A method and device for measuring water-saving potential in irrigation districts based on big data

Abstract

The present invention provides a method and device for measuring the water-saving potential of an irrigation area based on big data. The method not only considers the saving of water resources, but also ensures the balance of the ecological environment of the irrigation area and surrounding areas of the irrigation area, and protects the ecological environment and species diversity. The original hydrological cycle of the irrigation area and its surrounding areas has been maintained. By selecting dominant species around the irrigated area as a mark, while implementing agricultural irrigation and water-saving development in the irrigated area, determine and evaluate whether the water-saving technical model (irrigation parameters) implemented in the irrigated area is reasonable or not according to the growth of the dominant species around the irrigated area. It destroys the balance of the surrounding ecosystem and species diversity, etc., which can effectively avoid the destruction of the ecological balance of the irrigated area and surrounding areas and the impact on species diversity caused by excessive water saving, and realize the effective implementation of the water-saving technology model in the irrigated area. Based on the evidence, reasonable agricultural water-saving technologies and management models can be selected to better promote local economic development and protect ecological balance.

Description

technical field [0001] The invention relates to the field of agricultural irrigation, in particular to a method and device for measuring the water-saving potential of irrigation areas based on big data. Background technique [0002] Agricultural water-saving plays an important role in protecting the balance of the ecological environment and species diversity. my country's agricultural water-saving mode and water-saving technology have changed from the initial extensive irrigation mode such as flood irrigation to fine irrigation. Especially after the founding of the People's Republic of China, the development and changes of my country's agricultural water conservation, the changes in the country's concept of water control and the concept of rational use of water resources, coupled with the government's policy guidance, the construction of large-scale water conservancy projects and macro-control, have a great impact on the development of agricultural irrigation models and techn...

Problems solved by technology

[0005] However, although the implementation of agricultural irrigation and water-saving technology in the arid area of ​​Northwest China can ensure the amount of water needed for crop growth and increase food production, it has an impact on the ecosystem around the irrigation area, resulting in reduced rainfall, reduced biodiversity, and land facing desertification. Therefore, while studying the water-saving technology of agricultural irrigation, it is also necessary to study how to increase crop yields, save water resources, and It can protect the balance of the irrigated area and the surrounding ecosystem, and protect species diversity
