摘要
文中针对目前在农业旱情实时评价指标体系中存在的两个问题,提出了用以评价作物受旱的农田旱情严重程度折算指标,讨论了用气象指标、水文指标、作物受旱指标等多项指标综合判定旱情等级时各项指标权重值的计算方法。
Aiming at two existing problems in real time assessment index system of agriculture drought situation, this paper presents the convertion index to assess the severe degree of farmland drought situation and discusses the method to compute the weighted values of multiple indexes including meteorological index, hydrological index and crop drought index etc.
