AGRICULTURAL WATER-SAVING PLANNING METHOD BASED ON REMOTELY-SENSED EVAPOTRANSPIRATION

摘要

An agricultural water-saving planning method based on a remotely-sensed ET includes the following steps: S1: determining an agricultural target ET of a crop; S2: establishing an agricultural water-saving planning model based on the agricultural target ET of the crop, and planning a planting area of the crop of a whole county to obtain a county-level planning scheme; and S3: decomposing the county-level planning scheme to township-level governments and further to village-level units for execution and supervision. The new method realizes the balance between real regional agricultural water consumption and actual water supply.
