The terrain of Fujian is dominated by mountains and hills, and the western and middle mountain belts constitute the skeleton of Fujian's terrain. The two mountain belts are in a northeast-to-southwest trend, parallel to the coast. In Fujian, mountains and mountains are high, and valleys and basins are interspersed among them. Mountains and hills account for more than 80% of the total area of the province, known as \"eight mountains, one water and one field\". The terrain is generally high in the northwest and low in the southeast, and the cross section is slightly saddle-shaped. Due to the control of the neocathaysian structure, the Minxi-Dashan Belt and the Minzhong-Dashan Belt are formed in the west and central parts of the province in the north (north) east direction.

Meandering near the border of Fujian and Jiangxi, the western Fujian Mountain belt consists of Wuyi Mountain Range and Shanling Mountain Range, connecting Xianxia Mountain in Zhejiang Province to the north and Jiulian Mountain in Guangdong Province to the south, with a length of more than 530 kilometers and an average altitude of more than 1,000 meters, which is the watershed of the water system of Fujian and Jiangxi provinces. The mountain belt is high in the north and low in the south, with many peaks over 1500 meters. The main peak, Huanggang Mountain, is located in Wuyishan City, with an elevation of 2158 meters, and is the highest peak in the coastal provinces of southeast China. In the mountain belt, there are many passes formed because of the collapse of faults or the elevation of ancient river valleys, commonly known as \"pass\

The Minzhong Mountain Belt, which runs diagonally through the central part of Fujian Province, is cut into three parts by the Minjiang River and the Jiulong River. Jiufeng Mountain range north of Minjiang River main stream; Between Minjiang River and Jiulong River is called Dayun Mountain Range; To the south of the Jiulong River is Po Ping Ling. The middle part of the mountain is the highest and widest. The main peak of Dayun Mountain in Dehua, 1856 meters above sea level, is the highest peak of Minzhong Mountain belt.

With the main mountains of the two mountain belts as the ridge stem, they extend many branches in all directions, forming criss-cross peaks and ridges. Outside the mountain and the coastal zone, there are widely distributed hills. They are found on the sides of river valleys, on the sides of basins, on coastal headlands, coastal plains, and among lofty mountains. There are disconnected valleys and basins between the two mountain belts, and hills, platforms and coastal plains along the eastern coast. The land coastline is 3752 kilometers long, with erosion coast as the main, accumulation coast as the second, and the coastline is very tortuous. The area of the tidal flat in the intertidal zone is about 200,000 hectares, and the bottom material is mainly mud, sediment or sand mud. There are many harbors, from north to south there are Shacheng port, Sandu 'ao, Luoyuan Bay, Meizhou Bay, Xiamen Port and Dongshan Bay, such as 6 deep water harbors. There are more than 1,500 islands scattered all over the island, Pingtan Island is now the largest island in the province, and the original islands such as Xiamen Island and Dongshan Island have built seawalls and connected with the land to form a peninsula.

In the coastal areas, there have been many transgressions and regressions in the recent geological history, forming multi-level coastal terraces and Marine erosion platforms of different heights. The original ancient bay formed an alluvial and Marine plain due to the interstacking of rivers and seas. The famous Fuzhou Plain, Putian Plain, Quanzhou Plain, Zhangzhou Plain, with a total area of 1865 square kilometers, is the most developed economic and cultural area in Fujian.
