1·The paper is to study the fluvial process based on GIS by cross-section methodology.

本文主要研究基于GIS的河床演变断面分析方法体系。

2·However, the traditional analysis of data is inefficient which can not pick up the fluvial process information fully from the channel data.

传统的实测资料分析法存在分析效果差、效率低的缺陷，不能充分利用河道测图提取河床演变信息。

3·Based digital Terran information, river information application systems would be developed, such as erosion-deposition analysis, fluvial process, engineering planning and evaluation etc.

在数字地形的基础上可开发各种河道信息应用系统，如冲淤分析、河床演变、工程规划、灾情评估等。

4·The quantitative research of geomorphologic evolution in bedrock channel fluvial landscape plays a significant role in the discussion of the relationship among tectonics, climate, and surface process.

基岩河道流域地区的地貌演化定量化研究在构造-气候-表面过程关系的探讨中具有十分重要的意义。

5·Urbanization may cause the change of fluvial geomorphological process system and aggravate the soil erosion and the flood threat.

城市化可能导致流水地貌过程系统的变化，加剧水土流失和洪水威胁；

6·Based on these, the isochronal stratigraphic framework of Fuyang reservoir is established, and the fluvial-delta sequence feature and evolution process are studied in this paper.

在此基础上，运用地层基准面原理，建立扶杨油层的等时地层格架，研究其河流-三角洲层序发育特征及其演化过程。
