Mongolica young stand, secondary natural forest, and the mixed forest of larix olgensis and fraxinus mandshurica rupr. countermeasures for controlling soil degradation were also recommended. the study got following results : ( 1 ) from young stand to mid - age of larix olgensis, with the closure of canopy and the decrease of undergrowth vegetation cover, soil acidity, enzyme activity, total inorganic phosphorus, available k, soil moisture and total porosity decreased significantly ; while soil organic matter content, humus component content, the amount of three main types of microbes, acid phosphatase activity, and bulk density in rhizosphere soil and non - rhizosphere soil increased with the increase of the amount of forest floor litter ; from mid - age stand to near mature stand, with the decrease of stand density and crown cover as well as the restoration of undergrowth vegetation after preliminary thinning, soil organic matter content, fulvic acid, exchangeable acidity, exchangeable aluminium, neutral phosphatase activity, total amount of inorganic phosphorus, the amount of actinomycetes, soil moisture, and total porosity in rhizosphere soil and non - rhizosphere soil apparently increased ; from near matu re stand to mature stand, soil activity acidity, organic matter content, humus component content, available phosphorus, total amount of amino acid, available k, soil enzyme activity, soil moisture, and total porosity in rhizosphere soil and non - rhizosphere soil decreased, but total phosphorus, soil acidity ( in particular, exchangeable aluminium ), and bulk density increased
結果表明： （ 1 ）從落葉松幼齡林到中齡林，隨著林
冠的郁閉和林下植被蓋度的急劇下降，林地土壤酸度、土壤酶活性、無機磷總量、速效鉀、土壤水分含量、總孔隙度呈明顯下降趨勢，而根際和非根際土壤有機質含量、腐殖質各組分含量、三大類微生物數量、酸性磷酸酶活性和土壤容重隨著凋落物的增加呈明顯上升趨勢；從中齡林到近熟林，由於撫育間伐，林分密度及郁閉度下降，林下植被蓋度逐步得到恢復，根際與非根際土壤有機質含量、富里酸、交換性酸、交換性
鋁、中性磷酸酶、無機磷總量、放線菌數量、土壤水分含量、總孔隙度呈明顯的上升趨勢；從近熟林到成熟林，隨著林齡的增大，根際與非根際土壤活性酸、有機質含量、腐殖質各組分含量、有效磷含量、氨基酸總量、速效鉀、土壤酶的活性、土壤水分含量和總孔隙度呈下降趨勢，而根際與非根際土壤全磷含量、土壤酸度（特別是交換性
鋁）和容重呈增加趨勢。
