Mineral Resources
Yuncheng area has complex geological structure and abundant mineral resources. There are 21 kinds listed in the mineral reserve scale of Shanxi Province through geological exploration, which include coal, iron, gold, silver, copper, aluminum, zinc, lead, cobalt, molybdenum, mirabilite, rock salt, sodium magnesium alum, brine, flux limestone, limestone, clay, phosphorus, feldspar, glass quartz sandstone and barite. The dominant mineral resources are copper, lead, magnesium (magnesium salt, dolomite), mirabilite, limestone, marble, silica and so on.
The dominant minerals are distributed in the form of "two points and one line". One of the points refers to coal mines, limestone and dolomite that locate around Xiahua of Hejin County, junction of Pinglu County and Yuanqu County. The other point is composed of dolomite and limestone from Sanluli in the central Salt Lake area to Sanwen of Wanrong County. The endogenous minerals such as copper and iron are distributed in a linear way in the southern Zhongtiao Mountainous Area. The distribution of single minerals is relatively concentrated, and copper mine is the largest pillar of mining industry in Yuncheng, which accounts for 93.99% of the total reserves of the province, located in the border areas of Yuanqu County and Wenxi County. Limestone resources are abundant, mainly distributed in the Longmenshan-Xibaikou-Weijiayuan area of Hejin City. The average thickness of ore body is 1.5-30 meters, which is suitable for open-pit mining.
Location Circumstances
Yuncheng city is located in the south of Shanxi Province, across the Yellow River from Shaanxi and Henan provinces, adjacent to Linfen City in the north and Jincheng City in the East.

Yuncheng has a complex terrain with obvious relative elevation difference. The highest point is shunwangping in Yuanqu County, with an altitude of 2321.8m; the lowest point is horseshoe nest beside the Yellow River in Yuanqu County, with an altitude of 167m. Yuncheng has three types of landforms: mountains, hills and plains. The plain area accounts for 58.2% of the total area, and the mountains and hills account for 41.8% There are mainly four mountains, Zhongtiao Mountain, Lüliang Mountain, Jiwang mountain and Gufeng mountain, covering an area of 2674 square kilometers, accounting for 19.1% of the total area.

In winter, it is controlled by the Siberian dry and cold air flow, and the northwest monsoon prevails, characterized by cold and dry climate. In summer, it is controlled by the Pacific warm and wet air flow, and the southeast monsoon prevails, characterized by high temperature, rainy climate, concentrated rainfall, rainstorm and thunderstorm. The annual average temperature is 13.3℃, the average temperature in January is - 2.2℃, and the average temperature in July is 27.4℃. The sunshine duration is 2039.5 hours.

Hydrology Situations
In Yuncheng, there are Wuxing Lake, the largest fresh water lake in Shanxi Province, as well as natural lakes such as Nitre Lake, Tangli Beach, Yazi Pond and Beimen Beach, and two reservoirs, Shangma Reservoir and Kuchi Reservoir. Yuncheng belongs to the Yellow River Basin. There are Yellow River and Fenhe River in transit. There are 25 rivers with a drainage area of more than 100 square kilometers. The flood season is from June to September every year. Restricted by the geographical environment and climate conditions, the river flow in the region has the dual characteristics of mountain type and summer rain type. In terms of river morphology and channel characteristics, it shows that the density of gullies is high, the river system is developed, the river slope is steep and the erosion cutting is serious. Characteristics of runoff and sediment are: flood surges and falls suddenly; sediment concentration is large; annual runoff is concentrated in flood season; runoff in dry season is small and unstable.
The Yellow River enters from the west side of Hejin temple tower and runs from north to south along the Shanxi-Shaanxi Gorge. After leaving the gate of Yu, the river opens in a wide way, passing through Hejin, Wanrong, Linyi and Yongji counties from north to south. Then, it turns to east from Fenglingdu of Ruicheng County, crossing Pinglu and Xiaxian counties in, and flows out from Nianpangou in Yuanqu County. It flows through 8 counties (including cities) with a total length of 396 km, which is the largest passenger water resource in Yuncheng. The annual average runoff (Longmen station) is 31.969 billion cubic meters, and the annual average flow is 1014.4 cubic meters / second.
Fenhe River enters the county from Nanliang Village of Xinjiang County and flows into the Yellow River from Miaoqian of Wanrong County through four counties (including cities) of Xinjiang, Jishan, Hejin and Wanrong, with a flow length of 145.2 km and a drainage area of 2943km2. According to the observation data of Baidi Hydrological Station of Hejin County, the annual average flow is 33.8m3/s.
Sushui River originates from Chencunyu of Jiangxian county and flows southwest through 6 counties (including cities and districts) of Jiangxian, Wenxi, Xiaxian, Yanhu area, Linyi and Yongji. It is 196 kilometers long, with a drop of 445 meters, a longitudinal slope of 1 / 400 and a drainage area of 5774 square kilometers. According to the observation data of Zhangliuzhuang Hydrological Station, the average annual discharge is 0.54 m3 / s.
Yaoxian Canal is a man-made river channel built to protect the salt lake in history. It was excavated in the second year of the Northern Wei Dynasty (505), formerly known as Yongfeng canal. During the period of Daye in the Sui Dynasty, Yao Xian, the supervisor, changed its name to protect the normal production of the salt lake. From Wangyukou, Xiaxian County, Yaoxian Canal intercepts the waters from Liugou Valley, Sigou Valley, Diaoya River, Shijiayu, Chiyu and other valleys along the northern foot of Zhongtiao Mountain, enters into the Kuchi flood storage and detention area in the northwest, passing through the Yanhu District, Yuncheng urban area, and enters the Wuxing Lake in Yongji, with a total length of 86 kilometers, a drop of 110 meters, a longitudinal slope of 1 / 770, and a drainage area of 2127 square kilometers.
