摘要:城市信息模型（CIM）是我国智慧城市建设及城市数字化转型的重要抓手之一。其核心技术主要包括物联感知技术、GIS与新型测绘技术、孪生建模技术、可视化渲染技术、仿真推演技术和交互控制技术等。本文以独角兽岛智慧园区项目为例，探讨CIM技术、物联网技术、大数据技术及可视化渲染技术的交汇与融合应用，设计并建设应用场景支撑产业园区全生命周期的规划、建设、管理、运营以及园区空间价值提升，形成园区、产业、市场和社会的数字化运行理念和方式，并提炼出项目中展现出的特色与亮点，为推动我国智慧园区及智慧城市的建设提供基础支撑和建设经验。

Abstract: City information model (CIM) is one of the important tools for the construction of smart cities and the digital transformation of cities in China. Its core technologies mainly include IoT sensing technology, GIS and new surveying and mapping technology, digital twin modeling technology, visual rendering technology, simulation deduction technology, and interactive control technology. Taking the Unicorn Island Smart Park project as an example, this article explores the intersection and integration of CIM technology, IoT technology, big data technology, and visualization rendering technology; designs and builds application scenarios to support the entire lifecycle of industrial parks from planning, construction, management, and operation, to spatial value enhancement; forms digital operation concepts and approaches for parks, industries, markets, and society; and extracts the characteristics and highlights shown in the project to provide basic support and construction experience for promoting the construction of smart parks and smart cities in China.
