Abstract: The establishment and development of ecologtcal ethics are briefly described both inwestern country and in China．The relationship between ecological ethics and green economies as well as its different developing stages are discussed．Ecological ethics supports not only an extension beyond current individuals to cover the rights and interests of current generations (intragenerational equity criterion)，but also beyond future generations(intergenerational equity criterion)of humans．But deep ecology goes much further and opens up the moral referenee class to cover the rights and interests of non-human nature(animals,plants，species and ecosystem)．
