Dingxi City is located in central Gansu province, 98 km (61 mi) east ofLanzhou, giving it the nickname the "eastern gateway". TheWei River, a tributary of theYellow River flows through the district and provides it with the majority of its water. Dingxi is semi-arid, with little precipitation. Even though sunlight here can be intense, temperatures are generally cool. The surrounding terrain is mostlyloess hills and ravines in the north and highlands in the south. The area is 20,300 km2 (7,800 sq mi).
After theQianlong Emperor period (18th century), the land of Dingxi went from lush grasslands and forests to being severely deforested as a result of war, famines and overpopulation.[5]

Dingxi has been one of the most poverty-stricken regions in Gansu province and China as a whole.[9] Up to 1999, some citizens still lacked food and clothing. Although most of Gansu is arid, in other regions of the province a large portion of farmland is irrigated, whereas in Dingxi this was not the case.[10] Especially after the 1960s, the agricultural output of Dingxi plummeted due toland degradation.[11]
Agriculture and natural resource based industries are the key to Dingxi's economy. There are more than 300 different kinds of Chinese medicinal plants and herbs found in the area. Dingxi's Anding County is China's number one grower of yams.Zanthoxylum (also calledSichuan Pepper or prickly ash fruit), walnuts, wild apricots, and other fruit are some of Dingxi's famous dried exports. Potato is an important crop, and Dingxi has been described as the 'Potato Capital of China'.[12]
The local Dingxi dialect ofCentral Plains Mandarin has only three tones instead of the normal four.[13]
