According to the data of observed points in Zhuanyaogou watershed in the typical gully region of the loess plateau
spatial distribution characteristics of soil total carbon(STC) content were discussed by geo-statistical approach.The reserve of STC was calculated by modeling on the base of the spatial distribution maps of STC in the watershed made by Kriging.The results indicated that the STC content decreased with the increase of depth.At the same depth
the STC contents were highest on the tops of the hills and were lowest in the gullies.The reserve of STC in the range of 0—100 cm was 51.8% of that in the range 0—200 cm depth in the watershed.The STC storage in the depth of 100—200 cm is important for predicting the total STC reserve in the area of Loess(Plateau.)
