In this study, we discussed on the evolution and geo-environment of alluvial and coastal lowlands in relation to natural disasters and environmental change. The landforms of the alluvial lowlands have developed in response to sealevel and climate changes during the postglacial age.The Tsugaru, Noubi and Echigo plains were the target plains, and the sedimentation rate and the evolution process of the alluvial lowlands were discussed by 10^3 or 10^2 years.As a result, it was found that the eruption of Towada had a great influence on the geo-environmental change in the flood plain formed by the Iwaki river and its tributaties. The aggradation of flood plain sediments in the Nobi and Tenryu plains progressed after the culmination of the Holocene transgression. In the Echigo plain, the rate of the sedimentation is almost equivalent to the Holocene sealevel rise. The sedimentation rate of natural levees in the Nobi plain is about 10 times larger than that of the flood basin.Flood condition a … More nd micro-landforms of the flood plain were studied about in the plains of Thailand and Java. Flood level based on the images of RADARSAT was analyzed in relation to the topography. Based on the analysis, good relationship between flood condition and the seasonal variation of the paddy-rice planting pattern were clarified in the flood plain of central Thailand.Landform classification based on SRTM-DEM data and satellite images were done in the Thu Bon alluvial plain, central Vietnam. Good relationship between the flood condition and the topography of the plain were clarified and shown with GIS. Furthermore, formation of the acid sulfate acid soil in the Lower Central Plain, Thailand was discussed. And it was made clear that the distribution of acid sulfate soils is related to the distribution of mangrove forest which developed along the extended coastline during the middle Holocene embayment.As mentioned above, time and spatial dynamics in relation to the formation of alluvial lowland were clarified, and the relationship between the geo-environmental dynamics in alluvial and coastal plains and various issues as to natural disasters and human habitation in the lowlands were shown in this study. In addition, several researches for this study were done particularly in Southeastern Asian areas and the result may be able to contribute to the local people. Less

本文从自然灾害和环境变化的角度探讨了冲积低地和海岸低地的演变及其地质环境。以津轻平原、野比平原和越后平原为研究对象，以10^3年和10^2年为单位，讨论了冲积低地的沉积速率和演变过程，结果表明：结果表明，十和田火山喷发对岩城川及其支流形成的泛滥平原的地质环境变化产生了重大影响。在Nobi和Tenryu平原的泛滥平原沉积物的沉积进展后，全新世海侵的高潮。在越后平原，沉积速率几乎与全新世海平面上升相当。Nobi平原天然堤坝的沉积速率约为洪水流域的10倍。 ...更多信息 在泰国和爪哇的平原上研究了洪泛平原的地形和微地貌。根据雷达卫星图像分析了洪水位与地形的关系。基于SRTM-DEM数据和卫星影像，对越南中部Thu Bon冲积平原进行了地形分类。利用GIS技术，阐明了洪水条件与平原地形的良好关系。此外，还讨论了泰国下中部平原酸性硫酸盐土壤的形成。同时，阐明了中全新世海湾期沿着海岸线延伸的红树林分布与酸性硫酸盐土的分布有关，阐明了冲积低地形成的时空动态。以及地理-这项研究显示了冲积平原和沿海平原的环境动态以及低地自然灾害和人类居住的各种问题。此外，本研究还特别在东南亚地区进行了一些研究，其结果可能有助于当地人民。少
