摘　　要：为有效监测干旱灾害,使用功能强大的IDL语言,开发出旱情参数计算和统计分析的软件系统并运用于河南省旱情发展的预测和评估决策中。该系统使用MODIS 1B级产品,通过预处理、参数计算、模型建立、结果分析等步骤,最终输出旱情分级旬报产品。由于考虑了实际应用中的众多不利因素、采用了底层开发模式,该系统与其他现有旱情监测软件相比更具有实用性、可扩展性及灵活性。A new software system for effective drought disaster monitoring is designed and realized in order to calculate drought parameters and make necessary statistical analysis by using the powerful IDL language. This system is applied to the development of drought prediction and assessment of the decision-making in Henan Province . The data source is MODIS 1B level products. Different resolution data may be separately dealt with through pretreatment, parameter calculation, model creation, and output drought classification products every 10 days. Because of the considerations of the practical application and the infrastructure development of the software, the system has greatly improved in suitability, ability of update and flexibility comparing to the other known drought monitoring software.
