Abstract:: This paper selected 4 different slope catchment measures (organic silicon, bare and smooth, lichen and grass slope), and discussed the effect of slope catchment project on catchment rainfall amount and catchment rainfall efficiency, and on stand growth either.This paper aimed at offering the basic theoretic foundation for the Loess Plateau ecological construction and drought resistant and water saving forestation scheme.The results show that: the maximum of catchment rainfall amount and catchment rainfall efficiency is organic silicon surface, next order is concret surface, lichen surface, bare and smooth surface and grass slope surface; but, on the considering of ecological, bare and smooth surface is the best; bare and smooth surface and lichensurface can accelerate the forest growth than that of the common surface, and the lichen surface have more effect than the bare and smooth surface.This paper chose 4 efficiencies of Robinia pseudoacacia under 6 stand density including water use efficiency, rainfall production efficiency, evapotranspiration water production efficiency and transpiration water production efficiency.With the decreasing of stand density of Robinia pseudoacacia, all the four efficiencies have been improved.
