During recent field survey work in Aleipata on the southeast coast of the Independent State of Samoa several new archaeological features have been discovered by a LiDAR-guided ground survey. The survey confirmed evidence from LiDAR images of a dense habitation zone from the coast to several kilometres inland with an extensive drainage system. We suggest that prior to the nineteenth century, when Samoan political organisation was first described, the extent and interconnectivity of the channels suggest that a larger population, a more intensive organisation of labour and resources for agricultural production, and a more extensive system of political authority existed.

萨摩亚（Sāmoa）过去有集约农业吗？LiDAR的新发现

在萨摩亚独立国东南海岸的Aleipata的近期实地调查工作中，由LiDAR引导的地面调查发现了一些新的考古特征。这项调查从LiDAR影像中证实了证据，该影像显示了从沿海到内陆几公里的密集居住区，并设有广泛的排水系统。我们建议，在19世纪之前，首次描述萨摩亚政治组织时，渠道的范围和相互联系表明，人口更多，农业生产的劳动力和资源组织更密集，政治权力体系更广泛存在。
