Abstract: The ecological effects of ecological forest,economic forest and shrubbery in the project of conversion of cropland to forest of Hebei,Liaoning,Hubei,Hunan,Yunnan and Gansu provinces were assessed by using the distributed measurement method.The results show that the total ecological effect of ecological forest is the best,followed by that of forest and shrubbery which is the worst.The effect of ecological forest is the best for carbon fixation and oxygen release,nutrient accumulation,atmosphere environmental purification and biodiversity protection. The effect of shrubbery is the best for soil conservation. The effect of ecological forest is better than that of shrubbery for water conservation.

Key words: the project of conversion of cropland to forest, ecological forest, economic forest, shrubbery, ecological effects
