The alluvial plain of the Choshui River colored green is a part of the Chianan Plain colored yellow in a broad sense The borders of plains in this image are in accordance with the groundwater zones of Taiwan

The Chianan Plain faces the Taiwan Strait on the west, Taichung Basin on the north, Pingtung Plain on the southeast, and lies to the west of foothills that extend from the Alishan Mountains The area determined by dividing the groundwater zones of Taiwan is about 2,500 km2 965 sq mi2 Between broadest points, the plain is about 35 km2 14 sq mi wide and 145 km2 56 sq mi long2

Average rainfall in this area is about 1600 mm, lowest in the whole island of Taiwan, and the rainy season is in summer, thus the plain lacks rain in winter3 Rivers which pass through this region are the Peikang River, Putzu River, Pachang River, Chishui River, Tsengwen River, Yenshui River and Erhjen River These rivers flow over the plain roughly from the eastern mountainous area to the western seacoast, and discharge into the Taiwan Strait


About 6000 years ago, the lands near the seacoast of the Chianan Plain were flooded by seawater, and emerged gradually since 5000 years ago4 Several archaeological sites are located here, including some late neolithic cultures such as the Tahu Culture, which existed between 3500 and 2000 years ago The Iron Age Niaosung Culture appeared from 2000 to 500 years ago

The Hoanya people are known in written history to have lived in the northern part of Chianan Plain, and the Siraya people lived in the south5 Han Chinese began to immigrate to the Chianan Plain since the European-ruled era of Taiwan After the Koxinga defeated the Dutch to claim Taiwan in 1662, Han people ruled this region, and became the majority later Most of them came from Zhangzhou and Quanzhou of Fujian, and Chaozhou of Guangdong, in the era of the Qing Dynasty

Japanese started to rule Taiwan in 1895 In this era, the colonial government launched infrastructure and businesses on the Chianan Plain, such as the Western Line railway, the irrigation system of the Chianan Canal, and sugar production companies which were later combined into the Taiwan Sugar Corporation After the Japanese Empire collapsed, the Republic of China held Taiwan National Highway No 1 and National Highway No 3, which pass through this region, were built in the late 20th century

The Chianan Plain is a place of cultivation of wet rices and other minor food grains It is the main planting area of sugarcane in Taiwan, but sugar production is being gradually reduced6 The area can reap three rice harvests annually since the Chianan Canal was established,7 and also produces peanuts, corn, sweet potatoes and some floricultural plants and vegetables The plain was once a place of salt production, but most of the salt evaporation ponds have been abandoned in recent years Additionally, many fish farms are located along the seacoast

There are several industrial parks located in Chianan Plain, such as Changhua Coastal Industrial Park and Linhai Industrial Park Heavy industries situated in this area include oil refining, steel making and shipbuilding It also has two relatively newer high-tech industrial parks named Tainan Science Park and Kaohsiung Science Park
