EcoGothic,as the combination of Gothic and eco-criticism,is an attempt to re-shape people's concept of nature.Rooted in the idea of wilderness and developing from the eco-criticism's nonhuman turn,ecoGothic re-encodes the concept of romantic and green nature,highlighting its uncanny,violent and horrible aspects.On the basis of material eco-criticism,postcolonial eco-criticism and ecofeminism,it has developed into three theoretical sub-divisions:nonhuman ecoGothic,racial ecoGothic and feminine ecoGothic.Its view of nature,with the concept of"ecophobia"as its centerpiece,not only refreshes our understanding of Nature and human nature,but also is instrumental to analyzing Gothic literature or the Gothic elements in literature that might go against the grain of green eco-criticism.
