Lacking analytical and modelling functions is widely recognized as a major deficiency of currently available GIS. Model Base System being put forward in recent years is aimed at providing powerful functions such as model management and analysis. Model Base System can be utilized to classify and maintain various models, and support their generaltion, storage, query, management and analysis.;Current research on MBS is primarily focused on specific application fields, and such systems can only be used in their specific fields. When faced with other fields, those systems need large modifications or to be developed from scratch. An economical and flexible way is to develop a general platform of MBS which experts in various fields can use to build their own model bases efficiently. In this case, we designed and developed an Osprey Model Base System General Platform. Its architecture is put forward, and the schemes of some critical techniques of the platform such as model dictionary, data interface and model-creating techniques are presented in detail. Then the main functions of the platform are outlined.;In National High-Tech Project 863-07, we built MBS for Marine Fishery Services efficiently on the Osprey Model Base System General Platform. This success demonstrates that the idea of the MBS platform is feasible. An example of model analysis-Virtual Population Analysis is also presented.
