An Eco-geographical Study of the Basin of the Tsushima Current - Comprehensive Regional Investigations of the Ao-shio Cultures -.

我们称之为“Ao-shio （the Blue Stream）”，并在1986年以来在本盆地进行了物理环境和区域文化的研究。Ao-shio在水数量上较小，流速比Kuroshio慢，但它到达Karafuto （Sakhalin）岛直到50 °的北方纬度。因此，南部岛屿和东西亚洲的一些生活形式在日本的每个地区都有运输和固定的，目前这些地区的海洋。这是一个特征，因为东亚或东亚北部的一些文化也被宣传为日本海，使其在地理距离上的封闭性。由于在青岛地区的一些文化起源于亚洲大陆的一些实例是非常突出的，因为Makihata的土地利用（替代养殖和养殖场）和泥浆和燃烧繁殖，木筏和洗涤槽的冲浪船，雪和植物滑雪，本土Oxen和Horses，以及其他类似的情况。AO-Shio文化似乎在孤立岛屿上如Gotoh、Tsushima、Oki、Sado，Rishiri和如此位于Tsushima的当前位置。在这一地区，文化复合物已被建设为沿海和近海渔业的组合，如切割渔业、亚混合养殖、林业如日本柏树、日本油菜鱼、日本雪松。到了与青鱼的对立中，利曼目前正从北方来，而北方起源的哈马纳苏出现在瓦卡萨湾和探戈半岛。此外，海狮也将在不半岛的南面降落。这是一个具有历史意义的现象，即在青山地区，北方原住的生态系统与南方原住的生态系统重叠。

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.
