| 摘 要： | 弧形海岸形态规律的研究是岬湾沙质海岸稳定与演变研究的重要内容。在简要回顾螺线海岸理论及其应用研究状况的基础上．根据Silvester 1970、1974年及Hsu等1989年提出的螺线海岸平衡判定准则，计算了华南34个典型弧形海岸的平面形态要素，并对判定准则在华南弧形海岸中的适应性进行了评价。结果表明，由于华南弧形海岸遮蔽岸段发育有潮汐通道，湾内存在少量沿岸输沙等因素，致使判定准则并不能用于预测华南弧形海岸的稳定与侵蚀状况。

| Abstract: | The study on the rules of arc-shaped coasts is an important content of the stability and evolution research on sandy coasts between headlands. Based on a brief review of the development in log-spiral theory and its application to the coast, the plane config-uration factors of 34 typical arc-shaped coasts in South China are computed according to the judgement rules offered by Silvester (1970, 1974) and Hsu et al. (1989). and the a-daptability of the judgment rules to the arc-shaped coasts in South China is also evalua-ted. The results show that the rules cannot be applied to forecast stability and erosion of the arc-shaped coasts in South China owing to the existence of tidal inlets in the shadow zones and a little alongshore sediment transportation within the arc-shaped bays in South China. |
