摘要
遥感技术以其快速、经济和大空间范围获取的特点,已成为旱情监测的重要手段。介绍国家防汛指挥系统二期工程水利部旱情遥感监测系统的建设情况,包括旱情遥感监测模型、业务流程及系统的设计与开发等。系统实现全国旱情监测逐周生产、区域旱情1~3 d应急快速监测及逐月区域水体监测产品的生产。试运行表明全国旱情监测与国外同类产品结果一致或优于同类产品;区域旱情监测平均精度达到80%以上。最后,对旱情遥感监测系统未来发展进行展望。
As a quick,economical and wide range monitoring method,remote sensing technology has become an important means of drought monitoring.The article introduces the construction of the drought monitoring system of the second phase project of the state flood control command,including the drought remote sensing monitoring model,operation flow and the design and development of the system.The monitoring system realizes the national routine drought monitoring every week and regional emergency drought monitoring every one to three days,and monthly regional water monitoring products.System trial operation shows that the accuracy of national drought monitoring products is consistent with foreign similar products,sometimes better,and average accuracy of regional drought monitoring products is above80%.Finally,the future development of the drought monitoring system using remote sensing is prospected.
