项目摘要

The purpose of this study are reconstructions of the landform and the environment on the Paleo Osaka Plain in detail by utilizing generally the geological feature and environmental data from archaeological site, and understandings of the characteristic of prehistoric sites located in Osaka plain. For that purpose, we collected basic information and the stratum data in archaeological sites, and the boring data by geological surveys, also we worked preliminary analysis for reconstructing of landform and environment in prehistoric period. From a result of these general analysis, we knew the followings.In palaeolithic period, the formation of site cluster in Paleo Osaka Plain unfolded along the upland and the hill which spread out radically from Nijozan area in which sanukite is yielded.However, most of palaeolithic sites is small, and large-scale sites regarded as base camp are concentrated around Nijozan area. The exception is Gunge-imashiro site located in the northern side of Yodo rive … More r as vast river. This site is base camp of site cluster located in the Tonda upland.There is a possibility that of some topography and an environmental condition acted on the distribution of such site clusters. In other words, because everglades and swales spread out in northeast area of Osaka plain, south side of Yodo river, site clusters in palaeolithic period were formed as surrounding this area. As a result, it is estimated that the territory of the human group parted into two areas : Nijozan area and northern side of Yodo river.Because the landforms changed busily in Jomon period, it is difficult to reconstruct routes of old rivers. Therefore, it was not possible to reconstruct old landforms widely and accurately. However, by recent investigation, it became clear that the occupation by Jomon people in a long time was performed on the alluvial fan formed at the tip of Hirakata upland. In addition, it was confirmed the beach line of the Kawachi Bay whom there was in early Jomon period located at the neighborhood of Nagahara site in southern part of Osaka plain.In early and middle Jomon periods, some sites were formed along the coast of Kawachi Bay. However, the number of sites increases rapidly in latter Jomon period. Those sites were formed on alluvial fans and natural levees around the Kawachi Lake slight highlands. Sites were formed in the places where they did not live in before middle Jomon period. As for this time, the natural topography did not change large. Therefore, it seems that the rapid increase of Jomon sites after late period was affected by social changes such as a formation of trade system as a stability of territories. Less

本研究的目的是利用考古遗址的地质特征和环境资料，详细重建古大阪平原的地貌和环境，并了解大阪平原史前遗址的特征。为此，我们收集了考古遗址的基本资料和地层资料，以及地质调查的钻孔资料，并对史前时期的地貌和环境进行了初步的重建分析。从这些一般分析的结果，我们知道以下几点。在旧石器时代，古大阪平原遗址群的形成是沿着高地和丘陵展开的，这些高地和丘陵是从产山岩的二条山地区向外扩散的。然而，大多数旧石器时代遗址规模较小，被视为大本营的大型遗址集中在Nijozan地区附近。唯一的例外是位于游渡河北侧的宫-今城遗址。该基地是位于通达高地的基地群的大本营。有一种可能是某些地形和环境条件对这种遗址群的分布起了作用。换句话说，由于大阪平原东北部、游岛河南侧分布着沼泽地和洼地，围绕这一地区形成了旧石器时代的遗址群。因此，据估计，人类群体的领土分为两个地区：Nijozan地区和Yodo河北部。绳纹时期由于地形变化剧烈，古河流的路线重建难度较大。因此，不可能广泛而准确地重建旧地貌。然而，最近的调查表明，绳纹人长期以来的占领是在平田高地顶端形成的冲积扇上进行的。此外，还确认了在大阪平原南部的长原遗址附近，绳文时代早期存在的川町湾的海岸线。绳纹时代的早期和中期，在川町湾沿岸形成了一些遗址。绳文后期，遗址数量迅速增加。这些遗址是在川池湖周围的冲积扇和天然堤防上形成的。绳纹时代中期以前，在他们没有居住过的地方形成了遗址。此时，自然地形变化不大。因此，后期绳文遗址的迅速增加似乎是受到了作为领土稳定的贸易体系形成等社会变化的影响。少
