摘要
随着水文自动测报系统的快速发展,其数据质量的优劣日益重要。根据安徽省水文自动测报系统雨水情数据处理机制,分析了现有数据质量控制措施,结合使用效果指出存在漏警、虚警等短板,提出使用历史最大雨强和历史最大水位变率使阈值判断做到“一站一值”从而完善数据质量控制的对策建议,并对今后数据质量控制模式进行了思考。
With the rapid development of hydrologic automatic measuring and forecasting system,the quality of data is becoming more and more important.According to the data processing mechanism of hydrological automatic measuring and forecasting system in Anhui Province,this paper analyzes the existing data quality control measures,identifies the shortcomings according to the application effect,and proposes some countermeasures and suggestions to improve the data quality control by using the historical maximum rainfall intensity and historical maximum water level variability to make the threshold index site-specific.In addition,the future data quality control mode is considered.
