Since 1970s, because of global ecological crisis increasing, the relationship between human and nature had to be reflected. In the process of reflection, the Leopold's Land Ethic Thought, unacceptable in the past, has been re-examined and accepted gradually. Leopold's Land Ethic proposed to solve the environmental crisis with the whole concept of ecological methodology, based on the concept of non-anthropocentrism. Therefore, analyzing the root of land ethic thought and its main characteristics through the investigation of the formation process of land ethics, and through analysis of his thought to assess its effect, the article completes the research of Leopold Land Ethic Thought.With respect to the research into Leopold's Land Ethic Thought, the main contents includes the production of land ethic thought, the main ideas, the analysis and effects of land ethic thought.The first chapter researches into the production of Leopold Land Ethic Thought. By analyzing the economic and social background, scientific background and theoretical background, and personal background, the fact is verified that the production of Leopold Land Ethic is the combination of outside social factors and underlying individual factors. About the external factors of the production of Leopold Land Ethic Thought, what the society provides is the realistic ecological crisis, what the science provides is many kinds of ideas of, what the rationale provides is many kinds of value orientations. About the intrinsic factors, Leopold promote to ecological crisis's ponder, conformity ecological thought, establish the standard of Land Ethic, by his life. It can be said that Leopold establish Leopold Land Ethic Thought base on triggering and supporting of this condition.The second chapter cards and analyses the main thought of land ethic. Leopold gradually completed the main contents of the Land Ethic through the expanding morality, proposing the concept of community and establishing the community's obligations and new ethics scale. Leopold extended the scope of moral concern to the land, combined with the theory of evolution and ecology, changing the traditional human-centered economic pattern, establishing the ethical scale of "harmony, stability and beauty" to judge the behaviors. Thus humans are transferred from governors to the average one, which not only change the previous financial measure, also stressed the intrinsic value of nature. Therefore, land ethics both go beyond the traditional concept of natural economy, expanding the boundaries of ethics, and develop the overall ecology. On this basis, I believe that land ethics has the characteristics of"age confrontation","concept integration"and"boundary expansion".The third chapter demonstrates the plausibility of Leopold's land ethic thought, discriminating its being challenged and defended, exploring the reason for its influence effect. On the basis of combination with ecology ideas, the rationality of land ethics thought is proved from the multi-angle analysis of the eco-systematical integrity, the natural diversity and mutual dependence. Carding the defense and challenge, its being refused and accepted are analyzed. Like other new ideas, Land Ethics are being questioned, affirmed and accepted, without conclusion, but positively impact on the theory of ecological and environmental protection. Likewise, Leopold's land ethic has a positive impact on the development of china's environmental protection and ecological awareness of the people.Through studying the essence of Leopold's land ethic, the article aims at indicating that with the social background of current rapid economic development, harmonious society creation, we should pay attention to following the laws of ecology and rational utilization of nature to promote the creation of ecological civilization.
