The terrain is long and narrow, with a length of 1.655 km from east to west and a width of 530 km from north to south. The complex landform can be roughly divided into six distinctive terrain areas. Lanzhou is high in the west and low in the south, and low in the northeast. The Yellow River flows from southwest to northeast, across the whole territory and across mountains, forming a beaded valley with alternating valleys and basins. The canyons include Bapan Gorge, Chaijia Gorge, Sangyuan Gorge, Daxia Gorge and Wujin Gorge. The basins include Xincheng basin, Lanzhou basin, Niwan-Ishikawa basin and Qingcheng-Shuichuan basin.

Winter is cold and long, the boundary between spring and summer is unclear, summer is short, the temperature is high, and the temperature drops quickly in autumn. The annual average temperature in the whole province is between 0 ~ 16℃, with different altitudes, large temperature difference, abundant sunshine and large daily temperature difference. The annual precipitation in all parts of the province is 36.6 ~ 734.9 mm, decreasing from southeast to northwest. The precipitation in the west of Wushaoling is obviously reduced, and the precipitation in Longnan Mountain area and the east of Qilian Mountain is more. Affected by the monsoon, precipitation is mostly concentrated in June-August, accounting for 50%-70% of the annual precipitation. The frost-free period in the province varies greatly from place to place. Longnan Valley is generally about 280 days, and Gannan Plateau is the shortest, only 140 days. The altitude in most places is between 1500m and 3000m, and the annual rainfall is about 300mm (40-800mm).

4. Hydrology

Lanzhou is rich in inbound water resources. The inflow of the Yellow River and its tributaries, Huangshui River and Datong River, runs through the city, reaching 33.7 billion cubic meters, with stable water volume, no ice in all seasons and small sediment concentration. The Lanzhou section of the Yellow River is 152 km, of which 45 km flows through the urban area.

5. Water resources

Lanzhou's water resources are lower than the national average, and the Yellow River and its tributary Huangshui can meet the urban industrial and agricultural water and domestic water. Lanzhou has 960 million cubic meters of groundwater every year. The total surface water resources of river runoff is 38.4 billion cubic meters, and the total groundwater is 960 million cubic meters.

In the upper reaches of the Yellow River, 25 large and medium-sized hydropower stations can be built with Lanzhou as the center, with a total installed capacity of150,000 kilowatts. Liujiaxia, Bapanxia, Yanguoxia and Daxia hydropower stations and other hydropower stations in the neighboring areas constitute one of the largest hydropower centers in China.

6. Mineral resources

By the end of 20 14, 35 kinds of deposits and occurrences at 156 have been proved in Lanzhou. There are 35 kinds of minerals in 9 categories, including nonferrous metals, precious metals, rare earths and energy minerals. Baiyin and Jinchang near Lanzhou are important producing areas of nickel, lead, zinc, rare earth and platinum group precious metals in China. Non-metallic minerals are relatively rich, including limestone, flux dolomite, flux quartzite, ferrosilicon quartzite and refractory clay. Among them, quartzite reserves are concentrated, and the transportation reserves reach 300 million tons, which provides sufficient reserve resources for ferrosilicon industry. The coal reserves are 905 million tons.

7. Biological resources

As of 20 14, Lanzhou has forestry land 182550 hectares, accounting for 13.46% of the total area, including 90 157 hectares of woodland and 770,000 hectares of natural grassland.
