The Ministry of Water Resources deployed and carried out demonstration of remote sensing monitoring and water consumption application of agricultural irrigation area in 2022

Recently, the General Office of the Ministry of Water Conservancy issued the "Notice on the Demonstration of Remote Sensing Monitoring and Water Use of Agricultural Irrigation Area in 2022" (hereinafter referred to as the "Notice"), and decided to carry out the remote sensing monitoring and water use of agricultural irrigation area in some provinces and regions. Demonstration of quantitative accounting application.

my country ’s agricultural irrigation water selection points, wide surfaces, and large amounts are large, and the amount of water consumption accounts for more than 60%of the country's total water consumption. However, the measurement of agricultural water extraction is relatively weak, and it is difficult for traditional measurement to fully grasp the situation of agricultural water use. Learn from the experience of natural resources, agriculture and other departments, explore the use of satellite remote sensing technology, dynamically grasp the actual irrigation area of ​​agricultural irrigation and use water changes. Very necessary.

The "Notice" states that in 2022, the selection of Hebei Province, Inner Mongolia Autonomous Region, Jilin Province, Jiangsu Province (Yancheng, Yangzhou, Wuxi), Xinjiang Uygur Autonomous Region (including Xinjiang Production and Construction Corps) carry out application demonstration work to explore the establishment of agricultural irrigation irrigation irrigation Remote sensing monitoring and water consumption business new models, improve the accuracy and comprehensiveness of the statistical and accounting of agricultural irrigation water volume, and improve agricultural water supervision capabilities.

The "Notice" proposes four key tasks. First, the actual irrigation area is approved. Using the multi -source satellite remote sensing and ground observation collaboration, carry out the interpretation and analysis of the actual irrigation area of ​​2021 and 2022, focusing on significant differences and doubt areas. Actual irrigation area. The second is to determine the average water volume index of irrigation per mu. Combined with the effective use of farmland irrigation water to calculate the work and surveys of water use, determine the average amount of water consumption of irrigation acres in small irrigation areas in the area, and define the scope of the average water volume of irrigation per mu. The third is the accounting of regional agricultural irrigation. In accordance with the approval method stipulated in the "Sub -Water Statistical Survey System (Trial)" and "Implementation Plan for Using Total Water (Trial)", the average water volume and actual irrigation area of ​​irrigation acres of small irrigation areas in the determined area of ​​small irrigation areas are used to calculate the amount of irrigation water in small irrigation zones in the area; Combined with the direct reporting of large and medium -sized irrigation areas and the amount of water supplemental water supply, the calculation of regional agricultural irrigation water consumption results and rational analysis were proposed. Fourth, the new model of agricultural irrigation water volume accounting business. Explore the establishment of an agricultural irrigation water volume accounting business based on remote sensing monitoring, study and formulate the work flow and technical requirements of remote sensing monitoring and irrigation water volume, and initially establish agricultural water remote sensing supervision service platforms, make good results, accumulate experience, gradually promote experience, gradually promote the promotion Essence

The "Notice" requires that the provincial and district water administrative departments and relevant technical support units must attach great importance, effectively strengthen leadership, strengthen technical force equipment and fund guarantee, make full use of the internal external resources of the department, promote system integration and data sharing, strengthen strengthening, strengthen Scientific and technological support, effectively implement work tasks.
