Abstract: Jack London is one of the leading American realists in the late nineteenth and early twentieth century. Among his famous novels and stories, he is best known for his dog stories. White Fang is one of his famous novels. White Fang is about a wolf who is separated from his mother at puppyhood. And White Fang has different experience with his three different masters. My paper is to introduce eco-ethics and its theoretical basis and attempts to employ the theories of eco-ethics combined with literary criticism to reveal intrinsic value of nature and to examine the relationship between man and nature in White Fang. With the development of modern civilization and the deterioration of the environment, human beings begin to realize conflict between man and nature, man’s position in the whole ecosystem and the harmony between man and animals or even nature. London’s strong personal and literary identification with the animals and nature embodies his early ecological awareness. In the meanwhile, he also set a good example for modern people to deal with the relationship between man and nature correctly.
Key words：eco-ethics; White Fang; man and nature
摘要：杰克·伦敦是十九世纪末二十世纪初杰出的现实主义作家的代表。在他众多的小说和故事中，他的动物小说最为著名。《白牙》就是其中之一。《白牙》是一部关于幼时就与母亲分离的一只小狼与它不同的三个主人相处的故事。本文介绍了生态伦理学的观点和理论基础，并用生态伦理学的理论结合文学批评去分析《白牙》，力图展现作品中的自然的内在价值，并探讨人与自然的关系。随着现代文明的发展和环境的恶化，人类开始意识到人与自然之间的冲突、人类在生态系统中的地位以及人与动物甚至与整个自然的和谐问题。杰克·伦敦的强有力的启示和对动物与自然的文学刻画体现出作者早期的生态意识，同时也给予现代人正确处理人与自然的关系树立了榜样。
