The relationship between changes of history and the present condition of forest and grasslands and the loss of soil and water on the Loess Plateau is comprehensively studied first in the paper

based on physical properties (e.g.soil infiltration and anti-scouringbility) in the cultivated and forest soils

The study results show that the plough sole resulted from agriculturally protracted cultivation is the main cause of increasing loss of soil and water on the Loess Plateau.Speeding up the renew of vegetation in the region is the only effective approach of all precipitation inFiltrating on the spot and brings the Huanghe River under the permanent control.
