The geological structure of Kenting National Park is divided by the Hengchun Fault, the Manzhou Fault, and the Changle Anticline, into three areas which include the northeast area to the east of Gangkou River, the central area to the south of Taiwan County Highway 200 of Pingtung and to the east of Taiwan Provincial Highway 26 as well as the western area to the west of Taiwan Provincial Highway 26.
The northeast area is mainly the Loshui Layer, the Changle Layer, and the terrace deposit layer along the Gangkou River; the central area is mainly the Kenting Formation, the Hengchun Limestone, the allochthonous block, and the Taiping Layer of Eluanbi tableland.
The western area is mainly the alluvial layer of the Dapingding tableland, the Hengchun Limestone, the Taiping Layer of the Maobitou Peninsula, the terrace deposit layer, the alluvial layer, and the alluvial layer as well as the coral reef of coastline.
he soil of this area is mostly the stony soil in the mountain part, and the stony soil is stunted due to the steep terrain and the erosion caused by abundant rain. The soil mostly contains crushed stones. Its land is used mainly for growing forests which are interspersed with weeds.
A few areas have been indiscriminately logged for farmland. Coastal plains, riverbank flats, and basins belong to alluvial soils.
Except for a few alluvial lands with gravel, all are farmlands which are the main agricultural zone in Hengchun area.
