福建平潭大练岛西南海域沉船文物环境腐蚀性监测与评估

随着近年来文物开采力度的加大,作为自古以来沉船事故的高发区,平潭海域沉船海区的腐蚀环境越来越受到关注。本研究根据福建平潭大练岛西南海域海水及沉积环境要素的调查结果,分别进行灰关联分析及腐蚀性综合评分,综合评估了该海域对铁质文物的腐蚀性。结果表明,福建平潭大练岛西南海域海水腐蚀性为中等偏弱,沉积物腐蚀性总体处于中等水平,本研究可为福建平潭大练岛西南海域的沉船铁质文物挖掘和保护提供重要参考。

Corrosivity monitoring and evaluation of seawater and sedimentary environments around a shipwreck area in Pingtan sea, Fujian Province

As a high accident area of shipwreck from ancient times, marine environmental conditions in Pintan shipwreck area attract more and more attention under high-strength exploitation of cultural relics. Based on the survey results of environmental factors and mathematical analysis, environmental corrosivities of seawater and sediments for iron artifact are comprehensively evaluated around a shipwreck area in Pingtan sea in this study. The evaluation results show that the seawater corrosivity of Pingtan is moderately weak and the corrosive quality of sediments is at a medium level, which provide an important information for the exploitation and protection of shipwreck iron artifact in Pingtan sea area.
