Abstract: Based on field investigation and experimental data,the effects of soil and water conservation from different models of conversion of farmland to forest,were as follows:mixture of picea crassifolia and birch>birch>mixture of picea crassifolia and hippophae rhamnoides>picea crassifolia >hippophae rhamnoides>farmland,in hilly loess plateau in Qinghai province. The effects of biodiversity were as follows: mixture of picea crassifolia and birch >hippophae rhamnoides>birch>picea crassifolia >mixture of picea crassifolia and hippophae rhamnoides>farmland. The effects of microclimate were as follows:mixture of picea crassifolia and birch>birch>mixture of picea crassifolia and hippophae rhamnoides>hippophae rhamnoides>picea crassifolia>farmland. The study also showed the ecological effects were increasingly better as forest age increased.

Key words: hilly loess plateau, models of conversion of farmland to forest, ecological effects, biomass
