大地上的“异乡者”是徐则臣小说世界最为核心的文化表征和诗性空间，不仅回应着文学传统的古老乡愁，更具有代际身份的独特体验和书写景观，渗透着“70后”作家对当代中国现代性经验的情感体验。在他笔下“异乡者”们穿行在文本“出走-返归-出走”的叙事结构中，主要包括精神远离、异乡迷思、近乡情怯、渴求拯救等形象类型，并在“复仇”和“救赎”的两类主题内部呈现出边缘心理、思想孤独，又兼具情绪冲动、理想主义的复杂精神特征。基此，本文认为徐则臣小说创作对“异乡者”的偏爱，一方面源于作家真实的成长与教育经历，另一方面更源于改革开放时代“同代人”对当代社会感觉结构的深层回应，深植于作品“流浪”诗学、文化民族性和乌托邦理想的错位对话与互为认同的矛盾经验之中。

The "foreigners" on the earth is the most core cultural representation and poetic space in Xu Zechen's novel world. It not only responds to the ancient nostalgia of literary tradition, but also has the unique experience and writing landscape of intergenerational identity, and permeates the emotional experience of the "Post-70s" writers on the experience of Contemporary Chinese modernity. In his works, the "foreigners" walk through the narrative structure of the text "run away--return--run away", mainly including image types such as spiritual distance, foreign land myth, fear of being close to home, and longing for salvation. In the two themes of "Revenge" and "Redemption", they show the complex spiritual characteristics of marginal psychology, ideological loneliness, emotional impulse and idealism. Based on this, this paper believes that Xu Zechen's preference for "foreigners" in his novels, on the one hand, stems from the writer's real growth and educational experience, on the other hand, it also stems from the deep response of "contemporaries" to the contemporary social sensory structure in the era of reform and opening up, and is deeply rooted in the misplaced dialogue and mutually recognized contradictory experience of "wandering" poetics, cultural nationality and utopian ideal.
