Research on ontology-based meta conceptual model of simulation system
基于本体的仿真系统元概念模型研究*

Present mathematical models for simulating the temperature field of mixted terrain surface often simplify the energy transfer process by omitting the interactive fluxes among terrain components, which trails off the accuracy of simulation results. This paper proposed a coupled model for soil-vegetation mixed terrain based on the analysis of the material components and the spatial distribution characteristics. By integration of the interactive radiation fluxes between material components, the energy balance for soil-vegetaion-atmosphere was expressed in the coupled model. Experiment results show that the temperature field distribution and infrared images obtained using the proposed model are more likely to correspond with reality, which justifies the effectiveness of the coupled model.
