一种基于数据分析的农业灌溉用水量估算方法

本发明公开了一种基于数据分析的农业灌溉用水量估算方法，方法包括：针对每一历史年份，根据当前时段的作物需水量、降水量、起始蓄水深度以及最大蓄水深度，计算当前时段的有效降水量；基于水量平衡关系，根据当前时段的有效降水量和作物需水量，结合最大蓄水深度更新下一时段的起始蓄水深度，逐时段递推后，得到各历史年份全生育期的作物需水量序列和有效降水量序列；计算各历史年份的需水敏感度加权匹配系数；基于各历史年份的需水敏感度加权匹配系数与历史灌溉系数，建立分段线性回归模型；基于目标年份的灌溉面积和田间水利用系数，结合目标年份的灌溉系数预测值和作物总需水量，计算目标年份的灌溉用水量；提高了灌溉用水量估算的准确性。
