Construction of the water conservancy engineering joint scheduling calculation scheme by artificial method is inefficient and prone to human error. In order to better generate the scheduling scheme, knowledge graph technology is explored to automatically generate the scheme. This paper studies two models of knowledge graph with regarding to the concept and physical one, and moreover indicates the storage, retrieval and inference of knowledge graph. Taking the Pi River basin as an example, the retrieval and inference method of the domain knowledge graph is applied, and the results, in the other words, the joint scheduling schemes, are stored as the specified data content and data format.Research shows that the domain knowledge graph is the information carrier of the water conservancy engineering joint scheduling calculation scheme, and the retrieval and inference of domain knowledge graph is the main method of automatic generation of water conservancy engineering joint scheduling calculation scheme. Compared with the traditional artificial method, it is more accurate and efficient.
