LUTI模型原理、实现及应用综述

经济全球化背景下可持续发展已成为当今世界发展的主题。快速城镇化下的中国,城市空间的可持续性发展提上日程。为此,期待有力的、可操作的工具用于定量模拟城市空间演化过程、预测不同政策下城市空间的发展趋势,为城市化持续健康发展提供决策支持。本文分析了LUTI模型的基本原理、构建思路、实现框架和建立中国城市LUTI模型面临的问题,并回顾了国内外利用LUTI模型模拟城市空间演化过程,以辅助表明城市空间决策的研究现状,希望能为中国的城市空间可持续发展模拟分析研究提供参考。

THEORY,IMPLEMENTATION AND APPLICATIOINS OF LUTI MODEL

Sustainable development has now been becoming a main topic against the background of economy globalization. Meanwhile, China is enduring fast urbanization, so it is meaningful for China to ensure the sustainability of urban space development. As a result, an operational, powerful modeling tool is crucial to model the urban spatial evolution, forecast the trend of the urban spatial development under different urban spatial policies. Land-use/transport interaction mode (LUTI) is regarded as an important tool to help realize urban sustainable development analysis with the function to model the process of urban spatial development.Our object is to review the theory, evolution, classification of LUTI, discuss its implementation and applications, to provide a reference to establish LUTI models for Chinese cities. We analyzed the principle and characteristics of the LUTI model, reviewed its research status of modeling urban space evolution for sustainability evaluation, discussed the rules to develop a LUTI model and the problems encountered to build LUTI model for China's cities. The core theory of most LUTI models is still based on the Lowry's model theory.According to Lowry Model, urban development process is that of the interaction between urban land-use and transport. Urban industries could be classified into two classifications:basic sector and service sector. Basic sectors provide production sold to outside the city to make income for the city. Basic sectors are the base of the city to exist. The service sectors provide services for the city to run. The location of basic sectors determines the resident location of its workers and the resident location determines the location of service sectors.Lowry Model laid the base for the subsequent LUTI research.
