The whole territory is located from east longitude 1 16 14' 40 "to north latitude 1 17 19' 35" to 23' 33 ". It has always been an important transportation hub, import and export shore and commodity distribution center in eastern Guangdong, southern Jiangxi and southwestern Fujian, and is known as the "gateway to eastern Guangdong".

Topography Shantou is dominated by delta alluvial plain, accounting for 63.62% of the city's area, followed by hills and mountains, accounting for 30.40% of the land area, and terraces account for 5.98% of the total area. Shantou City is located in the coastal alluvial plain between Lianhua Mountain in eastern Guangdong and the South China Sea. The terrain in the territory inclines from northwest to southeast. From northwest to southeast, the whole terrain is in turn low mountains and Zhongshan-hills, terraces or terraces-alluvial plains or marine plains-sand ridges and sea cliffs at the front of the coast-islands. There are Lotus Hill in the northeast, Pu Sang in the northwest and Da Nan Shan in the southwest. The southeast coast of the estuary is alluvial plain or marine plain and marine erosion landform, as well as the distribution of harbors and islands. The middle and lower reaches of Hanjiang, Rongjiang and Lianjiang pass through the city, and the outlet of Sanjiang becomes an alluvial plain, which is the largest plain in eastern Guangdong. Shantou stands because of the sea and prospers because of the sea. The urban areas and counties (cities) under its jurisdiction are all by the sea. Shantou has a winding coastline and many islands. The city's coastline and island coastline are 289. 1 km long, and the working area of Shantou marine functional zone is about 6.5438+0 million square kilometers, which is five times the land area. There are 40 islands in the city, including 23 in South Australia, Chaoyang 1, Shantou 12, 2 in Chenghai and 2 in Niu Tianyang.

Judging from the existing regional geological exploration results, Shantou's regional geology is characterized by the development of Mesozoic intrusive granite, the development of Quaternary land-sea interaction and marine sediments, and the wide variety and distribution of related mineral resources. Tungsten-tin polymetallic deposits related to endogenetic ore are mainly distributed in granite distribution areas of Chenghai and Chaoyang, while quartz sand, zircon and ilmenite related to exogenetic ore are mainly distributed in coastal areas. There are abundant mineral resources in the area, such as tungsten, rare earth, glass sand, building granite, decorative granite, mineral water, underground hot water, etc., and the exploration and development prospects are very good. Tin, gold, ilmenite, zircon, monazite, kaolin and refractory clay have prospecting potential. The widely distributed granite, quartz sand and clay are important building raw material resources. The city's land resources are 224,438.7 hectares. There are 103 ports available for development in the city, including 7 deep-water ports available for development in Nan 'ao Island alone, and 69 1 ~ 65438+ 10,000-ton wharf berths can be built in 4 ports in the urban area, including Zhu Chi, Mashan, Suai and Guang 'ao. There are many ports and large shallow beaches. 10m isobath shallow beach covers an area of 743,000 mu, and the usable area is 468,000 mu. The 200-meter isobath fishing ground covers an area of 53,000 square kilometers, which is suitable for mariculture and rich in sea salt. There are 47/kloc-0 species of fish, 7 species of shrimps and crabs, more than 30 species of shellfish and nearly 20 species of algae in the offshore waters.
