摘　　要：河旁贝丘遗址是广西新石器时代早中期的一种重要文化遗址类型,目前对其生业状态和定居模式的研究还相对薄弱。本研究使用综合性植物考古学研究方法,对邕江流域豹子头、石船头和那北咀这3个河旁贝丘遗址进行了大遗存分析、薄壁组织(parenchyma)遗存分析、炭屑分析以及淀粉粒和植硅体等微体遗存分析。本研究的分析结果与以往的研究成果表明,邕江流域河旁贝丘群体的食谱范围非常广泛,且包含了多种回报率档次差异极大的食物资源,其生业模式应为广谱采集。磨石、陶器、炭化食物遗存的发现以及对棕榈的强化利用行为,表明贝丘群体已经具备改造环境、提高多种食物资源回报率的能力,但是对植物资源的强化利用程度仍然较为初级。贝丘群体掌握了新的食物收获和处理技术,并且可能意识到某些资源的可预测性,这为贝丘群体降低流动意愿乃至定居下来提供了基础条件。贝丘遗址可能是作为采食群体定期或季节性的定居点,以便于采集坚果、棕榈、块茎和贝类等资源,而非作为永久性的定居居址。The riverside shell midden site is an important cultural type of archaeological site in Guangxi in the early and middle Neolithic Age.There have been few studies of plant utilisation in southern China,especially for the period before the introduction of rice farming to Guangxi.The results of archaeobotanical and palaeoecological assessments of three freshwater shell middens-Baozitou(22°46'25.0″N,108°19'46.4″E),Shichuantou(22°46'18.6″N,108°23'39.3″E)and Nabeizui(22°47'53.4″N,108°30'19.6″E)-that are located along the Yong River in Nanning City,Guangxi,provide significant data on pre-agricultural subsistence status in southern China.Multiple archaeobotanical methods were applied in this study,including the analyses of macrobotanical remains,archaeological parenchyma,microcharcoal,starch grains,and phytoliths,as well as radiocarbon dating.The radiocarbon dating results have refined the chronology of freshwater shell middens in the Yong River Basin.Based on the calibrated dates of the shells,Baozitou dates to ca.12000~11130 cal.a B.P.,Shichuantou to ca.11250~10500 cal.a B.P.and Nabeizui to ca.11060~9560 cal.a B.P.These are maximum ages for the occupation at these middens,and their real ages could be overestimated by up to more than 1000 years due to the freshwater reservoir effects.Nonetheless,the three studied shell middens were all used during the Early Holocene.Each shell midden was used for a maximum of 750 years to 1500 years,although probably for much shorter occupation periods.The periods of use for the three sites show significant overlaps.Phytolith and microcharcoal results indicate that palaeoecological trends present in different ways at each site during the period of the occupation.Baozitou and Shichuantou share more similarities in the transformation of the local environment,which is characterised as cumulative decreases in forestland and concomitant increases in grassland with persistent burning over time,whereas Nabeizui exhibits opposite trends to the other sites-namely,an increase in
