前段时间有幸翻阅了《地球》杂志1984第2期,其中有张敏丽的“我国最大的陆连岛”一文,笔者对文中关于芝罘岛连岛沙坝的成因及时代论述有些不同看法,特提出与张敏丽同志商榷,并请广大读者指正。众所周知,沙嘴形成于沿岸海流流速突然变小的地段,通常发育在海岸的凸岸,它是海洋纵向搬运的结果。当海岸邻近有岛屿时,岛屿对波浪起着消能作用,并造成波浪的折射,形成所谓波影区,在波影区内因波能变弱,致使纵向搬运沉积物的流速和容量降低,造成堆积,这种堆积的发展使沙嘴延伸扩大,以致陆、岛相连,即为连岛沙
Some time ago fortunate enough to read the “Earth” magazine, 1984, No. 2, including Zhang Minli’s “China’s largest continent island” a text, the author of the text on the island of Zhijie Island Shaba’s theory and the times have some different views, special Proposed to discuss with Comrade Zhang Minli, and requested the majority of readers correct. As we all know, the spit formed in the coastal stream flow rate suddenly smaller section, usually developed in the coast of the shore, it is the result of the longitudinal transport of the ocean. When the coast is adjacent to an island, the island plays a role of dissipating energy on the waves and causes refraction of the waves, forming a so-called shadow zone where the wave energy becomes weaker resulting in a decrease in the flow rate and capacity of the vertically transported sediments Accumulation, the accumulation of such development to expand the expansion of sand mouth, resulting in land and islands connected, that is, even the island sand
