从符号域到生命符号学：塔尔图对符号界域的推展

摘要

符号域（semiosphere）作为文化符号学的重要理论，是塔尔图学派的领军人物尤里·洛特曼留给其继承者们的宝贵学术遗产。在新一代塔尔图符号学家的共同努力之下，符号域理论得以和塔尔图的另一宝贵学术资源---乌克斯库尔的环境界（Umwelt）理论相融合，从而形成了新塔尔图学派的理论基石。在此基础上，塔尔图的符号学者们将符号学研究推进至生命符号学的领域，从而极大地拓展了符号学的疆界，为当代的符号学发展做出了重要贡献。%Semiosphere,one important theory in the cultural semiotics,is the valuable heritage left by Juri Lotman,the leading figure of the Tartu School. With the efforts and collaborations of the new generation of semioticians of Tartu School,semiosphere has been merged with another precious theo-retical legacy,the theory of umwelt of Jakob von Uexküll,and forms the theoretical cornerstone of the new Tartu School. Based on this theory,the semioticians of Tartu School pushed the semiotic studies to the realm of biosemiotics,greatly expanded the boundary of semiotics,making significant contribu-tions to the development of current semiotics.
