On maintaining ecological balance and promoting economical development, it is necessary to strengthen the spatial relation among the landscape patterns of similar function. The growing awareness of the adverse effects of habitat fragmentation on natural systems has resulted in a rapidly increasing number of actions to reduce current fragmentation of natural systems as well as a growing demand for tools to predict and evaluate the effect of changes in the landscape on connectivity in the natural world.   Landscape ecological system is composed of ordered horizontal levels. The relationships of landscape structure and functions are distinct in different temporal and spatial scales, and it is useful to integrate hierarchy and components of landscape by network concept. Landscape is a spatial structure that is formed by contact corridors and patches, and the flow and interaction of energy, material, and species of landscape must depend on landscape network structure. In order to contact different horizontal levels and structure of landscape, the paper constructed landscape functional network, and divided landscape functional network into ecological functional network and urban functional network based on human survival and development needs, then illuminated framework, functions, and relationship of landscape functional network. We hoped to lay foundation of the theory and application for functional and structural adjusting and for landscape functional system construction.

Key words: landscape functions, landscape network, landscape pattern
