| 北京地区冬季气候寒冷干燥，植被郁闭度降低，地球物理声增加，生物声减少。为探测北京冬季声景变
化基本特征，根据地图 “十字型”筛选 10 个城市公园，记录分析绿地内冬季声景的构成情况和昼夜变化规律。
结果表明：城市公园冬季声景中人工声较多，生物声明显著少于其他季节，而且人工声昼间少于夜间，生物声
昼间多于夜间；在公园人工声源分类中，机械电子声最多，其次是话语声，活动声最少；冬季人工声峰值普遍存
在于清晨6:00–7:00时，在昼间的波动变化明显，于夜间趋于稳定，生物声峰值出现在上午8:00–9:00时，谷值出
现在凌晨3:00时左右；人工声与公园面积、公园年龄和时刻变化未见显著相关性，生物声与公园面积呈显著负
相关。实验发现城市公园冬季声景呈现出与其他季节声景的显著不同，生物的节律性变化导致冬季声景产生
了较为显著的变化。 |
| 英文摘要: |
| The winter soundscape was discovered to be notably different from other seasons in the trials. The cold and dry winter climate in the Beijing area leads to a decrease in vegetation depression. Geophony increases and biophony decreases in winter, and the rhythmic changes of organisms lead to more significant changes in the winter soundscape. To detect the characteristics of winter soundscape changes in Beijing, 10 city parks were selected to analyze the composition and diurnal changes of winter soundscape. The results reveal that: (1)There are more anthrophony in the winter soundscape of urban parks, and the biological statements are significantly less than in other seasons, and the anthrophony are less in the daytime than in the nighttime, and the biophony are more in the daytime than in the nighttime; (2) According to the classification of anthrophony sources, mechanical and electronic sounds are the most frequent in winter, followed by speech sounds and the least activity sounds; (3) The peak of anthrophony in winter generally exists in the early morning at 6:00-7:00 am, and the fluctuation changes significantly in the daytime and in the nighttime stabilization. The peak biophony occurred at 8:00-9:00 a.m., and the trough occurred around 3:00 a.m.; (4) No significant correlation was found between anthrophony and park area, park age and momentary change, and biophony was significantly negatively correlated with park area. |
