Abstract：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.
