%X Landscape ecological system is composed of ordered horizontal levels. The relationships of landscape structures and functions are distinct in different temporal and spatial scales, and it is useful to integrate hierarchy and components of landscape by regionalization concept. In this paper, the background and concept of the delineation of ecosystems were advanced. The principle of landscape heterogeneity on which the delineation is operated was also addressed. It was pointed out that the change from a framework based on a single natural indicator to another based on the integrated ecosystem approach reflects the progress in the understanding of human-nature reconciliation and the balance between biodiversity conversation and sustainable use of natural resources. On the basis of ecosystem integrity, a framework for the landscape ecological regionalization systems was recommitted, which followed the principles of hierarchy, multi-scale, origin-coherence, interdependence between landscape pattern and function, interaction among landscape functions and integrality of delineation units. Under these principles, the main scientific issues to be discussed were as follows: (1) the theory and system of comprehensive regionalization; (2) the changing processes, patterns and their interactions of the main elements in regional system; (3) the identification of the boundaries between the regional systems; and(4) the construction of the organizational levels of the system. Then, the differences and relationships among the landscape ecological regionalization and the natural regionalization, economical regionalization and the ecological regionalization were given. Finally, the paper assumed the application of landscape ecological regionalization theory in national, regional and watershed levels.
