Distributed observatory network connects global and regional field sites, which is one of the prerequisites in earth surface processes observation. It is a priori to keep proper operation and maintenance, and perform strict data quality control for obtaining high-quality observation data. The current study took the Heihe River Basin (HRB), the second largest endorheic basin in China, as an example to introduce the research progress of the site maintenance and data quality control of the Heihe integrated observatory networks. The introduction of the operation and maintenance procedure covers daily, 10-day, monthly, and annual time intervals; while the data quality control process consists of instrument comparison and calibration, data processing, screening and checking, among others. Taking three superstations as an example, the observation data in 2018 are presented. Finally, the achievements of the Heihe integrated observatory network are introduced. The results can serve as a reference for the field observation and data quality control of the endorheic basins along the “Silk Road Economic Belt”.

Key words: watershed observatory network, operation and maintenance, data quality control, Heihe River Basin, super station, ordinary station
