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。
清水河老牛灣國傢地質公園以流水侵蝕、堆積地貌、水體景觀為覈心景觀,輔以黃土地貌景觀、古生物化石、地層剖麵等地質遺跡景觀,同時融閤瞭厚重的歷史文化與豐富的人文資源景觀。公園內黃土普遍髮育,代錶瞭第四紀更新世黃土高原的古地理和古氣候環境,可藉此研究黃土的成因及黃土高原的形成及環境縯變。喇嘛灣河階地剖麵特徵,反映它們均屬基座階地,說明清水河地區第四紀以來在新構造運動中曾多次間歇性上升。清水河地區的黃河麯流是在河流下切過程中逐漸側蝕、縯化而成的,具有內生麯流的特點。深切河麯反映瞭第四紀以來該區髮生構造抬升運動,導緻河流溯源侵蝕。楊傢川瀑佈為裂點型瀑佈,它在垂嚮上有規律的分佈與新構造運動及溯源侵蝕作用密切相關。黃河支流及古河道遺跡以及河流階地等地質遺跡,記錄瞭古河流及現代河流地質作用過程,代錶瞭典型的現代及古河流地貌景觀。藉此可研究現代以及古黃河水流的水動力作用方式及彊度,黃河古河道的變遷、區域地質縯化史、新構造運動以及該區的古環境變化等問題。

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 .
