人工声能反映公园游客的活动模式和规律,具有重要研究价值.夏季人工声具有丰富度高、发声集中等特点.文章选择福州不同城市化水平的3个城市公园,采集夏季声学数据并使用声学指数进行量化,探讨人工声时空变化特征与公园景观格局的关系,旨在为城市声环境管理和公园设计提供科学依据.结果表明:1)福州夏季城市公园的人工声主要分为城市背景声、管护声和游憩声,分别源于公园外部、内部和游人活动.2)人工声的时间异质性主要由城市居民的活动所驱动,呈现夜晚低、白天高的趋势;空间异质性受公园区位、园内设施、节点分布、斑块性质影响.3)公园景观格局对人工声的频次与时长有显著影响,管护声和交通声随着灰色空间的增加而增加,而林地面积的增加能够提高游憩声的频次和时长;NDSI指数与林地的景观格局指数呈负相关,与灰色空间的景观格局指数呈正相关.研究结果说明公园内的林地对于减少人工声干扰具有积极作用,据此提出未来城市公园人工声景优化策略,即增加公园边界的缓冲区面积和种植垂直层次的植物、合理规划公园内部分区和道路系统、在人工声干扰高的区域设置一定的声景干预等.
Relationship Between Spatial-Temporal Variation Characteristics of Anthrophony and Landscape Pattern in Urban Parks in Summer
Anthrophony can reflect the patterns and laws of park visitors'activities,which has important value for research.Anthrophony in summer is characterized by high richness and concentrated vocalization.The paper selects three urban parks at different urbanization levels in Fuzhou to collect and quantify the summer acoustic data using acoustic indices,and explores the relationship between the spatial-temporal variation characteristics of anthrophony and the landscape pattern of the parks.The results show that:1)The anthrophony in Fuzhou's urban parks in summer are mainly categorized into urban background sound,custodial sound and park sounds,which originate from the exterior,the interior and the visitor activities of the parks,respectively;2)The temporal heterogeneity of anthrophony is mainly driven by the activities of urban residents,showing a trend of low in the night and high in the day,while the spatial heterogeneity is influenced by park location,park facilities,node distribution,and the nature of patches;and 3)The park landscape pattern has a significant effect on the frequency and the duration of anthrophony.Custodial sound and traffic sound increase with the increase of gray space,while the increase of woodland area can improve the frequency and the duration of recreational sound;the NDSI index is negatively correlated with the landscape pattern index of the woodland and positively correlated with the index of the gray space.The findings indicate that woodland in the parks has a positive effect on anthrophony interference reduction.In this sense,the optimal strategy for improving anthrophony is proposed for the future urban parks,i.e.,increasing the area of buffer zone around parks and the vertical plants,making a rational plan for interior zones and roads in parks,and setting up certain anthrophony interventions in the areas with high anthrophonic disturbances.
