The terrain of this area is plains surrounded by mountains and rivers. The east is the southern section of the Central Mountain Range, which endlessly undulates next to the plain and acts as a barrier. The west is a fertile plain, connecting the Gaoping River Basin at the county boundary and forms sloping topography. The mountains and plains are divided by the Chaozhou fault zone, which runs from north to south. The scope of this starts from the flat land in Ligang and Jiuruzhi in the north; extends from the Donggang, Linbian and Fangliao coast to the south, with Gaoping River in the west, and banana fields in the east. It is commonly known as the Pingtung Plain and is formed by the alluvial plain rivers network of Gaoping River, Qishan River, Laonong River, Linbian River and Ailio Township. The geology is composed of gravel, sand and clay soil layers, making it suitable for agriculture.
