河流阶地研究进展综述

摘要

河流阶地是地貌学研究的热点问题之一，其在研究新构造运动、古气候变化、古水系演化以及侵蚀基准面变化等方面具有不可替代的优势。近年来，随着宇生核素测年、计算机模拟等先进技术手段相继应用到河流阶地研究中，河流阶地研究在年代学、发育模式、指示水系演化以及数值模拟等方面取得了显著进展，并将在精确测年应用和数值模拟研究上进一步深入。%River terrace, which is one of the hot issues of the study on river geomorphology, has irreplaceable advantages in the studies on neotectonic movement, paleoclimate change, evolution of palaeo-drainage system and erosion base level change. In recent years, along with cosmogenic radionuclide dating and computer simulation applied to the study of river terraces, the researches on river terraces have gained signiifcant progresses in the chronology, development model, indicating evolution of drainage system and numerical simulation, and will strengthen the precise dating application and numerical simulation of the river terrace research in the future.
