Based on the experimental data for 4 years

the harness and utilization of various exposed gneiss slope land are discussed

and the suitable kinds of trees and the gully reclamation in the area which exposed slope land of gneiss is distributed widely are also discussed. The results show: The condition which is suitable to the growth of trees on the exposed slope land of biotite-amphibole-plagioclase-gneiss is the best of all

so it is suitable to develop the economic trees. The condition of exposed slop land of granite-gneiss is better

it can be used for soil and water conservation trees.The conditions of exposed slope land of gneiss-syenite is the worst of all

it can not be utilized directly

and should be set apart mountains for afforestation. Besides

the effect of the protection dam along the both sides of gullies is better than the sand-control dam across gullies in the gully reclamation.
