Abstract:

As one of the consequences of historical fluvial evolution, river terrace has recorded some information about environmental changes during river processes. It is the significant geomorphologic complex for analyzing river' s historical evolution. This work gives a review on the origin, geomorphologic characteristics, causes of formation, environment responses and the datemeasure technology of river terraces as well as its significance in reconstruction of environment during terrace formation. It shows that river terraces are the integrative consequence of the river system and related environment influences. Researchers should consider the entire river system and its environment syntheses to study river terraces. The geological tectonic and climate characteristics and ancient river dynamics may be revealed according to research of river terraces. River terraces are the crucial geomorphologic elements used to reveal the environmental information in study areas. With the development of the meterage instruments, the date - measure technology will be more accurate and sensitive. The dynamic simulation and the quantitative analysis for the formation and evolution of river terraces need more exploration.

Key words: causes of formation, climate change, environment responses, river terrace, tectonic processes
