“城市引擎”规则建模可以快速生成大量的模型,在城市规划领域有很大的应用潜力,但目前国内外对其研究较少。本文从城市规划角度出发,在已有研究基础和实践案例上,对规则建模的优势、模型精细程度、建模步骤和如何辅助城市规划做了研究。在城市规划应用方面提出规则建模主要有数据准备与处理,城市建设要素类型分类,规则编写与赋予,模型生成和深化四个步骤。基于其建模精度,适宜应用的规划层次是总体规划、控制性详细规划。其在城市规划的辅助作用主要体现在三维模型空间展现、数据输出和分析、辅助规划管理和提供公共参与平台,以及与其他软件结合辅助规划方案设计和管理。
Urban engine s rules modeling can quickly generate a large number of models in the field of urban planning has great potential for applications, but less research at home and abroad. In this paper, from the perspective of city planning, based on the existing research foundation and practice cases, this paper studies the advantages of rule modeling, model refinement, modeling steps and how to assist urban planning. In urban planning and application of the proposed rule-based modeling are data preparation and processing, classification of urban construction elements, rule writing and giving, model generation and deepen the four steps. Based on its modeling accuracy, the appropriate level of planning for the overall planning, control of detailed planning. Its auxiliary role in urban planning mainly manifests in the space of three-dimensional model, data output and analysis, auxiliary planning management and public participation platform, as well as assisting the planning and design of the program with other softwares.
