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

本考古研究的目的是将琉球的史前文化与中国海域的文化进行比较。琉球南部有台湾和开南群岛等岛屿。这些位于中国东南部的岛屿被划分为沿海岛屿和内陆岛屿，它们在江河流域中结合在一起。沿海地区共同的研究课题是：(1)适应两种环境的考古学问题：(2)沿海与内陆的联系。在本研究中，我们首先了解了与琉球及其周边地区比较的相关研究条件。其次，本文对中国东南中国的史前文化进行了比较研究。史前南中国的年表分为四个阶段(I~IV)。中国东南部的史前文化虽然与其自然环境保持着原始的联系，但在文化上与扬子地区有关。从我们的研究结果来看，公元前2000年左右，中国东南沿海地区的文化交流活跃起来。当时人们认识到了居住形式多样化和海洋资源利用多样化的不同发展。这成为与琉球比较研究的联系点。同时，冲绳发展了其地域文化，它的特点可能是其独特的非日本(和非绳索)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.
