【摘要】：采用社交網(wǎng)絡(luò)數(shù)據(jù)對城市進(jìn)行感知與評價是一種新的城市感知定量研究方法。本文將新浪微博簽到數(shù)據(jù)作為城市感知的數(shù)據(jù)來源,通過文本挖掘和語義分析方法,探索用戶對重慶主城區(qū)城市風(fēng)貌的感知與評價。針對重慶主城區(qū)特色風(fēng)貌片區(qū),研究形成了簽到地圖、情緒地圖和對象地圖。簽到地圖客觀反映重慶主城區(qū)新浪微博用戶活躍程度的空間分布特征;情緒地圖挖掘活躍用戶對空間的情緒表達(dá)和正負(fù)面態(tài)度;對象地圖解析出現(xiàn)這種簽到熱力分布和情緒分布的原因,發(fā)現(xiàn)引發(fā)正負(fù)面態(tài)度的情緒對象。通過分析用戶對規(guī)劃師所設(shè)定的風(fēng)貌要素載體的典型意見,將要素載體歸納為有感知積極、有感知消極、無感知和有感知未設(shè)定4類。今后應(yīng)進(jìn)一步從要素識別和價值判斷兩個方面為規(guī)劃師塑造和管控城市風(fēng)貌提供參考意見。
