An irrigation engineering information management system based on B/ S model is introduced in this paper． This system includes information management and space display function． It has realized information query，statistical analysis，report generation，import and export，space display with the help of WEB software development techniques． It standardizes data format，code channels and other irrigation engineering items，clarifies the logical relationship of data before the development of database system． The idea of modular design is adopted to reduce the difficulty of development． To improve the user experience，the system uses simple interface framework． It can realize the data diversification display in the form of graphs，which can better meet the requirements of engineering information management and improve the management level．
