The mountains of Wugui Mountain and Zhuqiling are in the south-central part of the city. The main peak of Wugui Mountain is 531 meters above sea level, which is the highest peak in the city.

The landform consists of low mountains, hills, terraces and alluvial plains and beaches of the Pearl River Estuary. Among them, low mountains, hills and terraces account for 24% of the total area, generally 10 to 200 meters above sea level, and the soil type is red soil. Plains and tidal flats account for 68% of the total area, and the general elevation is -0.5 to 1 meter. The plain soil types are paddy soil and base water. The beaches are widely distributed with coastal saline marsh soil and coastal sand. The river area accounts for 8% of the whole territory. The Xishuidao and Modaomen waterways in the lower reaches of the Xijiang River flow from the north to the south through the western boundary of the city, and the South Sea is from the Modaomen. The Hongqili waterway in the lower reaches of the Beijiang River passes through the northeast border of the city. Hongqimen exits the Pearl River Estuary. In the meantime, the ramps are criss-crossed, among which the Xiaolan Waterway and the Jilu Waterway traverse the northern part of the city, and the Hengmen Channel is connected to the Pearl River Estuary by Hengmen. The water system is divided into two parts: the plain river network and the low mountain hill network. The river network in the plain area is deeply affected by the tides of the South China Sea and has the characteristics of a typical estuary area.
