Qingyang is the easternmost prefecture-level division of Gansu and is thus sometimes referred to as "Longdong". It forms an administrative peninsula, as it is surrounded, on all sides but the south, by Shaanxi and Ningxia.

There are 5 major rivers in Qingyang including the Malian, Pu, Hong, Xilang, and Hulu or "Gourd". Their combined annual flow is more than 800 million cubic meters.

History
Qingyang was part of the area where the earliest cultures along the Yellow River developed and was part of the heartland of the Qin state that would eventually unite China. It was also an important place in the communist revolution.
Meteor shower
The Ch'ing-yang event of 1490 is a presumed meteor shower that occurred in the Qingyang district in March or April or 1490 CE. If a meteor shower did occur, it may have been the result of the breakup of an asteroid. At least three surviving Chinese historical records describe a shower during which "stones fell like rain", killing more than 10,000 people. At least one report of the event is found in the Official History of the Ming Dynasty, and other journal records which describe the event are also generally considered reliable. But the official Ming Dynasty history omits the number of casualties, which has been frequently either doubted or discounted by present-day researchers. Due to the paucity of detailed information and the lack of surviving meteorites or other physical evidence, researchers have also been unable to definitively state the exact nature of the dramatic event, even examining the possible occurrence of severe hail. However Kevin Yau et al. of NASA's Jet Propulsion Laboratory did note several similarities of the Ch'ing-yang meteor fall to the Tunguska event, which would have destroyed a highly populous district. One surviving account records:
