An irrigation area water-saving potential measurement method and device based on big data

Abstract

The invention provides an irrigation area water-saving potential measurement method and device based on big data, and the method not only considers the saving of water resources, but also can ensure the balance of the ecological environment of an irrigation area and surrounding areas of the irrigation area, protects the ecological environment and species diversity, and maintains the original hydrological cycle and the like of the irrigation area and the surrounding areas. Dominant species are selected at the periphery of an irrigation area to serve as marks; agricultural irrigation water-saving development is carried out on an irrigation area; according to the growth condition of dominant species around the irrigation area; determining and evaluating whether the water-saving technical mode(irrigation parameter) applied in the irrigation area is reasonable or not; whether the surrounding ecosystem balance and species diversity are damaged or not is judged; Thus, ecological balance damage and influence on species diversity of an irrigation area and surrounding areas caused by excessive water saving can be effectively avoided, a basis is provided for implementing a water-saving technical mode in the irrigation area, and therefore a reasonable agricultural water-saving technology and management mode are selected, and local economic development is better promoted and ecological balance is better protected.

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
