Coastal lagoons with small catchment basins are highly sensitive to natural processes and anthropogenic activities. To figure out the environmental changes of a coastal lagoon and its contribution to carbon burial, two sediment cores were collected in Xincun Lagoon, southeastern Hainan Island and (210) ~Pb activities, grain size parameters, total organic carbon(TOC), total nitrogen(TN), total inorganic carbon(TIC) and stable carbon isotopes(δ^(13)C) were measured. The results show that in 1770–1815, the decreasing water exchange capacity with outer open water, probably caused by the shifting and narrowing of the tidal inlet, not only diminished the currents and fined the sediments in the lagoon, but also reduced the organic matter of marine sources. From 1815 to 1950, the sedimentary environment of Xincun Lagoon was frequently influenced by storm events. These extreme events resulted in the high fluctuation of sediment grain size and sorting, as well as the great variation in contributions of terrestrial(higher plants, soils) and marine sources(phytoplankton, algae, seagrass). The extremely high content of TIC, compared to TOC before 1950 could be attributed to the large-scale coverage of coral reefs. However, with the boost of seawater aquaculture activities after 1970, the health growth of coral species was severely threatened, and corresponding production and inorganic carbon burial flux reduced. The apparent enhanced inorganic carbon burial rate after 1990 might result from the concomitant carbonate debris produced by seawater aquaculture. This result is important for local government long-term coastal management and environmental planning.

苏北废黄河三角洲属淤泥质海岸类型,是我国海岸侵蚀严重的地区之一.本文根据地形图、海图、历史地图、遥感影像及历史文献等资料,应用GIS/RS技术及数理统计原理,对废黄河三角洲海岸线空间演化特征进行定量分析,以研究历史时期以来苏北废黄河三角洲岸线的整体演变特征.自春秋以来,废黄河三角洲海岸线经历了春秋至北宋的相对稳定,北宋后快速向海推进,再向陆侵蚀内移并逐渐趋于稳定的过程,这一过程主要受黄河南徙与北归的控制.1989年以来,中山河口至扁担河口岸段是主要侵蚀区,不同部位蚀退速率有差异,北部蚀退速率小于南部,中山河口以北、夸套河口以南则以淤积为主,这种差异主要受沿岸地形及人类活动的影响.
