序在中国辽宁省西部地区,春秋战国时期出现了与中国式典型铜戈不同的异形戈,上下胡大幅展开呈三角形,本文把这种铜戈称之为“辽西式铜戈”。辽西式铜戈虽然以前没有提起,从其形式看好像是朝鲜式铜戈和日本铜戈(日本铜戈也属于这个谱系)的祖型。关于朝鲜式铜戈和日本铜戈的起源,目前尚不清楚,辽西式铜戈中形式与朝鲜式铜戈相近的铜戈可上溯到公元前5世纪,这样,朝鲜式铜戈本身的年代也可上溯,所以,根据对辽西式铜戈的研究,可以解决二个大问题,一是朝鲜式铜戈和日本铜戈的起源问题,二是朝鲜青铜器文化与弥生文化的年代问题。本文是根据 Preface In the western part of Liaoning Province of China, there appeared different shaped geogas different from the typical Chinese bronze gens during the Spring and Autumn Period and the Warring States Period. The upper and lower Hu greatly expanded in a triangular shape. This paper calls this copper geoglossum “western Liaoning copper genus.” Although the western Liaoning bronze Ge did not mention before, it seems from its form that it is the ancestral genre of the Korean-style copper Ge and Japanese copper Ge (the Japanese copper Ge belongs to this pedigree). With regard to the origins of Korean-style copper gens and Japanese copper geogs, it is not yet clear that the copper-clad geogrids of the Western-style copper genre that are similar to Korean-style bronze geogas can be traced back to the 5th century BC. In this way, Therefore, according to the research on Liaoxi-style copper goats, two major problems can be solved. One is the origin of Korean-style copper goats and Japanese copper goats, and the second is the issue of Korean bronze culture and Yayoi culture. This article is based on
