摘要
河口海岸地区广泛生长的牡蛎壳体,作为气候环境变化的一种载体,是研究河口浅海环境演化和海陆相互作用的理想对象。本文以渤海湾地区广泛发育的太平洋牡蛎壳体为研究对象,根据现生活牡蛎壳体记录的氧同位素变化幅度和生长水体的温度、盐度,定量地计算了该地区Crassostrea gigas在冬季停止分泌/春季恢复生长的最低水温为5.5℃,生长季节为3月至12月。
Oyster reefs are widely distributed along coastal and estuary areas. The in situ living oyster shell is a good object for studying and reconstructing the climate and environment change. With a living Pacific oyster （Crassostrea gigas） shell collected from the northwest coast of Bohai Bay as the study object and according to the analytical results of stable isotope of O in the continuous growth micro-layers of the shell as well as monthly average sea surface salinity （SSS） and sea surface temperature （SST）, the authors obtained the lowest sea surface temperature recorded by the C. gigas shell in winter. In Bohai Bay area, the cease of shell growth of C.gigas lasts for up to 3 months per year from December to March, when the water temperature decreases to 5.5℃.
