摘　　要：从资源、环境、经济、社会等方面分析了土地环境的空间、时间和属性特征,依据土地环境立体连续三维空间的特性,以"天–地–生"模式为研究框架,通过面向对象信息抽象方法,进行对象化土地环境天地生要素的时空逻辑关系和模型构建方法研究。在此基础上,结合改进的土地环境天地生要素动态度运算和GIS时空叠置分析方法,探索基于"天–地–生"模式的土地环境演变的等级、速度、强度和形态等时空特征,实现了土地环境时空演变过程中天地生要素分析功能,为区域土地环境时空数据的科学管理和决策提供新思路。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.
