The Loess Plateau ,is the only accumulated plateau in the world. It is composed of hundred meters of loess, which is accumulated during the whole Quaternary and even in the Pliocene. The unique properties of loess, such as, homogeneously fine grain size, high porosity, and its softness, make it easy to plough and subject to erosion. The development of gully system produces diversity of loess landforms. But the heavy soil erosion has a great impact on the daily life of the local people. The basement of the Loess Plateau is Mesozoic and Tertiary basins. The red clay, found beneath loess layers and above bedrock, is called Hipparion Clay and is correlated with Pontian.
