China. Additionally, we investigated the relationship between SSD, landscape elements (LEs), and landscape patterns (LPs) at various spatial scales. Our findings identified 53 types of sound sources, predominantly biological sound and anthrophony. The alpha and beta diversity indices effectively characterized SSD in UGSs and captured the differences in three levels of urbanization. Our results showed that urbanization gradients significantly impact soundscape diversity, especially in terms of animal sounds and mechanical sounds. For LEs, we found that trees play a crucial role in enhancing the diversity of animal and recreation sounds, whereas the proportion of buildings negatively correlates with animal sounds. Our analysis between LPs and SSDs revealed a strong correlation between the built environment (mainly roads) and lawn with traffic sound. In contrast, a higher percentage of forest land was associated with more animal sounds and fewer recreational and mechanical sounds. Characterizing urbanization gradients and the factors affecting SSD can be used to guide the development and enhancement of soundscapes in UGS.

景观格局和景观元素如何影响基于声源的声景多样性
在城市绿地(UGS)中,多样化的声学资源对于提高公众的幸福感至关重要,因为不同的声源可以带来不同的听觉体验。然而,关于基于声源的声景多样性(SSD)的研究还很缺乏。本研究填补了这一空白,探讨了中国福州市三个城市梯度中不同休闲区的声景多样性特征。此外,我们还研究了不同空间尺度上 SSD、景观要素(LE)和景观模式(LP)之间的关系。我们的研究结果确定了 53 种声源,主要是生物声和人声。阿尔法和贝塔多样性指数有效地描述了 UGS 中的 SSD,并捕捉到了三个城市化水平的差异。我们的研究结果表明,城市化梯度对声景多样性有显著影响,尤其是在动物声音和机械声音方面。对于低地,我们发现树木在提高动物和娱乐声音的多样性方面起着至关重要的作用,而建筑物的比例则与动物声音呈负相关。我们对低地和高地的分析表明,建筑环境(主要是道路)和草坪与交通声音之间存在很强的相关性。相反,林地比例越高,动物叫声越多,娱乐和机械叫声越少。对城市化梯度和影响 SSD 的因素进行描述,可用于指导城市地质公园声景观的开发和改善。

期刊介绍: Urban Ecosystems is an international journal devoted to scientific investigations of urban environments and the relationships between socioeconomic and ecological structures and processes in urban environments. The scope of the journal is broad, including interactions between urban ecosystems and associated suburban and rural environments. Contributions may span a range of specific subject areas as they may apply to urban environments: biodiversity, biogeochemistry, conservation biology, wildlife and fisheries management, ecosystem ecology, ecosystem services, environmental chemistry, hydrology, landscape architecture, meteorology and climate, policy, population biology, social and human ecology, soil science, and urban planning.
