Problems solved by technology
[0004] At present, watershed flood control planning is mainly based on the experience and knowledge of planners for data collection, collation, analysis, and scheme design. On the one hand, manual data collection is time-consuming and laborious, difficult to coordinate, and data integrity cannot be guaranteed; on the other hand, data analysis and utilization It is difficult to go deep, and it is difficult to give full play to the overall value of data assets through scattered data, and it is difficult to carry out effective analysis of data

Embodiment Construction
[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0031] like Figure 1-2 As shown, a method for constructing a knowledge map of watershed flood control planning data of the present invention includes the following steps:
[0032] 1) Sort out the data required for flood control planning in the basin; extract and organize the data items required for flood control planning, including natural conditions, hydrometeorology, Data on the status quo of economic and social, flood disaster, flood control and flood control engineering measures and non-engineering measures, economic and social development planning and related industry (department) planning, previous water conservancy planning and related analysis, research results, etc. Data items are filtered and labeled with type labels.
[0033] Among them, the natural condition data mainly includes: physical geography, topography, river systems, lakes...

The invention relates to a method for constructing a watershed flood control planning data knowledge map. The method constructs a watershed flood control planning data knowledge map based on space-time, topology, and hierarchical relationships, and uses spatial and statistical analysis methods to apply the flood control planning data knowledge map. This method can effectively improve the efficiency of watershed flood control planning data search and collation, as well as the collaborative ability of planning and design; it can improve the ability to analyze the relationship between flood control planning data in the watershed, as well as the application service ability of data; the construction of knowledge graph of watershed flood control planning data and The application makes full use of existing technologies and methods, and is fast and versatile. It can not only be applied to the field of flood control planning for watersheds, but also combined with knowledge in other fields, it can also be applied to hub design, joint watershed scheduling, construction, operation and maintenance, etc. It is worth applying promote.
Description
technical field [0001] The invention relates to the fields of river basin flood control planning and spatial analysis, in particular to a method for constructing a knowledge map of river basin flood control planning data. Background technique [0002] Knowledge Graph combines the theories and methods of applied mathematics, graphics, information visualization technology, information science and other disciplines with methods such as metrology citation analysis, co-occurrence analysis, etc. The core structure, development history, frontier fields, and overall knowledge structure are modern theories for the purpose of multidisciplinary integration. It displays the complex knowledge field through data mining, information processing, knowledge measurement and graph drawing, reveals the dynamic development law of the knowledge field, and provides practical and valuable reference for the subject research. [0003] Spatial analysis is a quantitative study of geospatial phenomena, ...
