Macroscopic ecology deals with problems of large spatial and temporal scales at the ecosystem level,which emphasizes on the development and effects of spatial heterogeneity,interactions and influences of spatial patterns on ecological processes, the hierarchical structure of landscape, the importance of spatial and temporal scale and ecological effects of human.

According to the analysis of topographic characters,climate types,the change trend of both temperature and precipitation,use of the technique of RS and GIS,the spatial distribution pattern of macro-scale ecological background were discussed.
