specific Embodiment

[0029] When constructing the Yellow River water and sediment change data warehouse, it is necessary to consider what type of data needs to be stored in the data warehouse, the relationship between various types of data, how to automatically and quickly release data resources, and how to provide people with quick browsing and analysis. In view of these aspects, when constructing the Yellow River water and sediment change data warehouse, preparations can be made from the following aspects:

[0030] (1) Construction of the Yellow River water and sediment change data warehouse

[0031] The annual and monthly rainfall and hydrological sediment data of the main sand-producing areas of the Yellow River, the rainfall and flood sediment data of typical tributaries, the land use and forest and grass coverage data of typical years, the terraced field data of typical years, the data of water conservancy and soil conservation projects, social and economic As well as the analysis of relevan...

Abstract

The invention relates to a construction method of a Yellow River water and sand change data warehouse and a public service platform. The construction method of the Yellow River water and sand change data warehouse comprises the following steps: step 1, carrying out decision topic demand analysis; 2, determining a decision topic information model or a concept model; 3, determining a data source related to the decision topic information model, and screening and analyzing the data source, wherein the data source comprises data from an operational database, files and other formats, spatial data, professional attribute data and management data; 4, designing a decision topic data model or a logic model; 5, determining metadata of the data warehouse, technical standards of data collection, fusionand integration and ETL implementation of the data; and step 6, carrying out physical model design including index design, storage architecture, data loading and interface design. By constructing a Yellow River water and sediment change data warehouse, the Yellow River water and sediment change trend is scientifically predicted and analyzed, and then the purpose of scientifically governing YellowRiver is achieved.

Description

technical field [0001] The invention belongs to the technical field of data warehouse construction, and in particular relates to a construction method and a public service platform of a Yellow River water and sediment change data warehouse. Background technique [0002] The in-depth application of water conservancy information technology and the continuous innovation of river basin water resources management, such as the research on the change of water and sediment in the Yellow River, have promoted the rapid development of digital river basin construction in my country, improved the modernization level of integrated management of river basin water resources, and responded to various The problem of wading has provided strong support for the sustainable development of the economy, and achieved obvious social and economic benefits. At the same time, the rapid economic and social development has brought a huge impact on water resources and water ecosystems in river basins. The v...
