Abstract:

Historical coastline changes are very important in the coastal area study, which will benefit on utilization, development and protection of coastal areas. In this article, Jiangsu coastal areas are selected as the research area to perform a-1000-years' historical coastline evolution analysis from the South Song Dynasty in ancient China to recent years. Based on the historical coastline analysis, the underlying spatio-temporal evolution mechanism is explored. Firstly, Jiangsu coastal areas are divided into six subdivisions according to the physical geographical conditions and its historical geomorphologic changes. Secondly, Digital Shoreline Analysis System (DSAS) is used to build 356 effective coastline transacts and historical coastline changes are calculated for each transact. Thirdly, quantitative analysis and qualitative analysis are used to analyze the coastline spatio-temporal change in different historical periods. Finally, the driving forces of coastline historical change are revealed according to the above analysis. The study shows that the old Huanghe River changes severely and the maximum deposition rate and erosion rate reach 250 m/a, 600 m/a respectively. And the most important driving forces for the Millennium’s coastline changes are the historical events such as “The Huanghe River captured the Huaihe River” in 1128 AD and “The Huanghe River returned to the north” in 1855 AD and in modern times, as the major human activities, “Demolishing Salt-making Stoves and Cultivating Land” have more significant impact on the Jiangsu coastline change, resulting in the north and south radiate shoal changing obviously.

Key words: coastal areas, coastline changes, historical evolution, spatio-temporal analysis, Jiangsu Province
