In recent years, themes about ecology and nature have gained much attention from scholars and critics at home and abroad. These themes can also be reflected in Jean Rhys's Wide Sargasso Sea. To reveal the theme of ecology and nature in this novel, this thesis manages to explore the differing views Antoinette and Rochester hold and make a comparison between their eco?logical views by analyzing the way they treat animals and their standpoints about the relationship between human and nature in the light of Ecolinguistics. It finds out that Antoinette's positive and harmonious ecological view is incompatible with Rochester's neg?ative and indifferent one. This thesis hopes to provide a new perspective for studying this novel and to dig out the ecological mean?ing of it.
