| 城市森林公园是重要的城市生态与社会功能空间。
声景感知作为游憩体验的重要因素，掌握其时空特征对声景规
划及管理具有重要意义。以福州国家森林公园为例，基于现场
监测与公众调查数据，利用声景地图从时空维度分析森林公园
声景的动态特征，并通过空间自相关模型检验声景感知属性的
空间依赖性，以及探讨物理声学指标与声景感知属性之间在
不同时段的动态空间关系。结果表明，物理声学指标(L Aeq、
L 10、L 90、L 10-L 90)与声源和谐度在时空尺度上均存在不同程
度的动态变化与空间差异；声源和谐度在全局和局部模型中都
出现了空间自相关，并随时间变化呈现不同特征；各物理声学
指标对声源和谐度的空间分布在不同时段具有潜在负面影响。 |

| Abstract: |
| Urban forest parks are important urban ecological and
social function spaces. As an important element of the recreational
experience, it is important to understand the spatio-temporal
characteristics of the soundscape for its planning and management.
This study takes Fuzhou National Forest Park as an example, and
analyzes the dynamic characteristics of forest park soundscape in
spatio-temporal dimensions through soundscape maps based on
on-site monitoring and public survey data. Spatial autocorrelation
model was used to examine the spatial dependency of soundscape
perceptual attributes, as well as exploring the dynamic spatial
relationship between physical acoustical indicators and soundscape
perceptual attributes at different time periods. The results show that
the acoustical parameters of the soundscape (LAeq, L10, L90, L10-L90)
and sound harmonious degree vary dynamically and spatially
in different degrees in the spatio-temporal dimensions. Sound
harmonious degree is observed to be spatially autocorrelated in
both global and local models, and shows different characteristics
at different time period. The acoustic parameters could negatively
affect spatial distribution of harmonious degree of the sound
sources. |
