Xuzhou belongs to the south of North China fault block area in geotectonics. Its geological conditions and structure are not too complicated, and the frequency and intensity of seismic activity are low. ?

Judging from the crustal structure, the crustal thickness of Xuzhou has not changed much. The average depth of Mohs surface is about 36 kilometers, and the average depth of Kangmian surface is 20 kilometers, which is generally deep in the west. Look at tectonic movement again. Xuzhou belongs to a large-scale subsidence area in Subei Plain. The landform is low and flat, and the sediments in the fault basin are thick, showing the characteristics of * * * oscillation movement. Judging from the fault structure, the faults in Xuzhou area are relatively developed. According to its scale and its role in the history of geological development, the most important faults in the north and east are widely distributed. The main fault zones in Xuzhou are: Tancheng-Lujiang fault zone, Fengxian-Pizhou fault zone, so the Yellow River fault zone.

There are some hills and mountains in the middle and east of Xuzhou. The elevation of hills is generally around 100-200m, and the hilly area accounts for about 9.4% of the whole city. The hills and mountains in Xuzhou are divided into two groups. One group is located in the middle of the city, with different mountain heights. Dadong Mountain in central jiawang district is the highest peak in the city, with an altitude of 36 1 meter.

Annual temperature 14℃, annual sunshine hours 2284-2495 hours, sunshine rate 52%-57%, annual frost-free period 200-220 days, annual precipitation 800-930 mm, and rainy season precipitation accounts for 56% of the whole year. The climate is characterized by four distinct seasons, abundant sunshine, moderate rainfall and both rain and heat. Among the four seasons, spring and autumn are short, winter and summer are long, the weather in spring is changeable, summer is hot and rainy, autumn is crisp, and cold waves frequently strike in winter.
