The Heihe River Basin is the second largest inland river basin in China. During the last few decades, this region has been faced with a serious of severe ecological and environmental problems caused by rapid economic growth and climate change. Two decades ago, with the increase of population and water consumption in the upper and middle reaches, the ecological water consumption in the lower reaches was greatly squeezed, which eventually led to serious ecological disasters, such as the shrinkage of the natural oasis, the drying up of the lakes, and frequent sandstorms in the lower reaches. The sustainable development of the region has been seriously challenged. To accurately monitor changes in hydrological and meteorological variables at watershed scale and support the wise use of water resources in this region, the Heihe Remote Sensing Experimental Research Station (HRSERS) was founded in 2009. The foundation of HRSERS has greatly improved the level of scientific research and decision support in the Heihe River Basin. The main achievements include: (1) the first watershed scale (with an area of 143000 km 2) integrated observation system in China is constructed, and a large number of long-term observation data are obtained. More than 200 papers have been published using the observed dataset; (2) key eco-environmental variables in Heihe River Basin are retrieved from remote sensing data; (3) the theoretical framework and method system for the authenticity inspection of heterogeneous surface remote sensing products have been established, and some related national standards have been approved; (4) the eco-hydrological model is improved by adding glacier, snow and permafrost modular, and the eco-hydrology-economic coupling model is developed for the whole Heihe River Basin to full couple the natural processes and social processes; (5) the United Nations Sustainable Development Goals (SDGs) were monitored at the basin scale and regional scale, and provides scientific support for the sustainable development and decision-making of Heihe River Basin.
