巖溶含水層
英文
karst aquifer-
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。By infrared spectrum study, the limonite ( feooh nh2o ) can be considered the main colorating mineral in the yellow and red jadeite, and the hematite is another colorating mineral in the red jadeite. the difference of color tone is due to the n value in the molecular formula feooh nh2o and the content of crystal water and adsorbent water. the iron ion came from the effloresced and eroded rocks, and formed fe ( oh ) 3 colloid reacted with the surface water
周圍礦床的風化蝕變為表生水提供了鐵質,形成弱酸性的含fe ( oh ) _ 3膠體的水溶液,表生水流經翡翠礦石時, fe ( oh ) _ 3膠體附著在巖石的表面,經過脫水結晶和吸附,形成褐鐵礦膠體,褐鐵礦膠體沿裂隙或鬆散的礦物顆粒進入翡翠巖石中,逐漸累積沉澱,形成次生色層。The high content and the high water temperature favour the solution of salt and metals from the underground formations.
高含量和高水溫促進了地下巖層里鹽類和金屬的溶解。The acidic liquid related to decomposition of organic mater during hydrocarbon enrichment in the late diagenesis, and m eteoric - waters during epidiagenesis, had resulted in dissolution of detrital feldspars and carbonate cements, which contributed a better retention of reservoir quality for the sandstones
溶蝕作用是砂巖物性改善的主要原因,尤其是晚期成巖階段,在富含有機酸和無機酸酸性孔隙流體的作用下形成一定量的次生溶蝕孔,使儲層砂巖物性得到一定改善;在表生成巖階段,由於大氣降水的介入,儲層物性再次得以改善。Vulnerability of karst aquifers in houzhai river basin and its relations with landuse change
后寨河流域巖溶含水層脆弱性及其對土地利用方式的響應The lay - like karst aquifer formed by some special strata and fossil karst are very important in the groundwater exploitation in this area
