Naess, a famous philosopher in Norway, first proposed a new environmental philosophy: deep ecology, also known as "ecological wisdom"。 He put forward this term in his article "The Shallow and the Deep, Long-Range Ecology Movements: A Summary。" According to Naess, traditional approaches to life conservation and environmental protection are based on shallow ecology。 He deduces the deep ecology theory system of 4 level tower on the basis of summarizing and analyzing the theories of the deep ecology scholars to set internal logical relation of the theory of deep ecology。

This article will interpret the ecological view of Island of the Blue Dolphins based on the theory of the first layer which also was the theoretical basis of deep ecology。 The first level is based on the theory of Buddhism, Christianity, and the deep ecology of philosophy theory。 It shows the two highest standards of Deep Ecology -- the equality principle of ecological centralism and the self realization principle。 The center of the eco equality refers to all the beings in the biosphere as a whole。 They are closely linked and have equal chances of survival and development。 They also have the right to realize their intrinsic value。 The equality refers to the equality of all ecological centralism in the whole biosphere。 Self does not refer to one's own inpidual self, but refers to the "big" self that goes beyond the inpidual's emphasis on wholeness and relevance。 Self fulfillment refers to promoting the unique spirit of human to let oneself live and others alive。
