英文摘要： Massive amounts of information sources and domain knowledge pertaining to river basin can't be rapidly accessed and effectively applied in current water environment regulation applications due to various heterogeneity problems among multi-data recourses and the diversity of the knowledge representation. To meet this challenge, this research aims to propose the methodologies for automatic construction and adaptive organization of water environmental ontologies under the framework of digital river basin.This goal will be achieved by systematically and innovatively applying all kinds of methodologies and technologies in the realm of ontology, intelligent data mining and optimization. The mechanism for data-driven ontology learning will be proposed and the ontology learning approaches towards different heterogeneous data sources will be implemented by the integrated application and optimized regrouping of various ontology learning algorithms, thereby improving the coverage rate, consistence and accessibility of water environmental ontologies. The water environmental ontologies will be build up to accurately represent the characteristics of water environment system at multiple levels such as structure, semantics and knowledge. The improved and highly flexible ontology organization methodologies will be proposed i
