近二十年来海面变化的区域性经验研究表明,确实无法找到一条公认的全球一致的海面变化(eustasy )曲线。为了解释共原因,地质学家与地球物理学家、数学与力学家相结合,对海面变化的机制进行了探讨。
本文着重介绍了以J.A.Clark为代表的负荷模式和以N,-A.Morner为代表的重力模式。前一模式从扩一大的冰川均衡作用和水均衡作用出发,为粘弹性地球提出了一个数学模型,计算结果表明,即使在假定5000年来eustasy不变的前提下,也可以划分出六个具有不同全新世海面变化带的曲线带。后一模式则根据测地卫星所获得的大地水准面图具有近200米的隆凹,论证了不同时间尺度的大地水准面海面变化及其可能的原因。
