摘　　要：针对基于山水林田湖草是生命共同体的系统思想,本文研究设计了一套基于混合建模的自然资源时空数据模型构建方法。该方法集成并扩展了实体表达、时空演变、地球空间网格、业务关系等多种模型,从而满足了自然资源在时间、空间、语义、管理、服务等方面一体化表达的需要。Mountains,rivers,forests as well as farmlands,lakes,grasslands and deserts all make indivisible parts of the ecosystem,they consist a community of life.Based on this concept,a set of construction method of spatial-temporal data model of natural resources based on hybrid modeling is studied and designed.This method integrates and extends various models such as entity expression,temporal and spatial evolution,geospatial grid and business relationship.This method can meet the needs of integrated expression of natural resources in time,space,semantics,management and service.

关 键 词：实体模型 时空模型 地球空间网格模型 业务关系模型
