河南黄土研究进展

Research Progress of Loess Study in Henan Province

黄土是记录新生代晚期以来全球自然环境和气候变化的最好载体。河南黄土位于黄土高原与华北平原过渡带,是中华民族和华夏文明的重要发祥地,其特殊的地理位置详实地记录了区域古气候短周期的演替旋回。首先,结合我国西北地区的黄土研究,对河南黄土发育的研究现状和问题进行剖析;然后,阐述了河南地区黄土分布及其地貌类型、黄土地层的划分、全新世黄土的研究以及黄土与考古文化研究两者之间的关系4个热点研究领域的研究进展;最后,对河南地区黄土研究过程中所存在的问题作了归纳与总结。

Loess is the best record carrier of global natural environment and climate change since the late Cenozoic.Henan loess,located in the transition zone between the Loess Plateau and the North China Plain,is an important birthplace of the Chinese nation and the Chinese civilization.It was able to record the regional cycles of paleoclimate short cycles in more detail because of the special geographical location.This paper analyzes the research status quo and problems of Henan loess development combined with the loess study of the Loess Plateau in the northwest China.It describes the research progress of three current research focus division of loess distribution and landform type in Henan area,along with the classification of loess strata and research on Holocene Loess.Furthermore,the relationship between the research of loess development and archaeological culture is discussed.Finally,the paper summarized the problems existing in the research process of loess in Henan Province.
