| 摘 要： | 结合土地环境演变的空间、时间和属性特征,以"天—地—生"要素框架为研究模式,进行土地环境影响要素时空数据组织方法研究。基于"天—地—生"模式的土地环境要素时空数据模型表达了土地环境天、地、生要素的时空逻辑关系,反映了影响土地环境演变的多维要素之间的多层次关联关系,并能减少数据访问的复杂度,又确保地理实体对象中影响要素间的有机耦合作用。

| Abstract: | Combining space , time and attribute features in land environmental change , with elements of ＂air-earth-life＂framework for the study of pattern , this paper research the organizational methods of temporal data of elements in land environment .Model of tem-poral data of elements in land environmental based on ＂air-earth-life＂framework expresses the temporal logic of elements of ＂air-earth-life＂in land environment , reflects the multi-level relationship among the multi -dimensional elements in land environmental change, meanwhile, it can reduce the complexity of the data accessing , also ensure the organic coupling effects of impact factors in ge-ographic entity objects . |
