Eco-hydrological ontology in inland river basin:Construction method and application
Wang Wei-hu · Journal of Glaciology and Geocryology · 2014
Large-scale( 10 × 104km2) watershed modeling is facing many challenges at present. There are bottlenecks in the understanding and mathematical expression of the process,the scale transformation and the coupling mechanism of eco-hydrological processes. The modeling method based on ontology may spli the existing model into components according to multistage process represented by ontology. Then it is able to add component and to get custom model based on demand. Through semantic recombination and technological innovation,a new method is provided for large-scale river model integration. In this paper,the eco-hydrology in the Heihe River basin is taken as an example. After explaining the connotation of eco-hydrological ontology and analyzing the existing ontology building methods,the eco-hydrological ontology construction method is put forward based on knowledge,which is proved to be effective and feasible through constructing an ontology of desert ecosystem.
