UrbanSim新进展及在中国应用的建议
首发时间:2015-11-04
摘要:由于大数据时代的出现,开展城市模型或城市研究成为了一种趋势。城市模型是在对城市系统进行抽象和概化的基础上,对城市空间现象与过程的抽象数学表达,是理解城市空间现象变化、对城市系统进行科学管理和规划的重要工具,可以为城市政策的执行及城市规划方案的制定和评估提供可行的技术支持。本文主要介绍了一种微观模拟的大尺度城市模拟系统UrbanSim。该系统不仅在分析单元和建模技术上都有很好的优势,还加入了大量数据方法,引入了经济学原理,其分析、处理问题的思想都有很多借鉴之处。本文主要介绍该模型设计思想的发展、模型组成、建模方法,并总结了模型的主要优势以及我国运用方面存在的问题,以便于为我国城市发展模拟研究提供借鉴。

UrbanSim's New Progress and Suggestions about its Application in China
Abstract:The appearance of the era of big data make urban model and urban studies become a trend.Urban model is an abstract mathematical expression of the process and the phenomenon of urban space on the basis of abstraction and generalization in urban system.It is also an important tool for understanding urban space change and scientific management and planning about urban system.And it can provide feasible technical support for urban policy execution and the formulation and evaluation of urban planning.This paper mainly introduces a urban mirco-simulation system of large scale-UrbanSim.The system not only takes advantage of unit and modeling technology, but includes large amounts of data methods and principles of economics,which are worth of learning.This paper mainly describes the model design, model composition, and key modeling methods, and summarizes the characteristics and advantages of this model. This review provides a reference for urban growth simulation research in China, which will be meaningful and helpful for promoting related research from another point of view.
