Abstract: Landscape ecological classification (LEC), through establishing hierarchical classification system, can comprehensively reflect the spatial heterogeneties and their associations of definite regional landscape, and reveal its spatial structural characteristics and ecological functions, being the basis of landscape evaluation, landscape planning, and landscape management. In this paper, the concept of LEC was paraphrased, and the research progress of LEC was reviewed and analyzed from the aspects of framing classification systems, selecting indices, improving classification methods, mapping landscape ecotypes, and applications. The problems of LEC research and its development trend were pointed out.
