对在内蒙古气候中心干旱监测评估业务中经常使用的降水量距平百分率、土壤相对湿度干旱指数、综合气象干旱指数三种气象干旱指标进行详细介绍和适用性分析。并对三种气象干旱指标的监测结果进行对比分析,结果认为综合气象干旱指数指标能较确切反映出干旱程度,尤其在对干旱过程的跟踪方面具有明显的优势。降水量距平百分率指标反映干旱程度较轻,土壤相对湿度指标反映干旱程度比较敏感。
對在內矇古氣候中心榦旱鑑測評估業務中經常使用的降水量距平百分率、土壤相對濕度榦旱指數、綜閤氣象榦旱指數三種氣象榦旱指標進行詳細介紹和適用性分析。併對三種氣象榦旱指標的鑑測結果進行對比分析,結果認為綜閤氣象榦旱指數指標能較確切反映齣榦旱程度,尤其在對榦旱過程的跟蹤方麵具有明顯的優勢。降水量距平百分率指標反映榦旱程度較輕,土壤相對濕度指標反映榦旱程度比較敏感。

The three kinds of weather drought index that included the percentage of precipitation anomaly,humidity drought index and comprehensive weather drought index,and were used in evaluation operation of drought monitor of Inner Mongolia climate center were introduced particularly and analyzed on applicability.The monitor result of three kinds of weather drought index were analyzed by comparative method,the results showed that comprehensive weather drought index could definitely reflect drought degree,and it had obvious superiority especially in aspect of following of drought process,percentage of precipitation anomaly reflect drought degree more light,but the relative humidity index of soil was more sensitive.
