| Abstract: | The optimum structure of the protection forest system in Small Valley on Loess Plateau Gully
Area were analysized by AHP.The result indicated that the protection forest in the steep barren
slope are 27.4%,18.8% in the very steep barren slope,15.0% in the top of gully,13.8% in the top
of barren hill,12.6% in the lwo-land of gully,6.2% in the edge of terraced fields,6.2% in the edge
of gully.\=\ \ |
