The invention discloses an agricultural water-saving planning method based on remote sensing ET. The agricultural water-saving planning method comprises the following steps of: S1, determining an agricultural target ET of crops; S2, establishing an agricultural water-saving planning model according to the agricultural target ET of the crops, and planning a crop planting area of the whole county toobtain a county-level planning scheme; S3, decomposing the county-level planning scheme to a township-level government, further decomposing the county-level planning scheme to a village-level unit, and executing and supervising the village-level planning scheme. The agricultural water-saving planning method solve the balance problem between the actual water consumption and the actual water supplyof regional agriculture. 本发明公开了一种基于遥感ET的农业节水规划方法，包括以下步骤：S1、确定农作物的农业目标ET；S2、根据农作物的农业目标ET，建立农业节水规划模型，对整个县的农作物种植面积进行规划，得到县级规划方案；S3、将县级规划方案分解至乡级政府，再分解至村级单元，进行执行并监管；本发明解决了区域农业真实耗水量和实际供水量之间的平衡问题。
