项目摘要

We named the Tsushima Current "Ao-shio (the Blue Stream)" and have been making the investigations of the physical environments and regional cultures in the basin of this current since 1986.The Ao-shio is smaller in water quantity and slow in flow speed than the Kuroshio , but it reaches the Karafuto (Sakhalin) Island until the north latitude of 50゜. Therefore, some cultures of the southern islands and the living-forms of East-west Asia have transported and fixed on each region of Japan Sea side along this current. Besides it is characteristic that some cultures of East Asia or East-north Asia have been also propagated through the Japan Sea due to its closeness of the geographical distance. For instances on the Ao-shio region some cultures originated from the Asian Continent are very prominent such as land utilization of Makihata (alternative field of raising and cultivating) and slush and burn vultivation, surfside ships of rafts and washtubs, snowshoes and ancient ski, native oxen and horses, and so on.The Ao-shio cultures appear typically on the solitary islands such as Gotoh, Tsushima, Oki, Sado, Rishiri and so on located along the Tsushima current. In this region the cultural composites have been building as a combination of coastal and off-shore fisheries such as cuttle fishing, subsistent mixed farming, forestry such as Japanese cyperss, Japanese arborvitae, Japan ceder.To the contrary of the Ao-shio, the Liman current is coming from the north, threrfore north-origined Hamanasu appear in the Wakasa Bay and the Tango Peninsula. Also sea-lions are coming down to the south until the Noto Peninsula. It is chracteristic that in the Ao-shio region the north-origined ecological systems are overlapping with the south-origined ecological systema.

我们将对马流命名为“Ao-shio（蓝色流）”，并从1986年开始对该流盆地的自然环境和区域文化进行调查。与黑潮相比，奥潮水量较小，流速较慢，但它到达卡拉富托（库页岛）直到北纬50度。因此，一些南部岛屿的文化和东西亚的生物形式沿着这一洋流迁移并固定在日本海沿岸的各个地区。此外，由于地理距离较近，东亚或东亚-北亚的一些文化也通过日本海传播，这是它的特点。例如，在鳌尾地区，一些源自亚洲大陆的文化非常突出，如Makihata（饲养和耕作的替代领域）的土地利用和泥沼和燃烧种植，木筏和浴缸的水面船，雪鞋和古代滑雪，土牛和马，等等。Ao-shio文化通常出现在对马流沿岸的孤岛，如后藤、对马岛、冲木、佐渡、利尻等。在这个地区，文化复合材料已经建立为沿海和近海渔业的结合，如捕捞海牛，自给自足的混合农业，林业，如日本柏树，日本树，日本雪松。与澳潮相反，黎曼流来自北方，因此北源滨流出现在若正湾和探戈半岛。海狮也会南下到诺托半岛。敖绍地区具有北源生态系统与南源生态系统重叠的特点。
