These studies on carbon-14 chronology and palynology of Holocene sediments in southern Fujian along the western coast of the Taiwan Straits show that the natural environment has undergone three stages of development during the Holocene. From Early Holocene to Middle Holocene and then to Late Holocene, sediments varied from land-sea transitional to marine and then to terrigenous; vegetation altered from mixed forest to evergreen broad-leaf forest and then steppe; climate fluctuated from temperate to hot and then to warm. The sea-level maximum in the post-glacial period occurred at 5000-6000 years ago, at five to ten meters elevation. During the subsequent regression, two stable stages of sea-level dated at more than 3000 and about 2000 years ago. The climatic drying and eolian sand deposit began 700 years ago. The results agree with previous studies in southern Liaoning. -- AATA
