摘要

This paper presents a 40000-year-long high-resolution mangrove record from sediments of Core 18300, 18302 and 18323 on the continental shelf of the southern South China Sea and reconstructs the coastline changes on Sunda Shelf since the last 40000 years. In the period Marine Isotope 3, the old Sunda Shelf had low sea level, and it was partly exposed. Flourishing vegetations grew on the exposed old land. Mangroves developed along the coastline. On the Last Glacial Maximum, the sea level dropped greatly, coastline moved from inner shelf to outer shelf, the Old Sunda Land exposed further, and the lowering sea level induced the gradual disappearing of mangroves from the inner Sunda Shelf to the outer Sunda Shelf. And pioneer vegetation ferns covered the broadly exposed old land immediately. At the time of the last Deglaciation, sea level rose greatly, the coastline moved to the sea and the Sunda Shelf was drown again. Mangroves were emergent again from outer shelf to inner shelf and developed quickly.
