Impact Evaluation of social environment effected by natural environmental change in the large-river-Mekong River Basin

本研究试图从陆海联动环境和人类环境变化的角度，阐明洞里萨湖、湄公河及湄公河三角洲等大型湖泊的全新世沉积和全新世古地理过程。在研究领域中，位于洞里萨湖畔冲积平原上的吴哥王国的几个主要考古遗址，以及越南领土最低的湄公河三角洲，也包括了几个重要的吴哥以前的吴哥王国考古遗址。通过对JERS 1SAR和陆地卫星TM影像的实地调查和分析，利用遥感技术制作了湄公河三角洲及周边地区的地貌土地分类图，并利用水文地理信息系统对湄公河三角洲的水文过程进行了模拟，并根据地貌特征和沉积过程进行了三维模拟。

In this study, we tried to clarify for the Holocene sedimentation and Holocene paleo- geographical process of Large lake of Tonle sap lake, the grate Mekong river and also Mekong delta in the view of land-sea linkage environment and human environment change. In the study filed, the several major archaeological sites of Angkor kingdom of the grate Asia kingdom located on the Tonle sap lake side alluvial plain near Seam reap city and the lowest Mekong delta of Vietnamese territory includes also several important the archaeological site of pre- Angkor kingdom before Angkor period. Their historical successful or die-successful showed by monument and historic materials were effected by the natural environmental change under Asia Monsoon and also converted by the human activities such as the palace construction, deforestation and embankment, dam- construction.We made the geomorphologic land classification map of the Mekong Delta and surrounding area showing the flooding affected area based on the field survey and analysis of JERS 1SAR and Land sat TM Images using remote sensing technology.Also, the hydro-process of the Mekong delta was simulated by Hydro-GIS and presented 3D based on the geomorphologic feature and sedimentation process.
