Abstract: An information system of land consolidation projects management (LCPM) based on the workflow model and business ontology is designed to solve the problem of that traditional information systems can′t handle the complicated data and business of land consolidation projects simultaneously. The business ontology is established on the basis of related official documents of management measures and expert knowledge, and it is regarded as the metamodel of the workflow model of LCPM which can make the integration of workflow and dataflow, and satisfy the uncertainty of business of LCPM. Functional modules of the system with weak coupling and strong polymerization are designed in accordance with the workflow model of LCPM, and the software development pattern of plug-in framework is adopted to realize the system on computer. At last, taking the Guangxi Zhuang Autonomous Region as a case study, we find that the design of Information system of LCPM presented above is effective and feasible.
