摘　　要：为了便于开展干旱研究,客观有效地进行干旱评估、损失估算和抗旱效益分析,需要开发满足抗旱减灾业务需要的干旱评估分析系统。在干旱研究的基础上,运用GIS数据平台及其强大功能开发了一套集干旱评估、干旱灾害专题图自动绘制、灌溉效益计算等于一体的软件系统。江苏省徐州市的应用表明:该系统的干旱评估结果与实际旱情比较吻合,能够为抗旱决策提供科学的技术支撑。In order to study the drought condition and carry out the drought assessment, loss estimation and drought fighting benefit analysis objectively and effectively, a drought assessment and benefit analysis system is developed to meet the need of drought mitigation. A software system integrating the functions of drought assessment, automatic drawing of drought chart and irrigation benefit calculation is developed using GIS. The application of the system in Xuzhou City shows that the estimation results are consistent with the actual situation.
