成熟林分-
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。 -
He is always wrestling in prayer for you, that you may stand firm in all the will of god, mature and fully assured
他在禱告之間、常為你們竭力的祈求、願你們在神一切的旨意上、得以完全、信心充足、能站立得穩。 -
Based on above - mentioned analysis, the strategy and measures to prevent the soil fertility quality degradation of artificial picea mature forest and improve the stand ecological environment were put forward, including the rational management of inter - cutting down and fostering after artificial picea forest matured. because conifer - hardwood forests generally contain more tree species than pure coniferous forest, and their structure also is more complex, forestation in subalpine of western sichuan should be conifer - hardwood forests
林地土壤有機質主要來源於凋落物的分解，並受其分解速率的控制，解決當前人工成熟林地土壤退化的主要措施應為林地凋落物分解創造條件，即因地制宜地對成熟人工林進行間伐或輪伐，當前在該區域造林應避免營造針葉純林。 -
Col. 4 : 12 epaphras, who is one of you, a slave of christ jesus, greets you, always struggling on your behalf in his prayers that you may stand mature and fully assured in all the will of god
西四12有你們那裡的人，作基督耶穌奴僕的以巴弗問你們安；他在禱告中常為你們竭力奮斗，要你們得以成熟，站立得住，在神一切的旨意上滿有確信。 -

The reduction of soil nutrient content and enzyme activity, and the apparent increase of soil acidity and bulk density are likely the main reason for soil degradation in mature stand
土壤養分和酶活性的降低以及土壤酸度和容重的顯著增加是成熟林土壤質量降低的主要原因。
