项目摘要

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

在这项研究中，我们讨论了与自然灾害和环境变化有关的冲积和沿海低地的进化和地理环境。冲积低地的地面是为了响应冰期冰期时代的海升和气候变化而发展起来。Tsugaru，noubi和echigo飞机是目标计划，而沉积速率和沉积率和相似低地的进化过程在10^3或10^2年之间进行了批评。伊瓦基河及其支流形成的洪水平原。在全新世犯的高潮之后，NOBI和Tenryu布局中洪水平原沉积物的聚集进展。在Echigo平原上，沉积物的速度几乎等同于全新世海平面上升。 NOBI平原上自然水平的沉积速率大约是洪水盆地的10倍。根据地形分析了基于Radarsat的图像的洪水水平。基于分析，在泰国中部的洪水平原上阐明了洪水状况与帕迪雷斯种植模式的季节性变化之间的良好关系。基于SRTM-DEM数据和卫星图像的地面分类是在越南中部的Thu Bon Bolluvial Plain中进行的。洪水状况与平原地形之间的良好关系被阐明并用GIS显示。此外，讨论了泰国下部平原下酸硫酸盐酸土的形成。而且清楚地表明，硫酸盐土壤的分布与在全新世胚胎期间沿着延伸的海岸线发展的红树林的分布有关。如上所述，与冲积低地形成有关的时间和空间动力学澄清了，以及在各种沿海地区和人类计划中的地理环境动力学之间的关系和各种问题与人类的习惯和人类之间的习惯和人类之间的习惯与自然和人类的研究之间的关系。此外，这项研究的几项研究尤其是在东南亚地区进行的，结果可能能够为当地人民做出贡献。较少的
