摘　　要：为提高基层水文测站的测验效率,根据《水文巡测规范》(SL 195-2015)要求,文章选取了莲花水文站2020—2024年水文资料进行间测分析研究。通过对莲花水文站测验设施设备,断面稳定性,定线误差及年、时段、次洪量分析,发现水位23.00 m以上可定综合线且各误差均符合规范要求,可停2-5年测1年;水位23.00 m以下每年施测3-5次,定出低枯水临时曲线;超过27.30 m按超标预案开展测验。资料整编时,23.00 m以上采用综合线推流,23.00 m以下采用临时曲线法定线推流。To enhance the production efficiency of the Poyang Hydrology and Water Resources Monitoring Brigade,inaccordance with the requirements of the“Hydrology Survey Specifications”,this study selects hydrological data from theLianhua Hydrological Station spanning nearly five years from 2020 to 2024 for intermittent measurement analysis.Through analysis of the testing facilities and equipment,cross-section stability,alignment error,and annual,seasonal,and flood volume at the Lianhua Hydrological Station,it is found that a comprehensive line can be established above awater level of 23.00 m,and all errors meet the specification requirements.It is possible to suspend measurements for 2-5 years and conduct measurements once a year.For water levels below 23.00 m,measurements should be conducted 3-5times a year,and a temporary curve for low and dry water periods should be established.During data compilation,acomprehensive line is used for flow calculation above 23.00 m,and a temporary curve method is used for flowcalculation below 23.00 m.
