本文在烏克斯庫爾的「主體世界」理論之上，融合了生態符號學的一個基本概念，即卡萊維．庫爾所提出的「多重自然」通過對烏氏的「功能圈」模式圖進行改寫，建立了生態符號學的一個新模式，旨在對人類文化如何模塑自然做出新的解釋。本文認為，語言作為文化主體世界的邊界，它在文化對自然進行映現時，起到了模塑的作用，這一看法是對塔爾圖一莫斯科學派觀點的繼承。在此基礎上，本文試圖指出，由於「功能圈」模式的重複性和循環性，這一新的模式可以為庫爾「多重自然」理論中的「零度自然」這一概念本身的不足提供一定的修正，也可以用來描述語言所產生的、原本不存在的自然對象在文化中的意義生成過程。

The concept of Umwelt raised by Jakob von Uexküll is the theoretic foundation of ecosemiotics, which deals with the sign-filtered and mediated relationship between human and nature. Language, as the boundary of cultures, according to T.A. Sebeok, is the secondary modeling system for the Umwelt of human beings, and shapes the world of meaning. Such a perspective is a further development of the theory of Tartu-Moscow School of Semiotics who takes language as the primary modeling system of cultures. This paper aims to propose a new ecosemiotic model, an integration of the model of ＂functional cycle＂ as well as the idea of ＂Multiple Natures＂ by Kalevi Kull, and explains how nature(s) are mapped and built by culture. Due to the repeatability and circularity of functional cycle, this new model supplements the idea of ＂Multiple Natures＂, and is capable of describing a meaning-generating mechanism. In this process, an object that does not originally exist in nature is created and represented.
