三维空间信息技术在城市国土空间规划中的应用研究

摘要

城市空间开发已由平面扩张转向地上、地表与地下立体利用，二维图件难以完整表达复杂空间关系。 本文采用文献归纳、技术流程分析和案例比较方法，构建“多源感知—三维建模—空间分析—情景模拟—实 施反馈”的应用框架，分析三维空间信息技术在现状调查、规划编制、方案比选、用途管制和动态监管中的 作用。研究认为，该技术能够提高规划的精细度、可验证性与协同性，但仍面临数据标准不统一、模型更新 成本高和业务融合不足等问题。应建设多尺度语义化空间底座，完善增量更新和模型验证机制，推动三维平 台由成果展示工具转向规划全周期决策基础设施。

Abstract

 Urban spatial development has shifted from planar expansion to the three-dimensional utilization of aboveground, surface, and underground spaces, while two-dimensional drawings can hardly fully express complex spatial relationships. Using literature review, technical process analysis, and case comparison, this paper constructs an application framework of “multi-source perception–three-dimensional modeling–spatial analysis–scenario simulation implementation feedback,” and analyzes the role of three-dimensional spatial information technology in current situation investigation, planning compilation, scheme comparison, use regulation, and dynamic supervision. The study suggests that this technology can improve the refinement, verifiability, and coordination of planning, but still faces problems such as inconsistent data standards, high model updating costs, and insufficient business integration. Therefore, a multi-scale semantic spatial foundation should be built, incremental updating and model verification mechanisms should be improved, and three-dimensional platforms should be promoted from result display tools to decision-making infrastructure for the whole planning cycle.
