The integration and blending of the natural characteristics, social characteristics and ecological characteristics of land resources determine that land information management is a complex and comprehensive systematic project. However, land information management in our country has long relied on handwork, which is tedious and slow and inefficient. In order to improve the ability of land management department on land management, it is necessary to develop a land management information system with decision support function. Therefore, this paper will research and develop land suitability evaluation system based on Arc Engine. First, the choice of participating factors and the division of the system according to the system requirements and related experience, as well as references,
