There are Anthropocentrism and Ecologism, two basic opposite viewpoints in environmental law, Anthropocentrism takes the protecting of the basic interest of human beings as the center and holds that ecological benefit can only be regarded as the object of laws, thus, inhuman entities, such as animal, plant and the nature, can not be the subject of legal relationship and can not be protected by laws．However，Ecologism believes that human beings, animal, plant and all ecologic system have their intrinsic value, should have equal subject position in laws and should be equally protected. These two opposite viewpoints have sharply different influence on the results of the cases．When environment law does not determine whether Anthropocentrism or Ecologism is basic stand, we can solve the opposition between Anthropocentrism and Ecologism by legal method of environmental law, especially the method of balancing of interest of the two．
