    Abstract:

    On the basis of investigation and analysis in field,soil bulk weight,soil organic matter and quick effect nutrient were measured in apricot and peach bush forest in different rebuild ways.The result shows the content of organic matter and nitrogen are obviously increasing in hillland soil which are through artificial hillside rebuilt engineering,the incensement of organic matter and nitrogen content increasing are higher than others,but the soil quick result potassium has small increasement in forestry root active layer of 40—60 cm deepth.
