论文部分内容阅读
世界各地许多史前考古遗址中都出土了数量不等、生存环境不同的软体动物贝壳。自此考古学家们开辟了一个新的研究领域,即软体动物分析。在这一方面,西方学者建树颇多。如,软体动物贝壳的氧碳同位素分析已经是重建古环境的成熟的方法。在海洋环境下,氧同位素变化已经成功地用于衡量古代海面温度。日本学者自上个世纪70年代末,通过分析贝丘遗址和周围的自然环境去认识绳纹时代的环境变化及绳纹人与环境的关系。我国有着绵长的海岸线和各类内陆水体,随着近年考古发掘的蓬勃开展,越来越多的贝丘遗址及不同种属的软体动物贝壳相继出土。但学者们限于各种原因并没有充分利用这些资料,尤其是关于古人采集贝类的季节性研究较少。现将日本学者小池裕子的论文译出,意在为我国今后开展相关研究提供参考。鉴于目前国内资料的缺乏,有必要对原文使用的术语做一说明:日生长线(daily growth lines)、次生长线(secondary growth lines)、日生长纹(daily growth increments)、年生长纹(annual increments/pattern)。另外,为便于读者理解,译者对原文次序作了小幅调整。
Many mollusk shells of unequal living environments are unearthed in many prehistoric archeological sites around the world. Since then archaeologists have opened up a new area of research, mollusc analysis. In this respect, Western scholars have made a lot of contributions. For example, oxygen and carbon isotope analysis of mollusk shells has been a mature method of reconstructing ancient environments. In the marine environment, changes in oxygen isotopes have been successfully used to measure ancient sea surface temperatures. Japanese scholars from the late 70s of last century, through the analysis of Bequior site and the surrounding natural environment to understand the Jomon era of environmental change and Jomon people and the environment. My country has a long coastline and various types of inland water bodies. With the vigorous development of archeological excavations in recent years, more and more shellfish ruins and shells of mollusks of different species have been unearthed. However, the scholars did not make full use of these materials for a variety of reasons. In particular, there are few seasonal studies on shellfish collected by the ancients. Now the Japanese scholar Koike Yukie’s translation is intended to provide reference for our country to carry out related research in the future. In view of the current lack of domestic information, it is necessary to make a statement on the terms used in the original text: daily growth lines, secondary growth lines, daily growth increments, annual growth patterns increments / pattern). In addition, for the sake of reader’s understanding, the translator made a slight adjustment to the original order.
