黄土高原（英文：Loess Plateau 亦作Huang-t'u Kao-yuan或Huangtu Gaoyuan） 世界最大的黄土高原。在中国中部偏北，包括太行山以西、秦岭以北、乌鞘岭以东、长城以南的广大地区。跨山西、陕西、甘肃、青海、宁夏及河南等省区，面积约40万平方公里，海拔1500到2000。除少数石质山地外，高原上覆盖深厚的黄土层，黄土厚度在50∼80公尺之间，最厚达150∼180公尺。黄土颗粒细，土质松软，含有丰富的矿物质养分，利于耕作，盆地和河谷农垦历史悠久，是中国古代文化的摇篮。但由于缺乏植被保护，加以夏雨集中，且多暴雨，在长期流水侵蚀下地面被分割得非常破碎，形成沟壑交错其间的塬、墚、峁。 在中国北方,它东起太行山，西至乌鞘岭，南连秦岭，北抵长城,主要包括山西、陕西、以及甘肃、青海、宁夏、河南等省部分地区,面积40万平黄河流过黄土高原方公里占世界黄土分布70％,为世界最大的黄土堆积区。黄土厚50—80米,气候较干旱,降水集中,植被稀疏,水土流失严重。黄土高原矿产丰富,煤、石油、铝土储量大。 平坦耕地一般不到1/10,绝大部分耕地分布在10°∼35°的斜坡上。地块狭小分散，不利於水利化和机械化。水土流失严重。黄河每年经陕县下泄的泥沙约16亿吨，其中90％来自黄土高原，随泥沙流失的氮磷钾养分约3,000余万吨。综合治理黄土高原是中国改造自然工程中的重点项目，治理方针是以水土保持为中心，改土与治水相结合，治坡与治沟相结合，工程措施与生物措施相结合，实行农林牧综合发展，这种治理措施已取得重大成绩。黄土高原地区蕴藏著丰富的煤炭、石油、铝土矿等资源，是中国重要的能源、化工基地。 地貌类型 是指平坦的黄土高原地面，著名的有甘肃东部的董志塬，陕西北部的洛川塬。塬面宽阔，适于机械化耕作，是重要的农业区。但是塬易受流水侵蚀，沟谷发育，分割出长条状塬地，成为山梁，称为“梁”地。如果梁地再被沟谷切割分散孤立，形状有如馒头状的山丘，当地称为“峁”。由“梁”和“峁”组成的黄土丘陵，高出附近沟底大都在100～200米左右，水土流失严重，是黄河泥沙来源区。川是深切在塬面下的河谷平原。在梁峁地区地下水出露，汇成小河、河水带来的泥沙在这里沉积，在两岸形成小片平原，称它为“川”。川两旁还有阶地，即“掌”、“杖”地。掌是川地上源的盆地状平原，与条状分布的杖地不同。 黄河在它的中、上游流经世界上最大的黄土高原。黄土高原土层深厚，土质疏松，地形破碎，暴雨集中且雨量大，水土流失极为严重，是黄河泥沙的主要来源地。尤其是黄河河口镇至潼关这一河段，黄河在穿越这一段黄土高原的过程中，众多支流汇入，把黄河“染成”了黄色。据测定，这一河段进入黄河的泥沙占全河沙量的90%。 基本分类 根据地貌的形成过程和特点，可分为以下几个部分： ①陇中高原。一称陇西高原。位于六盘山以西，是一个新生代的拗陷盆地，属盆地型高原，海拔1500～2000米。地形破碎，多梁、峁、沟谷、垄板地形。 ②陇东、陕北高原。包括六盘山以东，吕梁山以西，渭河北山以北，长城以南的地区。也是一个盆地型高原，海拔800～1200米。经强烈侵蚀，除少数残留的黄土塬（董志塬、洛川塬）外，大部地区已成为破碎的梁峁丘陵。其间只有少数基岩低山突起在高原之上，状似孤岛。 ③山西高原。包括五台山、恒山以南，伏牛山以北，太行山以西，吕梁山以东的地区。它由一系列褶皱断块山与陷落盆地组成。山地有吕梁、恒山、五台、中条及太行等山，盆地有大同、忻县、太原、临汾、运城等。除河谷平原外，大部地区海拔在1000～1500米，石质山地构成高原的主体，黄土堆积仅限于盆地及山间谷地，分布范围约占全区面积的40％。 ④渭河平原，一称关中平原。位于渭河北山与秦岭之间，西起宝鸡。 气候特点 温带大陆性气候；气温年较差、日较差大，降水稀少；温带季风气候;夏季高温多雨,冬季寒冷干燥。
