为明确郑州地区晚更新世晚期以来的沉积环境与气候变化趋势，通过综合分析郑州西部嵩山山前的ZK05钻孔沉积物的粒度变化情况，在精确测年框架基础上，对晚更新世晚期（18 ka）以来的沉积环境和气候变化进行了分析。分析得出：18 ~ 14.9 ka（第一阶段）该时期ZK05钻孔沉积环境为边滩沉积，气候寒冷干旱；14.9 ~ 6.38 ka（第二阶段）该时期河流水动力明显减少，沉积环境为河漫滩沉积，气候逐渐变暖湿；6.38 ~ 2.73 ka（第三阶段）该时期较上一阶段，水动力减少明显，沉积环境为河漫滩沉积，气候温暖湿润；2.73 ka以来（第四阶段）该时期沉积环境为河床相，水动力明显增强，气候温暖湿润。通过粒度和年代学分析，为该区域沉积环境演化和气候变化研究奠定了基础。

To clarify the sedimentary environment and climate change trends in Zhengzhou area since the late Late Pleistocene, by comprehensively analyzing the grain size changes of the sediments in the ZK05 borehole in front of Songshan Mountain in the west of Zhengzhou, and based on the precise dating framework, the sedimentary environment and climate changes since the late Late Pleistocene (18 ka) were analyzed. Analysis shows that the sedimentary environment of ZK05 borehole during the period of 18 ~ 14.9 ka (first stage) was beach sedimentation, with a cold and arid climate. During the second stagethis period(14.9 ~ 6.38 ka), the river water dynamics significantly decreased, and the sedimentary environment was floodplain sedimentation, with the climate gradually becoming warm and humid. During the third stage period(6.38 ~ 2.73 ka), the hydrodynamic force decreased significantly compared to the previous stage, and the sedimentary environment was floodplain sedimentation, the climate is warm and humid. Since the fourth stage(2.73 ka), the sedimentary environment during this period has been riverbed facies, with significantly enhanced hydrodynamics and a warm and humid climate. Through granularity and chronological analysis, a foundation has been laid for the study of sedimentary environment evolution and climate change in the region.
