Abstract:: The changing dynamics of soil moisure were studied,on the returning farmland to forest ecosystem in the loess hilly-gully region.It showed that,the soil moisure increased at first and then reached a plateau under the condition of nature recovery with the vegetation restoration years growth.It owns much water in topsoil layer,soil moisure is 4% in the deepth of 200 cm,close to wilting coefficient,and then stabilized under the 300cm deepth,about 9%～12%,of the artificially accelerated ecological restoration.There was a serious deficiency of deep soil moisure in the sunny slope,and the shady slope is better than sunny slope when the years of returning farmland to forest ecosystem over 40 years.In contrast,the effect of artificial accelerated ecological restoration is obviously in the early years,then the nature restoration hold advantage with the increase years.
