摘要

位于日本九州半封闭的有明海素来以高产量的贝壳类海产品而闻名。然而近年来这些海产品的数量急剧下降，有的物种甚至已经灭绝。其原因尚未有明确统一的认识。调研结果显示，当地居民养殖海苔时所大量使用的酸处理剂极有可能造成潮区底泥的环境岩土工程特性发生恶化，从而导致生活在底泥中的贝壳类生物大量死亡。据此我们开展了一系列现场调查和室内试验土柱试验，以测试酸处理剂对底泥的pH、硫化物含量、盐分浓度以及液限含水率的影响。结果显示，酸处理剂不仅导致底泥的pH值降低、盐分浓度降低，还导致硫化物含量的显著增高，甚至高于贝壳类生物的生命界限值。最后从磷元素在海相底泥中存在的动态形态的角度出发，探讨了底泥的环境岩土工程特性显著变化的机理。

Abstract

A study of the effect of acid treatment practice on the geoenvironmental properties of muds in the Ariake Sea tidal mud

is carried out. The results of the field tests undertaken at the Iida tidal flat site and Higashiyoka tidal flat site of the Ariake Sea and the laboratory infiltration test results are presented. It is found that as a consequence of the sea laver acid treatment practice

considerable reduction of salt concentration and pH of the muds has taken place. Furthermore

the measured increased sulfide content of the muds indicates that the acid treatment practice in the tidal flats of the Ariake Sea have produced serious consequences for some benthos inhabiting at the shallow depth of the mud. Finally

the mechanism of the observed change in geoenvironmental properties induced by the sea laver treatment practice is discussed.
