摘要
干旱等级是描述一次干旱强度的定量指标，干旱灾度是描述一次干旱造成社会损失大小的定量指标。这两个指标从理论和应用方面来说具有客观、定量的优点，逻辑关系严密，概念明确，简单易行，计算方法科学，实时资料可得，具有重要的实际意义，能运用于干旱半干旱地区的干旱监测业务。
Magnitude of drought is a quantitative index for describing once drought scale, and drought disaster degree is a quantitative index for describing social economic loss caused by once drought. The two indices have the advantages of objectivity and quantification from view of theory and application, with features of logical tight, dear in concept, scientific calculating method, and the real-time data can be easy got. They are easy to be applied, and have practical significance, so that they can be applied in drought monitoring in the arid and semiarid areas.
