摘　　要：干旱作为全球最为常见的自然灾害之一,已经对我国的农业生产造成了严重影响。为更好地预测影响作物的干旱并及时采取应对措施,综述了国内外广泛应用的各类干旱指标,包括气象指标、土壤墒情指标、作物生理生态指标及其它综合监测指标等,评述了各类干旱指标的优缺点以及在农业上的适用性,探讨了未来以作物干旱为核心的干旱指标研究拟重视的方面,以为减缓和预防干旱对农业的不良影响及制订科学的政策提供依据。Drought as one of the most common natural disaster in the world, had caused serious influence on agricultural production in China. To accurately predict the drought affecting agricultural production, this paper reviews various kinds of drought indices which are widely used at home and abroad in recent years, including meteorological index, soil moisture index, crop physiological and ecological index, and other analyzes the advantage and disadvantage of different drought comprehensive monitoring index. Moreover, this paper also indices and their adaptabilities in agriculture, and discusses the important tasks of drought index research centering on crop drought in the future, in order to mitigate and prevent the negative impact of drought on agricultural and provide reference for the manage countermeasures.
