This article abstractly analyzed the characteristics of space, time and attribute in land environment from the aspects of resource, environment, economy and society. Based on the characteristics of 3D continuous space in land environment and token air-earth-life mode as the framework, the temporal logic relationship of objectified elements of air-earth-life in land environment was studied by the methods of object-oriented information abstract. The spatial and temporal characteristics of level, speed, strength and shape in the land environmental evolution were explored based on the mode of air-earth-life by combining the improving dynamic degree computing of air-earth-life in land environment and space-time overlay analysis method of GIS. This article achieves the function of air-earth-life factor analysis on the temporal evolution of the land environment and provides new ideas for scientific management and decision of temporal data in the regional land environment.
