Abstract: The basic principle of landscape eco-classification is discussed in this paper. Two-seriessystem of structural and functional classification is considered to be favorable to landscape eco-classification. In addition, bio-production, environmental service and cultural support are put forward as the basic functional types of landscape ecosystems. The study is expected to be beneficial to the development of emerging landscape ecology.
