摘 要:清水河老牛湾国家地质公园以流水侵蚀、堆积地貌、水体景观为核心景观,辅以黄土地貌景观、古生物化石、地层剖面等地质遗迹景观,同时融合了厚重的历史文化与丰富的人文资源景观。公园内黄土普遍发育,代表了第四纪更新世黄土高原的古地理和古气候环境,可借此研究黄土的成因及黄土高原的形成及环境演变。喇嘛湾河阶地剖面特征,反映它们均属基座阶地,说明清水河地区第四纪以来在新构造运动中曾多次间歇性上升。清水河地区的黄河曲流是在河流下切过程中逐渐侧蚀、演化而成的,具有内生曲流的特点。深切河曲反映了第四纪以来该区发生构造抬升运动,导致河流溯源侵蚀。杨家川瀑布为裂点型瀑布,它在垂向上有规律的分布与新构造运动及溯源侵蚀作用密切相关。黄河支流及古河道遗迹以及河流阶地等地质遗迹,记录了古河流及现代河流地质作用过程,代表了典型的现代及古河流地貌景观。借此可研究现代以及古黄河水流的水动力作用方式及强度,黄河古河道的变迁、区域地质演化史、新构造运动以及该区的古环境变化等问题。Laoniuwan National Geopark,Qingshuihe County from Inner Mongolia features water erosion,accumulation landforms,water landscape as the core scenery,supplemented by loess landscape,fossils,the stratigraphic section and other geological heritage landscape,completed with a blend of profound and rich history and culture human resources landscape.The common development of loess in the park represents the ancient geography and the ancient climate environment of the Quaternary Pleistocene loess plateau,and can study the genesis of loess and the formation of Loess Plateau and the environment evolution.According to characteristics of Lama Bay terrace profile diagram,reflecting that they belong to the base terrace,pointing out in Qingshuihe area since Quaternary in new tectonic movement has repeatedly intermittent rise.Qingshui River area of the Yellow River meandering is in the river cutting in the process of gradually lateral erosion,evolution and,with endogenous meandering characteristics.Deep Hequ reflects the tectonic uplift movement since the Quaternary,resulting in the erosion of the source of the river.The genesis of the Yang Jiachuan falls is a crack type waterfall.This type of waterfall is closely related to the vertical distribution of the vertical and the new tectonic movement and the erosion of the source.Geological relic in the tributaries of the Yellow River and river ancient ruins and river terraces,represents a typical modern and ancient river landscape,modern research and ancient Yellow River flow hydrodynamic mode of action and strength,the changes of ancient river course of the Yellow River,the regional geological evolution history,new tectonic movement and the pale environmental change.
