　　Bengbu City is located in the north of Anhui Province, 32 ° 43 ′ n to 33 °30 ′ n, 116 ° 45 ′ e to 118 ° 04 ′ e, bordering Suzhou City, Suixi County,Lingbi county and Sixian County in the north, Huainan City and Fengyang Countyin the south, Mingguang City and Sihong County in Jiangsu Province in the East,Mengcheng County and Fengtai County in the west, Huainan City in the southwestand Suixi and Mengcheng County in the northwest. The longest distance betweenEast and west of the city is 32.3 km, and the largest span between North andsouth is 23.5 km. Jinpu railway runs through the north and south from the middleof the area, and Huaihe River flows from west to East through the south.

　　Bengbu City is located in the transition zone between the Huang Huai HaiPlain and the Jiang Huai hilly region, at the end of the Jiang Huai watershed.The territory is mainly plain, with hills scattered in the South; the groundtends to the northwest and Southeast, and the natural slope is about 1 / 10000.Most of the urban area is located on the South Bank of the Huaihe River. Apartfrom the isolated bengshan (Xiaonanshan) in the center of the city, there aremore than 20 mountains in the East, South and west of the city. On 445.4 squarekilometers of land in the urban area, there are 50 square kilometers of hillsand 15.3 square kilometers of water. The landform is mainly divided into plain,hill and platform. The plain in the territory is mainly the Yellow River floodplain, and there are also shallow depression plain between rivers, low terraceof rivers with hills and beach land beside rivers. The platform is mainlydistributed in the wavy area to the south of the river, which is composed ofloess of qizui formation, and can be divided into two types: flat and inclined.Bengbu hills are mainly distributed in the south of Huaihe River, which is thenorthern edge of Jianghuai hills. The bedrock of the hill is mostly exposedafter weathering and denudation, and occasionally there are residual slopedeposits, which are basically undeveloped and coarse bony. According to theground height, it can be divided into high hills and low hills.

　　Tectonically, Bengbu sheet is located in the composite part of the secondNeocathaysian subsidence zone and the Qinling latitudinal structural zone. Itbelongs to the secondary structural unit of the Zhonghuai River platformdepression of the Sino Korean paraplatform, which is called "Bengbu platformarch". It had been uplifted obviously as early as the Sinian, and formed a landin the late Cambrian, and has been in the state of ancient land ever since.Bengbu geology experienced five periods of rapid tectonic movement, namelyBengbu period, Fengyang period, Caledonian period, Yanshanian period andHimalayan period. The Huaihe division of the North China stratigraphic arealacks the middle and late Paleozoic. The pre Paleozoic strata are dominated bymetamorphic rocks and marine strata, while the Mesozoic and Cenozoic strata aredominated by continental and volcanic rocks. The strata in Bengbu can be dividedinto upper Archean, Lower Proterozoic, Upper Proterozoic, Qingbaikou, Cambrian,Jurassic, Cretaceous, tertiary and Quaternary. The geological structure andsedimentation of Bengbu are complex. Folds formed by multiple tectonic cyclesare widely exposed. The platform dome in Bengbu area becomes the naturalboundary of Huaibei and Huainan coal bearing areas.

　　Bengbu is a transitional zone between the humid monsoon climate in thenorth subtropical zone and the semi humid monsoon climate in the south temperatezone. The monsoon is significant, the four seasons are distinct, the climate ismild, the rainfall is moderate, the light is sufficient, and the frost freeperiod is long. However, in the middle latitudes, the cold and warm air massactivities meet frequently and change greatly. In addition, the precipitation isconcentrated, and drought and waterlogging climate disasters often occur, whichhas a certain impact on agricultural production. Bengbu City is rich in sunshineand sufficient radiation heat, which can meet the needs of two crops a year. Theannual sunshine hours are estimated to be 4429.2 hours by the observatory and4440.1 hours in leap years. However, due to rain, fog and other factors, theaverage annual sunshine hours is only 2167.5 hours, and the sunshine rate is49%. The actual sunshine hours vary greatly from year to year. According tohistorical meteorological data, the sunshine hours in 1956 were the most,reaching 2461.5 hours; the sunshine hours in 1985 were the least, only 1675.1hours. The annual and monthly temperature changes in Bengbu have a certainperiodic law. The annual average temperature is 15.1 ℃, which is higher thanthat in Huaibei and Wanxi mountain areas. The annual variation of temperature isthe lowest in January with an average temperature of 1 ° C, and the highest inJuly with an average temperature of 28.1 ℃. The annual temperature difference is27.1 ℃.
