Abstract: The biogeochemical cycle of modern sedimentary phosphorus in ocean continental interaction zone and its relationship with O 2 and CO2 in the atmosphere are discussed in this paper. From enviromental biogeochemical theory and methodology, the characteristics of variation of sedimentary phosphorus with time, species, and its related elements are summarized. It can trace back to the driving factors that caused past climate and environmental changes. Furthermore, the potential influence of modern sedimentary phosphorus in estuary bay area to global climate change and regional respond is discussed. It shows that the modern sedimentary phosphorus acts as a special role in the study of globle climate change. And it could help to indicate the past climate and environmental change. The study of moedern sedimentary phosphorus will supply scientific information to the creation of the pattern of global change.

Key words: Estuary bay, Global change, Regional respond, Sedimentary phosphorus
