Geomorphological approach to the location of ancient Khmer capitals and reconstruction of their production system

本研究旨在从自然科学和地貌学的角度阐明柬埔寨及其周边地区的前吴朝（5-9世纪）首都的位置。利用航拍和遥感资料，通过地貌和土地利用、沉积物取样、分析和定年、考古沟调查等方法开展了野外调查。因此，我们通过分析洞里萨河流域森河漫滩的微地形和沉积物，讨论了柬埔寨中部Sambor Prei Kuk考古遗址的位置。此外，我们还在老挝Sambor Prei Kuk和Wat Phou的考古沟中进行了研究，用C-14定年来澄清地层和年龄。这项研究的结果在2011年的国际学术会议上发表，并发表在Nagumo et al.（2010）和Nagumo et al.（2011）等国际期刊上。

This study aims to clarify the location of the Pre-Angkorean(5-9th century) capital cities from the field of natural science and geomorphology in and around Cambodia. Using aerial photography and remote sensing data of the target area, we carried out field survey by the method of geomorphology and land use, sampling, analysis and dating of sediment, and archaeological trench investigation.As a result, we discussed the location of the Sambor Prei Kuk archaeological site in Central Cambodia, by analysis of microtopography and sediments of the floodplain of Sen river in Tonle Sap River basin. In addition, we conducted research in archaeological trenches in Sambor Prei Kuk and Wat Phou in Laos, to clarify the stratigraphy and age with C-14 dating.The result of this research was presented at the 2011 INQUA Congress etc, and published in international journals such as Nagumo et al.(2010) and Nagumo et al.(2011).
