本研究旨在探討奈及利亞小說家欽努阿．阿契貝處女作《大崩解》中的生態意識。時至今日，學術界對這本出版超過五十年的小說彰顯之生態議題幾乎未曾深入探討。對於一本以顯著篇幅描寫殖民前伊博部落的小說來說這著實令人費解，因為當時以農耕為主的伊博人和自然的互動更貼近而有彈性，也更能啟示我們的生態思維。為填補這個學術空白，遂設此研究議題。生態學者的理論支持外，本論文之研究方法還納入德希達的解構。這兩種理論看似牴觸，但本研究結果證明，兩者的合併應用不但未削減譯解效力，反使我們對這本小說有更精微全面的理解。

This study seeks to undertake an ecologically oriented criticism of Chinua Achebe’s first novel, ＂Things Fall Apart＂, that was published more than fifty years ago (1958). Up to the second decade of the 21st century, approach to the novel as such is surprisingly insufficient. Indeed, this could not be the case with an age in which the ecological awareness is gaining its ground. Nor could this neglect be the case with a literary work that devotes much space to the delineation of the pre-colonial Igbo society, an agrarian tribal community characteristic of its more spontaneous, more resilient interaction with the environment and nature. To fill the critical lacuna, therefore, the first section of this paper tries to identify the elements that both typify ＂Things Fall Apart＂ as a nature novel and characterize the Igbos as a people with an ecological mindset. On the other hand, as a writer who received a modern education, Achebe makes some revisions to the Igbo’s original understanding of nature. With theoretical help from some ecocritics and the deconstructionist Jacques Derrida, the second half of this paper will then evaluate the Igbo concept of nature in both ecocritical and deconstructionist terms. The results show that a combined application of ecocriticism and deconstruction can not only increase the validity of the related interpretations of the novel, but also produce more nuanced and comprehensive view of it.
