广州城市化梯度对公园声环境的影响

Effect of Urbanization Gradient on the Acoustic Environments of Parks in Guangzhou

对沿广州市不同城市化梯度分布的5个公园--越秀公园、天河公园、白云山风景区、帽峰山森林公园和石门国家森林公园的声环境动态进行监测,结果表明:1)整体上,随着城市化程度的增加,公园园区噪音的数值增加;2)公园园区内声环境受游客节律性生活的影响较大,噪音值随时间变化呈现出不同幅度的波动;3)整体上,广州市城市公园的噪音承载量尚未处于超负荷状态,并且沿城郊方向,公园的噪音承载潜力递增。因此,建议鼓励游客在选择公园游玩时更多考虑远离城市中心的公园。

This study monitors the dynamics of sound levels of Yuexiu Park,Tianhe Park,Baiyun Mountain Park,Maofeng Mountain Forest Park and Shimen National Forest Park located at different urbanization gradients in Guangzhou.The results show that the level of noise increases with the increase of urbanization generally.Secondly,human activities significantly impact the acoustic environment in parks and the level of noise fluctuates in different degrees over time.Finally,the noise carrying capacity of urban parks in Guangzhou is enough to bear existing noise pressure and parks near the suburb would have good potential to bear more noise pressure.Therefore,it is suggested that visitors could take more consider on the park near the suburb.
