摘要:

【目的】探讨南京市都市区声景观在城乡梯度变化下的空间特征,为声景观综合利用与科学规划提供参考。【方法】以南京市都市区为研究范围,对其进行城乡梯度的量化并设置研究样带,通过客观声级的测量,利用GIS软件对不同梯度下声景观进行分析评价。【结果】研究范围内声景观呈现明显的都市中心-城乡过渡带-乡村的城乡梯度分异与南北空间分异。声级以新街口为圆心向四周降低,呈先缓慢下降、后快速下降、最后趋于平缓的趋势,从市中心向东声级降幅最大而向西南方向最小。【结论】在城乡梯度视角下对声景观特征及演变分析可为研究区域声景观演变机制及空间规划设计提供参考。

Abstract:

【Objective】 In order to provide references for the comprehensive utilization and scientific planning of soundscape, we discuss the spatial characteristics of soundscape in Nanjing Metropolitan area under the gradient change of urban and rural areas. 【Method】 Firstly, we take Nanjing Metropolitan area as the research scope, quantify the urban-rural gradient and set the research transect. Secondly, after the objective sound level measurement, GIS is used to analyze and evaluate the soundscape under different gradients. 【Result】 The soundscape within the research scope showed the obvious urban-rural gradient differentiation and north-south spatial differentiation of the urban center, the urban-rural transition zone and countryside. The sound level decreased from Xinjiekou as the center of the circle, first slowly, then rapidly, and finally flattens out. Moreover, the drop in sound levels is the greatest eastwards from the city center and the smallest southwesterly. 【Conclusion】 The analysis of the characteristics and evolution of soundscape from the perspective of the urban and rural gradient could provide references for the study of the evolution mechanisms of the regional soundscape and the spatial planning and design.
