Abstract: On research of ecological ethics presently, anthropocentrism and non-anthropocentrism controvert actively about whether natural materials possess their ethical positions. The un-conciliation of their controversy and un-consent of their prspectives mean that the ecological ethics itself is undergoing a severe crisis of metaphysics. The basic reason of the crisis is that the controversy on human's value has led to the human's none-presence in the research of ecological ethics in a precondition without specifying‘what is human’. The metaphysical basis of the ecological ethics is not on whether the natural materials possess their ethical positions, but on the condition of ‘humans human’. Only if the human beings become the ones who protect the natural environment and possess the humanity of protecting the natural environment,can they protect the natural environment consciously.

Key words: ecological ethic, humanity, metaphysics
