城市公园声景特性解析

采用实地勘测调研与现场问卷调查相结合的方法,对重庆市北碚公园声景构成及其时间变化、空间分布和声景的好感度与协调度进行调查研究.结果表明,城市公园声景由人工与自然声景构成,其中人工声景占主体;声音种类和强度的时间变化均与城市居民的生活节奏、公园游客数量等密切相关,一般上午10:00,公园内的声音以自然声为主,10:OO后,人工声逐渐增多,下午公园的声景特点与上午相似,公园声景的年变化差异主要体现在自然声,其他声音的年变化差异不明显;公园声景的协调度排序与好感度排序基本相同,好感度高的声景,其协调度往往也较高.

Analysis of Soundscape in Urban Park

Using methods of site investigation and questionnaire form from local people, the construdion, time-changes, spatial dislribution, favorable impression and coordination of soundscape in Chongqing Beibei park are sludied in this paper. The results show thal the urban park soundscope comprises both the artificial and natural soundscape, with the arlificial one in the main; thal the time-changing sound species and intensity have closely relation to the life pace of the urban residents and the number of visitors---normally, before 10:00 am, the main sound in the park is natural, and after that, the artificial sounds are increasing gradually. Moreover, the charaderistic of the soundscape in the afternoon is similar with that in the morning. Furthermore, the research also shows that annual change of the soundscape in the park is mainly reflected in the natural sounds, while the annual change of other sounds is unobvious; that the sequence of coordination is basically the same as that of favorable impression--the better the favorable impression is, the higher the coordination is.
