一、內(nèi)容

???黃土高原(the Loess Plateau)是中國(guó)第三大高原,面積約60萬(wàn)平方公里,平均海拔1000-2000米，絕大部分覆蓋著50-80米厚的黃土，是世界上黃土分布最集中、覆蓋厚度最大的區(qū)域。這是大自然創(chuàng)造的一個(gè)奇跡，在世界上也是絕無(wú)僅有的。黃土高原是中華民族的發(fā)祥地之一。早在5500年前,人們就已經(jīng)在黃土高原上開(kāi)始農(nóng)耕。隨著農(nóng)耕業(yè)的持續(xù)發(fā)展,黃土高原人口不斷增加,在秦漢時(shí)期就成為中國(guó)的政治和經(jīng)濟(jì)中心，如今，隨著西部大開(kāi)發(fā)戰(zhàn)略的實(shí)施,黃土高原地區(qū)的經(jīng)濟(jì)得到了迅速發(fā)展。
