Lize Sand Dunes Coast Introduction
The legend of the Lanyang, "the Tortoise and Snake at the Sea Entrance," refers to Turtle Island as the "tortoise" and the long stretch of sand dunes as the "snake," with Lize being a segment of it. The coastline of the Lanyang Plain is slightly concave and bow-shaped due to coastal erosion. Only the Lanyang River originates from the Snow Mountain Range and the Central Mountain Range, while the Dongshan River carries a large amount of sediment into the Pacific Ocean. The erosive power is strong, transporting a lot of materials, and coupled with the northeast monsoon that visits for more than half a year, this results in the coastline jutting out eastward in a pointed triangular delta. The accumulation process is vigorous and ongoing, creating coastal sand dunes that rise to several dozen meters in height at Lize's seaside. Due to the presence of these coastal sand dunes, rivers find it difficult to flow into the sea, leading to low-lying areas between the sand dune ridges where drainage is poor and water accumulates, forming wetlands behind. On the dunes, Phragmites australis, Casuarina equisetifolia, and Acacia confusa grow, creating a smooth expanse like a wax-polished beach, juxtaposed with the greenery on the dunes to form a stunning landscape.
