Abstract

Abstract:

Coastline configuration indexes of 34 arc-shaped coasts in South China were investigated by the method of principal component analysis, and meanwhile deposition and geomorphology features of arc-shaped coast were also analyzed. The results show: (1) Configuration of arc-shaped coast in South China is of the characteristic of variability and complexity. (2) Its decisive factors for the openings of the bay and wave power result in the changes of the configuration of the arc-shaped coast in South China, however, incidence direction for the wave has no effect on configuration development of the coast. (3) Geomorphologic modes of the arc-shaped coast system in South China consist of barrier, lagoon and tidal-inlet. The types for arc-shaped are classified into four kinds as follows: the openings of the bay leaned to east, the openings of the bay leaned to south, the openings of the bay leaned to west and the openings of the bay leaned to north.

Key words: coastline configuration, geomorphologic mode, arc-shaped coast, principal component analysis, South China
