本研究采用调查、实验、模型相结合方法，建立了区域农业干旱模型。并将其应用于区域农业干旱评价、监测及对策分析等方面。研究结果表明：气象干旱指标P/E（p-降水量，E-潜在蒸发量）不能准确表达农业干旱状况，本研究所建立的农业干旱模型经验证有广泛的适用性和准确性，对农业干旱的评价、监测与实际相符，对农业于旱理论与实践都具有一定价值。
In this study, a combination of surveys, experiments, models to establish a regional agricultural drought model. And apply it to regional agricultural drought assessment, monitoring and countermeasure analysis. The results show that: the drought index P / E (p-precipitation, E-potential evaporation) can not accurately represent the status of agricultural drought. The agricultural drought model established in this study has been proved to have wide applicability and accuracy. The evaluation and monitoring of drought are consistent with the actual situation and have some value to agriculture theory and practice in drought.
