Abstract:: The law of growth response of Panicum virgatum L.in different locations of the Loess Plateau was conducted.The soil water content showed a significant increase named as sloping field (13.39%)P.virgatum.A close relationship was discovered in soil moisture, root biomass and soil depth.In the above sites mentioned the plant height, cover rate, the biomass, weed and the plant debris of Panicum virgatum L.exhibited a distinct response to the location characteristic, among which the height and coverage declined orderly with the plain to sloping field to terrace.However, as well as surrounding weed biomass and the debris, the above-ground biomass of P.virgatum in the plain acquired a greater amount compared that in terrace and sloping field.In addition, the content of organic matter and nitrogen element in the grown soil showed a closely positive relationship with the productivity establishment of P.virgatum.Therefore P.virgatum could grow well in different habitats in the loess hilly regions because of its wide adaptability.Therefore the variation of water content and fertilizer in soil determined the growth response of P.virgatum on hilly regions of the Loess Plateau.
