摘要
简要介绍了与泥质海岸带现代地质环境变化有关的最新研究结果,包括地质历史时期全球气温与海面的变化、21世纪海平面上升趋势预测、极端高水位、新奥尔良实例等。根据对前人成果的综合研究和小组获得的最新数据,阐明了影响渤海湾西岸环境变化的主要因素——保有高程、加积作用、地面下沉、海面上升和以极端增水为代表的突发事件——各自的现状,提出了综合诸因素相互作用的泥质海岸带的研究思路和警惕可能的沼泽化趋势的建议。
The paper briefly introduces the latest research xesults concerning the changes of the modem geo-environment along the muddy coast, including the global climate and sea level fluctuations in the geological history, projections of the sea level rise in the 21st century, extremely high water levels and New Orleans and the Netherlands cases. Based on an innovative extension of previous studies and the latest data obtained by the authors＇ group, this paper presents the main factors influencing the geo-environmental changes on the west coast of the Bohai Bay, including existing altitudes, vertical sedimentation rates, land subsidence, sea level rise and sudden events such as extreme accumulated water increase. Furthermore, the authors present the idea of studying the muddy coast by considering the interaction of various factors and a suggestion of maintaining vigilance against the possible paludification trend along the muddy coast.
