摘要：Authors present the fundamental contributions of Aldo A. Leopold (1887-1948), internationally renowned American conservationist, ecologist, scientist and scholar, exceptional teacher, philosopher, and gifted writer. He was one of the pioneers who devoted his life to thought about how farming should be productive but not interfere with natural systems. As the nation s first professor of game management appointed to the Department of Agricultural Economic in the University of Wisconsin, he devoted his activity to an idea about sustainable agricultural production. According to Leopold, the aim of sustainable agriculture is to preserve the integrity, stability and beauty of the biotic community. Leopold spent much of his time writing about agriculture and many of his philosophical statements seem to be the most meaningful today, and for his contributions he can stand sholder to sholder with Rudolf Steiner, the founder of anthroposophy, and Sir Albert Howard, founder of contemporary organic agriculture. Authors descibe the institutions which cherish the Leopold legacy. They especially present activities of the Aldo Leopold Center for Sustainable Agriculture, established at Iowa State University in 1987, and it represents one of the world leading institutions in sustainable agriculture techniques. The main purpose of the Center is to identify negative impacts of agriculture on natural resources and rural communities and contribute to development of profitable farming system that conserve natural resources. Leopold Center cooperates with Extention Service at Iowa State University and other groups in order to inform the public of new research findings. The Center is open to researchers from around the world who are interested in sustainable agriculture and specific projects and programs of the Center, ra and also coordinates some of them.
