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。With respect to protective forests such as those for water supply conservation, water and soil conservation, windbreak and sand - - fixation, felling shall only be permitted for tending and regeneration of forests
對水源涵養林、水土保持林、防風固沙林等防護林只準進行撫育和更新性質的採伐。In cradle while cut down divides low - grade forest, notice to do authority of nice area branch and low layer vegetation clear the job, can reduce rat already kind concealment place, destroy mouse kind live condition, reduce rat kind density, can reduce miscellaneous bush to wait again at the same time right young forest competition, those who be helpful for forest is hale grow and shift to an earlier date closing cheng lin, the forest land after yu ren is shut goes against rat kind habitat, can rise to control rat to feel the effect that produces greatly
在撫育伐除劣等林木的同時，注重做好地面枝權及低層植被的清理工作，既可減少鼠類的隱蔽場所，破壞鼠類生存條件、降低鼠類密度，同時又能減少雜灌木等對幼林的競爭，有利於林木的健壯生長和提前郁閉成林，郁人閉后的林地不利於鼠類棲息，可以起到控制鼠害大發生的作用。Evergreen broad - leavedforest is classified into three types as follows : nurture type of early sapling forest, intemediate cutting type of medium sapling forest, density management type of mid - maturation forest
將闊葉林劃分為3個經營類型，分別為:初期幼齡林組成撫育類型、中期幼齡林撫育間伐類型、中齡林密度管理類型。Strengthen young forest cradle management, strict according to cradle cut regulations, fixed rotate carries out exercise
