Restoration of vegetation and soil nutrients on the northern area of Loess Plateau
Introduction Severe loss of soil and water quality has occurred on the northern area of the Loess Plateau.Past research showed that 80％ of the mud and sand streamed into the Yellow river came from the northern area of the Loess plateau,and most of the mud and sand came from sloping fields (Wei,T.X.2002).Since the grain-for-green policy was implemented,not only has the expansion of sloping fields been controlled,but also the restoration of vegetation was facilitated.So far,most research has reported on the effect of returning sloping fields into woodlands and grasslands on water and soil conservation,but little research has been conducted on vegetation restoration and soil nutrients.In this research,Shenmu County in Shanxi province,located in the north of Loess Plateau,was chosen as the survey area.We analyzed the effect of returning sloping fields into woodlands and grasslands on restoration of vegetation and soil nutrients.The research results are expected to supply a scientific basis for ecosystem restoration.
