The comparative study of prehistoric culture in the Ryukyus and around the China sea areas

本考古学研究的目的是将琉球史前文化与中国海域文化进行比较。琉球南部有台湾岛和开南群岛等岛屿。这些岛屿位于中国东南部，分为沿海岛屿和内陆岛屿，这些岛屿在河流流域中联合在一起。沿海地区共同的节日主题是：（1）适应各种环境的一些考古学问题：（2）沿海侧与内陆侧的联系。在本研究中，我们首先弄清楚与琉球和周边比较相关的研究条件。接下来，本文对华南史前文化进行了比较研究，将华南史前文化分为四个阶段（Ⅰ-Ⅳ）。中国东南部史前文化与长江流域有着密切的文化联系，但与其自然环境有着密切的联系。根据我们的研究结果，大约在公元前2000年左右，中国东南沿海地区曾有过一次活跃的文化交流。居住形式的多样化、海洋资源的多样化利用等多种发展得到了认可，成为与琉球比较研究的切入点。同时，冲绳发展了它的地域文化，其特点可以是它独特的非日本（和非绳文）起源。

The aim of this archaeological study is to compare the prehistoric culture of the Ryukyus with the cultures of the China sea areas.There are such islands as Taiwan and Kainan Islands in the south of the Ryukyus.These islands in southeast China are categorized into Islands on the coastal side and those on the inland side where they are united in the river basin.The fesearch subjects common to tlie coastal area are : (1)some archaeological problems to adapt to each environment : (2)to contact between coastal side and inland side.In this study, we first figured out the research conditions related to the comparison with the Ryukyus and the circumference.Next, we examined the prehistoric culture of southeast China in comparative study.The chronology of prehistoric south China is divided into four stages( I 〜IV).The prehistoric culture of southeast China was culturally related with the Yangtze region, although it kept originality connected to its natural environment.From the results of our study, there was an active cultuical exchange in about 2000 B.C. in the coastal side of southeast China.In those days, the various development of the diversification of the residence fomi and the diversifying utilization of the ocean resources were recognized.These became the contact views of the comparative study with the Ryukyus.At the same time, Okinawa developed its regional culture, which could be characterized by its distinctively non-Japanese(and non-Jomon)origin.
