摘要

Environmental problems have been modeled and analyzed using GIS for long time, and they are often described by a set of interacting models from multiple disciplines. In this paper a composite process for environmental problem with multiple models is analyzed. A system dynamics modeling method, STELLA, is introduced to illustrate how to model the composite process with cause-effect relationships. Compared with other environmental modeling methods, environmental modeling supported by semantic geospatial Web service has the advantages of achieving interoperability and allowing realtime and online updating of the deployed models. A prototype system for Modeling Environmental Process using Semantic Geospatial Web Service, i.e. MEPSGWS, has been designed, which includes process ontology, rules for cause-effect relations, GML-based parameter type, Web service description language, and interoperable protocol. As an application of MEPSGWS, a watershed composite process is chosen to illustrate how to model a composite environmental process with semantic geospatial Web service.
