Abstract
The purpose of this study was to select the sample irrigation area suitable for agricultural irrigation water consumption statistics, and to determine the best selection strategy by analyzing the path. We use a multidisciplinary approach, including geographic information systems (GIS), crop growth models and hydrological models. Firstly, we evaluated the existing irrigated areas and found that different irrigated areas have different characteristics of land use type, crop planting structure, water resource use efficiency and so on. On this basis, we use GIS technology to determine the priority of irrigation area by analyzing the geographical features, landforms, soil types and so on. Secondly, we use crop growth model to simulate crop growth in irrigated areas, combined with historical rainfall data and irrigation data, to predict crop water requirements in different seasons.
