Most loess is considered to be an eolian deposit . 大多數(shù)黃土被認(rèn)為是一種風(fēng)成沉積。
Wind-deposited sediment called loess occurs in many places . 被稱為黃土的風(fēng)成沉積物,在許多地區(qū)均有。
There the soil is from weathered limestone soil or loess . 那里的土壤是經(jīng)過風(fēng)化作用的石灰石土壤或黃土。
Loess is easy borne by the wind and may be carried long distances before it falls to earth and becomes topsoil . 黃土易被風(fēng)刮起并帶至遠(yuǎn)處方才落下成為表土層。
When rain falls, the loess particles on the surface layer swell and form a crust that is almost impermeable to water . 降雨時(shí),表層的黃土粒就發(fā)生膨脹并形成一層幾乎是不透水的表皮。
Located to the south of china 's inner-mongolia plateau is the world 's largest loess plateau , traversing the entire territory of shanxi province , part of shaanxi and gansu provinces , and the ningxia hui nationality autonomous region. it covers an area of approximately 600,000 square kilometers and rises 1,000 to 2,000 meters above the sea level . 世界最大的黃土高原,位于中國(guó)內(nèi)蒙古高原以南,包括山西省全部和陜西、甘肅、寧夏回族自治區(qū)的一部分,面積約60萬平方公里,海拔在1000至2000米。
