They are jinfo mountain in nanchuan county ( natural protection section ), wuling mountain in qianjiang county ( national emphases forest demonstration county which forest cover rate is beyond 50 % ) and zhongliang mountain in beibei county ( artificial destruction is very grave ). some main land use patterns i. e. woodland, garden, infield, abandon infield, shrub and grassplot are selected in those three sample sites. four aspects on soil fertility index of karst environment under different land use patterns in these three sample sites, are revealed in this paper, by using the field test, indoor measure and analysis, outdoor experiment and field investigation, and the knowledge and technique of soil, ecology, physics and chemistry etc. they are physical characteristic ( effective soil thickness, organic layer thickness, soil texture, water - stable aggregate and soil water etc. ), chemical fertility ( organism, omni - n, omni - p, omni - k, alkali - nitrogen, available p, available k and rapid available k etc. ), soil animalcule ( bacteria, fungi, actinomyces and their grosses ) and soil - seed - pool ( plant community diversity index ) in karst ecosystem
本研究以重慶市的南川金佛山(自然保護區) 、黔江武陵山(國家重點退耕還林示範縣,森林覆蓋率50以上)和北碚中梁山(遭人為破壞嚴重)典型巖溶區為對象,選擇了幾種重要的利用方式,包括林地、果園、耕地、棄耕地和灌草坡,採用野外巖溶生態調查和室內試驗測量分析相結合的方法,以不同土地利用方式巖溶土壤肥力為重點,對不同土地利用方式土壤肥力特徵進行量化分析,找出巖溶土壤肥力差異的主要方面及其根本原因,論文主要從土壤剖面物理退化指標(有效土層厚度、有機質層厚度、質地、團聚體、水分含量等) ,化學肥力退化指標(有機質、全n 、全p 、全k 、堿解n 、速效p和速效k等) ,樣地土壤微生物指標(細菌、真菌、放線菌數量及總量)以及樣地土壤種子庫植物群落多樣性等4個方面對重慶典型巖溶區的土壤肥力特徵進行了較為詳細的分析研究,為巖溶地區士壤資源的合理利用及結構的調控管理提供依據。But so far, there have not report about forest soil microbe and soil enzymatic activity in westen sichuan. the study ' s object is bitch forest. spruce forest, fir forest, chrysanthemum alp, willow community and two couch grass, so the research of the soil microorganisma, soil enzymatic activity in the subalpine coniferous forests in western sichuan is significant to china. the result shows that : 1. in the soil, the relativity of the soil microbial puantity is very prominence, the relation with the quantity of the soil microorganism is that : bacillus > actinomyceto > fungi ; the amount of the microorganism of physiological group sequence ranging from high to low is : aminate > bacteriumazotobacter > denitrify bacterium > nitrobacteria > cellulose decomposing bacteria. under the different vegetable community, the microbial quantity is that : s5 > s7 > s6 > s1 > s2 > s4 > s3
其中,各群落中土壤微生物總數以白樺純林( s5 )群落最多,每克干土中的含菌量達66 . 13 10 ~ 6個;其次是冷杉針葉林( s7 )群落,每克干土中的含菌量達43 . 41 10 ~ 6個:第三是雲杉針葉林( s6 )群落,每克干土中的含菌量達42 . 85 10 ~ 6個;第四是繡線菊-茅草群落( s1 ) ,每克干土中的含菌量達33 . 83 10 ~ 6個;第五是高山柳群落( s2 ) 、茅草( s4 )群落,每克干土中的含菌量分別為33 . 33 10 ~ 6個和33 . 08 10 ~ 6個;第六是茅草群落( s3 ) ,土壤微生物數量最少每克干土中的含菌量僅為23 . 12 10 ~ 6個。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。Leachate. detecton of total bacteria number. plate count for bacteria colonies
