雷州半岛舆山东半岛恰成一有趣之对比。在华北大平原之坦岸中,山东半岛呈一例外现象,多良港;而雷州半岛则在华南山岭区之崖岸中,反呈低平外貌,海港无一优良者!前者久经中外学者之探讨,而後者则寂寂无闻,其实雷州半岛之地形,尤富研究之兴趣。该区地壳最近之运动,火山之爆发,岩浆之外溢,毕露於地形上,稍俱地形之学识者,即未尝步履其地,亦可一一加以确定也。
The coastline of our country from the gulf of Peichili southward is very regular in its general cutline, presenting an arc with its convexity towards the Pacific Ocean.
