Abstract: A proposal concerning that closed forage herbs and shrubs in the desert areas should be used by grazing was put forward according to the observations at fixed site and investigations.Of all using ways,the grazing is optimum way.The closed regings where utilization is totally prohibited have been a tremendous waste of the vegetation resources in the desert areas.The functions of the closing and the desert ecosystems will not be disturbed so long as the grazing is reasonable.On the contray,the reasonable utilization by grazing is conducibe to the control of desertification and over-grazing of other regions because of the rducing of the pressure upon the non-closed desert rangelands,and also promoting the development of the livestock husbandry in the desert areas,increasing the growth of the plants in the exclosures,enabling the closing more effective and maintaining the ecological equilibrium.The utlization of the closed forage herbs and shrubs must be reasonable and rational.
