该研究以亚马逊地理标志为对象，首次运用简单遥感技术与现代考古天文学方法，分析326个方形和矩形土方工程的方向，发现其方向选择非随机，建造者对太阳年周期有明显兴趣。
AI 中文摘要
亚马逊土方工程，也称为地理标志，是数千个人造土结构，大多为几何形状，因森林砍伐逐渐从热带森林中显现。它们可能建于公元前五世纪至公元一千年末，但对建造者文化的考古研究尚处于起步阶段。至少对于形状规则的那些，其功能似乎是仪式性而非实用性的。本文首次将简单遥感技术与现代考古天文学方法相结合来研究其方向。分析考虑了总共326个土方工程中几乎所有已知的方形和矩形结构。结果无疑表明其方向选择并非随机，建造者对太阳年周期有明显关注。
英文摘要
Amazonian earthworks, also called geoglyphs, are thousands of man-made earthen structures, mostly of geometrical shape, which progressively emerged from the tropical forest due to progressive deforestation. They were probably built between the fifth century BC and the end of the first millennium AD, but archaeological investigation on the culture of their builders is yet at the beginning. Nevertheless, a ceremonial rather than practical function seems likely, at least for those having a very regular shape. In the present paper, simple remote-sensing technique, combined with the methodological approach of modern Archaeoastronomy, are applied to study for the first time their orientation. The analysis takes in consideration virtually all known squared and rectangular structures for a total of 326 earthworks. The results show without doubts a non-random choice for their orientation and a clear interest of their builders for the annual cycle of the Sun.
