Abstract: Modern management of using water is one measure to improve the efficiency of agriculture irrigation. It’s difficulty to manage irrigation region by hand and use GIS to manage irrigation is an important way to improve the efficiency of irrigation. GIS has strong function of spatial database management and it could easily analysis geography data. According to the researching accomplishment on the irrigation management and the analysis of the process of the irrigation, the author preliminarily attempts to design the form of information system of irrigation in order to provide data to irrigation region management in the future. By the practice of development the Information Management System of Fengjiashan irrigation of shaanxi province, the author expounds the process of realization the key technology for the development information system of irrigation with MapX model as follow:(1)With the function of visual and exchanging data by Internet, where visual program tools, database, GIS model, and Internet are introduced. (2)The author especially introduces the MapX model and the method of set up spatial database and internet. (3)At last, the author put forward some helpful discussion on this field.
