EXCAVATIONS OF LAL-LO SHELL MIDDENS

(1)继续发掘河岸贝类，获取器物，建立当地年代学。根据研究结果，将其年代序列划分为四个时期，如红滑陶器I年代学。在此基础上，将其年代序列划分为红滑陶器I、红滑陶器II、黑陶I、黑陶器II四个时期，明确了年代序列与聚落变化的关系。(2)对C14年代、动植物遗迹鉴定、动植物遗迹季节和栖息地鉴定、地质和花粉标本进行了连续的科学分析。通过分析，我们可以得到理解史前环境开发和生存策略变化模式的关键，即Cagay…从沼泽到河流的环境变化开始了贝类的形成更像是一条河。下游贝类数量增加。(3)在两个河岸遗址，贝类遗骸均从贝类下的淤泥层中显露出来。菲律宾国家博物馆目前正在进行史前饮食的同位素分析和物理人类学分析。(4)通过同位素分析的结果，意外地澄清了史前拉洛贝类采集者的饮食依赖于陆地哺乳动物。(5)地质和花粉研究小组在河岸和内陆遗址进行了钻探，获得了每个地点的地质背景和花粉样本。(6)通过对位于丘陵地区的洞穴遗址的发掘，收集到了无定形的片状和红滑陶片。从河岸遗址的淤泥层中也发现了无定形的片状结构。我们可以获得基于不同生态环境的人类群体之间史前交流和社会关系的基本数据。关于狩猎采集者和农民相互依存关系变迁历史的民族考古学研究将在下一个田野季节进行。(7)综合生存活动模式和文物年代学，遗址分布模式从3000到1000BP。(8)菲律宾和日本考古学家在撰写报告期间积极开展思想交流，以了解这些考古特征。并对未来的研究设计进行了讨论。较少

(1) The excavations of river bank shell middens have been continued to acquire the artifacts to build up the local chronology. By the result, the chronological sequence is subdivided into four periods, such as Red-slipped pottery I chronology. By the result, the chronological sequence is subdivided into four periods, such as Red-slipped pottery I*Red-slipped pottery II*Black pottery I*Black pottery II.And st is clarified that the chronological sequence correlate to the changing patterns of settlement.(2) The scientificanalyzes of C14 datings, identification of faunal and floral remains, seasonal and habitat identifications of faunal and floral remains, geological and pollen samples have been performed continuously. By the results of analyzes, we could get the key to understand the prehistoric changing patterns of environmental exploitation and subsistence strategy, that is the formation of shell middens was begun by the environmental change from the swampy to fluvial condition of Cagay … More an River. And latter, numbers of shell midden increased in the lower river.(3) In the two river bank sites, the human skeletal remains are revealed from the silt layr under the shell midden. The isotope analysis for the prehistoric diet and the physical anthropological analysis are on going at this moment at the National Museum of the Philippines.(4) By the result of isotope analysis, it is clarified unexpectedly that the prehistoric Lal-lo shell gatherers' diet was dependent on the terrestrial mammals.(5) The geological and pollen study team performed the boring at the river bank and inland sites, and the data on the gelolgical settings of each site and the pollen samples are acquired.(6) By the excavation of cave site located on the hilly area, the amorphous flakes and Red-slipped pottery sherds are collected. The amorphous flakes are also revealed from the silt layr of river bank site. We could have the basic data on the prehistoricexchange and social relationships between human groups based on the different ecological settings. The ethnoarchaeological research on the changing history of interdependent relationships between hunter-gatherers and farmers will be held at the next field season.(7) Synthesizing the patterns of subsistence activities and the chronology of artifacts, the site distribution patterns from 3,000BP to 1,000BP.(8) The exchange of ideas among Filipino and Japanese archaeologist for the understanding of these archaeological traits are carried out actively during the report wreiting. The future research design is also discussed. Less
