摘　　要：多分辨率建模是复杂大系统建模与仿真的关键技术之一,目前相关的研究主要采用了定性分析的方法。随着仿真技术的不断发展,这些定性分析方法已成为进一步研究的瓶颈,提出了定量分析模型分辨率的需求。在深入研究模型性质的基础上,建立了模型分辨率的定量描述概念,提出了一种具有方向性的基于描述的细节层次和详细程度的分辨率定量度量方法,并以一简化的气象模型为例说明了其应用。最后通过理论分析和推导,证明了该度量方法的合法性。Multi-Resolution Modeling （MRM） is one of key technologies in large-scale complex system simulation, and to date, related researches are based on qualitative analysis. With the development of simulation technology, the qualitative analysis method has become a bottleneck for further study, and quantitative analysis of model resolution is required. An approach to quantitative measure of model resolution was put forward, and directions were provided based on level of detail（LOD） and degree of detail （DOD）. The approach was based on further study and quantitative description of model resolution. The application of the method was illustrated by a simplified weather model. And finally, the validity of the method is proved by theoretic inference.
