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。The new era began ; the king was tried, doomed, and beheaded ; the republic of liberty, equality, fraternity, or death, declared for victory or death against the world in arms ; the black flag waved night and day from the great towers of notre dame ; three hundred thousand men, summoned to rise against the tyrants of the earth, rose from all the varying soils of france, as if the dragon s teeth had been sown broadcast, and had yielded fruit equally on hill and plain, on rock, in gravel, and alluvial mud, under the bright sky of the south and under the clouds of the north, in fell and forest, in the vineyards and the olive - grounds and among the cropped grass and the stubble of the corn, along the fruitful banks of the broad rivers, and in the sand of the sea - shore
三十萬人的大軍為抗擊全世界的暴君響應號召從法蘭西各地猛然崛起,彷彿田野上遍撒了,結滿了果實:從山上也從平原上從巖石上,也從碎石上和沖積土壤上在南方明朗的天空之下,也在北方積雲的天空之下從丘陵里,也從森林里從葡萄園,也從橄欖地在剪過的草地上,也在氣過的莊稼地上沿著廣闊的河流的結著果實的河岸,也沿著海岸的沙灘,到處都結出了的果實。Meanwhile, most aspects about this perspective are concerned, which include quantification of the soil water background of the plateau area, the regional spatial variation of soil water background and variation along the slope, mosaic structure and seasonal changes etc. the results show that : ( 1 ) for the fundamental circumstance for vegetation development is the original debilitated slope, so the perspective of soil water background specially for the loess plateau refers to the soil water conditions on the original slope. ( 2 ) the value of soil water background appears to be a descending trend from south to north based on the difference of vegetation zones. in the forest zone, soil moisture contents beneath 3m depth from the soil surface are more than 12 % usually ; in the forest - pasture zone, the values of soil moisture content beneath 4m depth underground are more than 6 % and stable, and tend to be ascending while the depth increases ; but the values in the dry pasture zone is lingering between 4 % to 6 % from the surface layer to sub - layers
發展了「土壤水分背景」的概念,並以之為基礎對其各個方面進行了研究,使之形成一個相對獨立和完整的體系,主要包括黃土高原土壤水分的背景值、土壤水分背景的區域分異、坡面分異、鑲嵌結構及其季節分異等: ( 1 )由於植被生長發展、演替的基礎階段是天然草被群落,故認為黃土高原的土壤水分背景在概念上是特指該區天然草被群落下的土壤水分狀況; ( 2 )黃土高原的土壤水分背景值,根據植被地帶的不同表現出自南向北逐漸降低的規律:森林地帶3米以下土層水分背景值普遍穩定地高於12 ,森林草原地帶4米以下土層水分背景值穩定大於6 ,且均隨土層的加深水分含量逐漸增加,而草原帶的土壤水分背景值自土表至底土層一直在4 6之間徘徊。The north slope on the east part of qilian mountains was separated into 6 vertical distribution zones : alpine cold desert meadow 、 alpine meadow 、 alpine bush meadow 、 mountain forest grassland 、 mountain grassland 、 and mountain desert grassland, there are also some areas of alternative distribution
