摘　　要：针对遥感信息模型的自动化模拟和计算中现有方法的不足,基于按需服务模式提出了面向空间信息应用需求的遥感信息模型模拟和描述方法,将遥感信息模型模拟计算过程分解为包含五个通用步骤的信息处理流程,采用语义关联方法来表达各阶段资源选取与应用需求间的对应关系,并给出相应的面向应用需求的遥感信息模型模拟的层次化转化和映射方法,最后通过典型应用案例展示了该方法的工作过程。A more available way of remote information model simulation and description was proposed and a novel method based on service on demand mode was proposed, and the semantic relationship description of information processing procedure gave the basic knowledge of resource selection and matching based on application demands. A hierarchical mapping and description method of remote information model was provided to realize the transformation from abstract model to concrete service chain, and a case study shows the work procedure of this method.
