摘要

依据PDSI的基本原理和方法，针对甘肃中东部地区的实际情况，从建模资料长度、站点密度、可能蒸散的计算、土壤田间持水量和径流计算等几个方面对原有模式进行了修正，建立了适用于该区的PDSI并确定了权重因子，计算了20个代表站的PDSI值，并与实际的旱情记载进行对照检验，结果表明，用修正后的PDSI计算的旱度值与实际灾情基本上吻合，能较好地反映出甘肃中东部地区的干旱程度，尤其是对一些重大旱段反映明显。在此基础上，进一步分析了干旱的基本特征，为防灾减灾提供科学依据。

Abstract

On the base of fundamental and method of the PDSI ，a further modified PDSI for mid and eastern Gansu province was developed.Stations，calculation of potential evapotranspiration and runoff etc，have been revised in this index. With this modified index，the PDSI was computed at 20 representative stations from 1961 to 2000，and the computed Index was compared with the recorded drought situation. the basic characteristics of drought was analysed .It is found that the further PDSI can reflect the severity of drought in this region，and is applicable for mid and eastern Gansu.

Key words： Mid and eastern Gansu province; PDSI; Modification and application.
