在重庆市主城区选取了具有典型山地形态和丰富声景的碧津公园为研究对象,采用声漫步方法对该山地公园的声景和视觉景观进行调查评价。结果表明,碧津公园的声景组成可分为人工声(65%)和自然声(35%)两大类;人们更偏爱流水声、鸟叫声等自然声;公园平均声压级为62.7d BA,远超过相关标准的限值;声景的舒适程度与声景类型、空间的围合程度都存在显著相关性;“近的—远的”、“单一的—复杂的”、“柔和的—刺耳的”、“无方向的—有方向的”等词组是描述山地公园声景最贴切的形容词。
In the main urban area of Chongqing, Biking Park, with its typical mountainous morphology and rich soundscape, was selected as the research object. The sounding and sighting landscapes of this mountain park were investigated and evaluated by the method of sounding and walking. The results show that the composition of soundscape in Bijin Park can be divided into two categories: artificial sound (65%) and natural sound (35%); people prefer natural sound such as running water and bird sounds; the average SPL of the park is 62.7 dBA, far exceeding the limits of the relevant standards; the degree of comfort of soundscape is significantly correlated with the type of soundscape and the degree of enclosure of the space; “near-far”, “single-complex” “,” Soft-jagged “,” non-directional-directed "are the most appropriate adjectives describing the soundscape of a mountain park.
