| 摘 要： | 以吉林省玉米为例，分析探讨了依据作物产量与蒸散量之间的相互关系，并以减产幅度为指标对自然状态下旱作物受旱灾情进行了估测。与干旱指数法、受旱面积统计法相比，该法更能较真实地反映干旱对农业生产的影响程度，可为旱田抗旱灌溉决策提供科学的依据。经实测资料检验，该方法具有较好的估测精度和区域代表性。

| Abstract: | The droughts disaster estimation of dry land crop in natural situation is studied based on relationship of crop yield and evapotranspiration and yield decreasing range as index and corn as example in Jilin province. By comparision with droughts index and droughts area statistic, the method presented can really explain effects of droughts to agricultural production and provide a scientific basis for drdughts resisting irrigation decision of dry land. The method has better estimation precission and regional representive through measured data examination. |
