摘要/Abstract

摘要：

利用主成分分解方法对华南34个典型弧形海岸线形态指标进行研究，同时分析华南弧形海岸的沉积、动力及其地貌等特征，结果表明：(1) 华南弧形海岸的形态具有多样性与复杂性特征。(2) 波浪的入射方向对海岸的形态发育不起作用，海湾的开口和波浪强度是海岸形态发生变化的重要因子。(3) 华南弧形海岸体系的地貌发育模式一般由堡岛、潟湖及其潮汐通道组成，并主要可分为海湾偏E型、海湾偏S型、海湾偏W型和海湾偏N型等4种发育模式。

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
