黄土高原历史地貌与土壤侵蚀演变研究进展

黄土高原是引人注目的生态环境脆弱区,它的历史地貌与土壤侵蚀演变研究是其历史时期生态环境变迁研究的重要内容,也是黄土高原生态环境建设的基础性课题.回顾了黄土高原历史地貌与土壤侵蚀演变研究的过程,总结了研究取得的主要进展,指出了研究存在的不足和今后深化的方向.经过数十年的积累,黄土高原历史地貌与土壤侵蚀演变研究取得了重要的进展:较深入地研究了历史时期黄土塬区地貌演变的特征和规律,揭示了历史时期渭河河谷地貌的演变,研究了历史时期黄河中游的河道变迁,提出了黄土高原的侵蚀期,得出了历史时期黄土高原的土壤侵蚀历史、侵蚀速率.今后的研究应应用现代研究手段,以长时段、短周期、高分辨的研究为研究深化的方向.

Progress on the research of historical landform and soil erosion evolution in Loess Plateau

Loess Plateau is noticeable for its fragile zoology, and it is very vulnerable.This paper reviews the studying process on historical landform and soil erosion evolution of Loess Plateau, summarizes its essential results, points out the inadequate and the deepen direction in the future. By reviewing the research, the paper summarizes its progress such as thoroughly studies of the features and laws of landform changes of Loess Yuan region; the Weihe River bed changes process; Huanghe River middle reaches course changes, erosion period of Loess Plateau, soil erosion records and erosion speed of Loess Plateau during human history. In the future, modern methods shall be introduced to this study in order to receive long time, short period and higher distinguish results.
