Development of crop model base system based on Web

In order to suit the demand for both crop model development and application for information system, the structure for crop model base was analyzed. A software architecture for Web-based crop model base (WCMBS) was put forward, which includes crop model base (CMB), model base management system (MBMS) and system interface (SI). The system was developed with three-layer B/S architecture by using Asp.net+ XML, and the database was SQL Server2005. In order to achieve the transfer of the parameters in different models, the model description document based on XML was used to describe the model parameters. The system has the advantages of?easy to use,?Web-based and high?reusability.
