四川炉霍宴尔龙石棺墓出土二里冈文化的铜戈,表明川西高原最早的青铜器可能经半月形文化传播带而来。川西石棺墓中的铁器有铜柄铁剑、汉式器物和巴蜀式器物三类,其中铜柄铁剑不见于成都平原,可能同样是经半月形地带从甘肃、宁夏地区传入。正如川西石棺墓中最早的铜器并不代表二里冈文化已传播到川西高原一样,石棺墓中最早的铁器也不是中原文化或汉文化扩张的结果。川西石棺墓出土的金属器似乎说明,冶金技术由西向东的传播并非一定是先到达中原、然后再以中原为中心向四周传播。冶金技术在经半月形地带时也可能同时向南流传,从而显现出古代技术传播路线的多样性。 Sichuan furnace Huoer Er Long sarcophagus unearthed the bronze Ge of the two Rangon culture, indicating that the earliest bronze ware on the western Sichuan plateau may have come through the half-moon shaped cultural transmission belt. The iron sarcophagus in the Western Sichuan coffin tomb has three types of copper handle iron sword, Chinese-style utensils and Bashu-style utensils. The copper handle iron sword is not seen in the Chengdu Plain, and may also be introduced from Gansu and Ningxia through the half moon-shaped zone. Just as the earliest bronze vessels in the Western Sichuan sarcophagus did not represent the fact that the Erlitang culture had spread to the western Sichuan Plateau, the earliest ironwork in the sarcophagus was not the result of the expansion of the Central Plains culture or the Han culture. The metalwork unearthed from the sarcophagus in western Sichuan seems to indicate that the transmission of metallurgical technology from west to east does not necessarily reach the Central Plains first and then spread around the Central Plains. Metallurgical technology, while passing through the semilunar zone, may also spread to the south at the same time, showing the diversity of ancient technology transmission routes.
