【摘要】：采用社交网络数据对城市进行感知与评价是一种新的城市感知定量研究方法。本文将新浪微博签到数据作为城市感知的数据来源,通过文本挖掘和语义分析方法,探索用户对重庆主城区城市风貌的感知与评价。针对重庆主城区特色风貌片区,研究形成了签到地图、情绪地图和对象地图。签到地图客观反映重庆主城区新浪微博用户活跃程度的空间分布特征;情绪地图挖掘活跃用户对空间的情绪表达和正负面态度;对象地图解析出现这种签到热力分布和情绪分布的原因,发现引发正负面态度的情绪对象。通过分析用户对规划师所设定的风貌要素载体的典型意见,将要素载体归纳为有感知积极、有感知消极、无感知和有感知未设定4类。今后应进一步从要素识别和价值判断两个方面为规划师塑造和管控城市风貌提供参考意见。
