城市公园声环境调查与评价——以长沙湘府文化公园为例

Survey and Evaluation on City Park Acoustic Environment: A Case Study of Xiangfu Culture Park in Changsha

选取长沙湘府文化公园作为研究对象,采用定点测量与问卷调查相结合的方法,对城市公园声环境进行评价。结果表明:(1)湘府文化公园中声景主要由自然声、生活声和人工声构成,游人对自然声满意度最高,生活声次之,人工声最低;(2)城市公园中声景观满意度与主观响度、好感度、协调度存在相关性,其中主观响度与满意度呈负相关,好感度、协调度与满意度呈正相关且相关性高于主观响度;(3)通过引入自然声源、优化空间格局、控制人工声源等能有效优化公园声环境。

In this study, Changsha Xiangfu Cultural Park was selected as the research object, and the acoustic environment of the urban park was evaluated by the method of fixed-point measurement and questionnaire survey. The results show that:(1) The acoustical landscape in Xiangfu Cultural Park is mainly composed of natural sound, living sound and artificial sound, and the tourists' satisfaction with natural sound is the highest, followed by living sound, and artificial sound is the lowest;(2) The satisfaction of acoustical landscape in urban parks is correlated with subjective loudness, good feeling and coordination, and the subjective loudness and fullness are the most important factors. There was a negative correlation between the degree of intention, and a positive correlation between the degree of favor, coordination and satisfaction was higher than the subjective loudness.(3) By introducing natural sound sources, optimizing spatial patterns, controlling artificial sound sources, the sound environment of the park can be effectively optimized.
