珊瑚礁目前正面临自然/人为因素造成的多种干扰。最近的工业发展可能会影响珊瑚礁环境和生态系统;然而，珊瑚钙化与当地工业历史的直接比较很少。我们展示了从日本奄美大岛住代湾采集的珊瑚Ba/Ca记录和46年的生长历史。珊瑚Ba/Ca主要受两条河流引入的海水泥沙含量控制。珊瑚Ba/Ca记录具有两个明显的历史时期特征：与传统丝织业相对应的年代际波动（1960年代与1995年相似）和与采石场和建筑业发展相对应的上升趋势（1996年与1995年相似）。珊瑚Ba/Ca记录和当地工业历史也与珊瑚钙化有关。对珊瑚礁环境和当地工业变化的长期定量评估可以为今后造礁珊瑚的生存战略提供评估。
Coral reefs are currently facing multiple disturbances caused by natural/anthropogenic factors. Recent industrial development might influence reef environments and ecosystems; however, few direct comparisons of coral calcification with the histories of local industries exist. We show the coral Ba/Ca record and growth histories for 46 years collected from Sumiyo Bay, Amami-Oshima Island, Japan. Coral Ba/Ca was mainly controlled by the sediment loads in seawater, which are introduced through the two local rivers. Coral Ba/Ca records have been characterized by two distinct historical periods: the decadal fluctuation corresponding to the traditional silk fabric industry (1960s similar to 1995) and the increasing trend corresponding to the development of quarries and the construction industry (1996 similar to). Coral Ba/Ca records and local industrial histories were also linked to coral calcification. A long-term quantitative assessment of reef environments and local industrial changes could provide an evaluation of the survival strategies of reef-building corals in the future.
