This paper focuses the models and function of in the sign of urban land grading information system. After analyzing current system the paper discusses the structure of the system, functions of the system, data organization and data processing models etc. the system template, the relevant data structure and the empirical formulas of the affecting factor are proposed. The calculation methods of the service radius, general score and land grade automatically are presented. The urban land grading information system is designed. The system is implemented by Visual C++. The system illustrated by giving an example of the commercial land grading of the urban area of Wuhan City.
