摘要： 城市信息模型(CIM)可为城市规划、建设与管理运营过程提供多尺度三维数据底座和科学决策 支持，成为国家“十四五”规划建设内容。但 CIM 具有多尺度、多专业和多行业应用交叉融合的复杂特性， 不利于指导模型集成应用和信息高效共享，建立统一的 CIM 分级分类将有效改善这一问题。通过梳理综合对 比分析城市三维模型、CityGML 分级及建筑信息模型(BIM)等标准的分级层次，综合研究 CIM 概念及范围，提 出了 CIM 从地表模型到零件级模型逐渐精细的分级方法，并得到了初步验证。采用面状分类法在 BIM 分类的 基础上，对 CIM 分类进行定义与扩展，从成果、进程、资源、特性和应用 5 大维度探究了分类及规则。CIM 分级与分类研究，有助于明确和规范 CIM 特征，促进模型建立、加工、表达与共享应用。

Abstract: The research is aimed at key characteristics of City Information Model (CIM) on level and classification. CIM could provide multi-scale 3D data base and scientific decision support for city planning, construction, management and operation, which becomes a part of 14th five - year national economic and social development planning in China. CIM has the complex characteristics of multi-scale, multi-specialty and multi-industry cross-integration, which is difficult to guide the integrated application and sharing information of models. The establishment of a unified levels and classification of CIM will effectively improve the situation. By comparing and analyzing the existing standard systems of City three-dimensional model, CityGML classification and Building information model (BIM), comprehensive concept and levels of CIM are deeply explored. This paper proposed a gradually refined levels of CIM from 1st to 7th, which includes terrain surface model, frame model, standard model, fine model, functional level model, component-level model, and part-level model. The content, feature and precision of seven-level models were described and preliminarily verified. Based on BIM classification, this paper used faceted classification method to define and expand CIM classification., including the five dimensions of result, process, resource, character and application. This research explored the levels and classification characteristics of CIM, which contribute to the creation, procedure, display, sharing and application of CIM. 

Key words:  , city information model, levels of CIM, classification of CIM, building information model, geographic information system
