东海沿岸潮汐汊道的P-A关系

摘要:
O′Brien方法广泛应用于砂质海岸潮汐汊道的P-A关系研究。本文运用该方法求得东海沿岸11个潮汐汉道的P-A关系为:A=2.55×10-4P0.92,lgA与lgP之间的线性相关系数为0.97。此结果的分析表明,东海沿岸潮汐汊道已接近于动态平衡;在细粒沉积物为主要物源的浙闽强潮基岩海岸,O′Brien方法也是适用的。

P-A RELATIONSHIPS OF TIDAL INLETS ALONG THE EAST CHINA SEA COAST
Abstract:
O’Brien’s method is widely used in the study of P-A relationships of the tidal inlets on sandy coasts; In the present paper, the P-A relationship of 11 inlets on the rocky coast of the East China Sea is calculated by the method. The expression is A = 2.55 10-4P0.92. The linear related coefficient between IgP and IgA, r, equals 0.97. An analysis of the result shows that the inlets have been approximated to their dynamic equilibrium. O’Brien’s method can be applied to the rocky Zhejiang-Fujian coast with megatide and fine sediments as main supply.
