本文的目的是建立淡水古环境重建的环境指标。活的硅藻材料是从河流、湖泊、沼泽、高沼泽和陆地上采集的。因此，根据生境对硅藻种类进行了分类，如下所示。河流上游指示种(J)2.河流中下游指示种(K)3.河流最下游的指示种(L)4.湖泊的指示种(M)5.湖泊和沼泽的指示种(N)6.沼泽的指示种(O)7.高沼泽的指示种(P)8.利用硅藻指示种考察柳谷川平原冲积物的海洋退化过程和古环境因此，这些硅藻指示种对于重建淡水古环境是非常有用的。
The purpose of this paper is to establish the environmental indicators for reconstruction of freshwater paleoenvironments. Living diatom materials were collected from rivers, lakes, marshes, high moors and lands. Therefore, diatom species were classified on the basis of habitats, as follows.1. Indicator species of the upper stream of a river (J)2. Indicator species of the middle-lower part of a river (K)3. Indicator species of the most lower part of a river (L)4. Indicator species of a lake (M)5. Indicator species of a lake and a marsh (N)6. Indicator species of a marsh (O)7. Indicator species of a high moor (P)8. Indicator species of a land (Q)Using those diatom indicator species, the marine regression process and the paleoenvironments of upper alluvial deposits in Yanasegawa valley plain were examined. As a result, those diatom indicator species are very useful for reconstruction of freshwater paleoenvironments.
