There are only a few scientific data about the function of ecosystems after tsunami disasters. The ecosystems help the environment to recover after a disaster, and therefore, the research on its function is important. We estimated the seawater influences on wood degradation after a tsunami disaster by the growth of Trametes versicolor. The debris from the Great East Japan Earthquake on the pacific coast in March 2011 was used for the simulations. Its growth on debris was compared with those on seawater-treated woods, and the amount of sodium chloride was examined to know the approximate amount of salts in the samples. Sodium chloride contents were employed as an indicative parameter of sea salts, which contained many elements. As a result, this common white-rot fungus degraded wood debris in the same way as sound sapwood. Although the study was conducted at the laboratory level, this is the first report from the real debris, which assessed the fungal decomposition ability of the ecosystem after a tsunami disaster.
关于海啸灾难后生态系统功能的科学数据很少。生态系统有助于环境在灾难后恢复，因此对其功能的研究很重要。我们通过变色栓菌的生长来估计海啸灾难后海水对木材降解的影响。2011 年 3 月日本太平洋沿岸大地震的残骸被用于模拟。比较了它们在残骸和经过海水处理的木材上的生长情况，并检查了氯化钠的含量，以了解样品中盐的大致含量。氯化钠含量被用作海水中所含多种元素的盐的指示参数。结果表明，这种常见的白腐真菌以与健康边材相同的方式降解木材碎片。虽然这项研究是在实验室水平上进行的，但这是第一个从实际残骸中评估海啸灾难后生态系统真菌分解能力的报告。
