乐山城区社区“宁静指数”构建及宁静地图绘制

Construction of “Tranquility Index” and Tranquility Mapping in Leshan Urban Community

摘要: 研究了城市噪声问题及其对居民生活的影响。随着城市化发展，城市声环境逐步恶化，噪声问题日益严重。为解决此问题，选取乐山市中心城区作为研究区域，运用宁静评级预测工具(TRAPT)和“宁静感知理论”，从区域混合度和物理噪声两个视角建立分析框架，并引入了“宁静指数”指标。通过分析噪声投诉的时空分布特征及其与POI功能兴趣点数据的关系，构建了“宁静指数”模型并绘制宁静地图，为城市声环境管理和规划提供技术支持。

Abstract: This study examines the urban noise issue and its impact on residents’ lives. As urbanization progresses, the urban sound environment deteriorates, and noise pollution becomes increasingly severe. To address this issue, this paper selects the Leshan urban area to study, employing the Tranquillity Rating Prediction Tool (TRAPT) and the “Perceived Tranquillity Theory” to establish an analytical framework from the perspectives of regional mix and physical noise, and introduces the “Tranquility Index” indicator. By analyzing the spatial-temporal distribution characteristics of noise complaints and their relationship with POI data, this paper verifies the correctness of the “Tranquility Index” model, providing technical support for urban sound environment management and urban planning.
