| 摘 要： | 对３０多年来１万多ｋｍ精密水准复测数百个重合点资料进行了综合研究，结果表明，广东沿海岸段的地壳平均以－０．５ｍｍ／ａ幅度沉降，表现出粤西抬升，粤东沉降，珠江三角洲大面积下沉的格局。粤西岸段平均以＋０．６ｍｍ／ａ速率上升，粤东沿海岸段平均以－０．７ｍｍ／ａ速率下降；珠江三角洲以－１．８ｍｍ／ａ速率下沉，桂东南岸段则以＋３．４ｍｍ／ａ的速上升。

| Abstract: | After complex studying the exact repeated leveling data which based on the hundreds of coincidence datum marks spread in ten thousands klms over thirty years, the results show that the crustal up-and-down movement in the shore sections of Guangdong coast is downwarping with the velocity of - 0. 5 mm/ a, and that of West Guangdong is upwarping; of East Guangdong downwarping; of Pearl River Delta downwarping in large area. The shore section of West Guangdong is uprising with the velocity of +0.6mm/a; the coast of East Guangdong downwarping - 0. 7mm/a;Pearl River Delta - 1. 8 mm/a; the shore section of Southeast Guangxi +3. 4 mm/a uprising. |
