To understand and solve various natural environmental problems, geoscience research activities are becoming increasingly dependent on the integration of knowledge, data, and models from scientists at different institutes and with multiple perspectives. However, the facilitation of these integrations remains a challenge because such scientific activities require gathering numerous geoscience researchers to provide data, knowledge, models, and tools from different institutes and geographically distributed locations. The pivotal issue that needs to be addressed is the identification of a method to effectively combine geoscience models in a distributed environment to promote cooperation. To address this issue, in this paper, a scheme for building a distributed geoscience model integration based on the open geospatial webservice specifications is proposed. The architecture of the geoscience model integration, model service management mechanism, XML description method for model integration, and integrated model execution strategy are designed and implemented. The experiment implements the integration of geoscience models in a distributed cloud environment and evaluates the feasibility and efficiency of the integrated geoscience model. The proposed method provides a theoretical basis and practical guidance for promoting the integration of distributed geoscience models; this approach can help to aggregate the distributed geoscience capabilities to address natural challenges.
