Huzhu Tu Autonomous County is the only single Tu Autonomous County in China, with the largest and most concentrated number of Tu people, mainly Han people, accounting for about 17% of the total population, as well as Tibetans and Hui people. Located in the ravine on the north side of Huangshui Valley and the southwest side of Datong Valley, Huangshui River flows through the south from west to east, and Datong River flows through the east of the county from northwest to southeast.

Huzhu County is located on the Qinghai-Tibet Plateau. Solar radiation is rich in light energy resources because of its high altitude, thin atmosphere, clean air, good transparency, few clouds and reduced solar radiation through the atmosphere. It is not hot in Leng Xia in winter. Huzhu county belongs to temperate continental climate, with drought and little rain. Due to the complex terrain, great disparity in elevation, uneven horizontal distribution of heat resources and obvious difference in vertical zones, the general trend of temperature distribution is to gradually increase from north to south with the decrease of altitude.
