中文摘要：

福柯提出的“异质空间”理论将研究视角聚焦于都市空间的差异性，从这一角度出发重新审视鲁迅的杂文写作，会发现鲁迅在杂文中忠实记录了二三十年代中国城市空间的异化与杂糅。这种异质空间在鲁迅杂文中主要以“咖啡厅”“跳舞场”和“租界”“华界”等为代表，形成了异质空间的位移、杂糅和越界，体现了鲁迅杂文的反讽和悖论式的话语特征。鲁迅的异质空间的体验不仅仅具体标志了鲁迅文学活动的空间地域，同时也体现了鲁迅的文化立场，进一步表现出基于这种文化身份的话语形式，在写作中通过思想越界形成“反思性”叙事和现代性的话语特征，实现空间转向视角下鲁迅杂文的新的文学性生成。

英文摘要：

Foucault＇s ＂heterogeneous space＂ theory focuses on the urban space difference, from which one will find, if rexamining Lu Xun＇s essays, that his essays records faithfully the alienation and hybridity of China＇ s city space in the 1920s and 1930s. This kind of heterogeneous space is mainly represented by ＂cafe＂, ＂dance hall＂, ＂leased territory＂ and ＂Chinese settlement＂ in the form of displacement, mixture and cross-border of the heterogeneous space, which reflects his discourse features of irony and paradox. Lu Xun＇s heterogeneous space experience is not only a specific symbol of the geographical space of Lu Xun＇s literary activities, but also reflects Lu Xun＇s cultural position. It further shows the discourse based on this cultural identity, which generates Lu Xun＇ s new literariness from the perspective of space turn by the formation of ＂reflective＂ narrative and modem discourse characteristics by means of cross-border thought in his essays.
