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。Sample ' s analyses and tests in laboratory, this thesis makes a detailed research on holocene deposits characteristics of mu us desert, especially on characteristics of grain size composition, which break through previous description of determining the nature and gain a series of number indexes. at the same time, this thesis has also researched arenaceous source on every part of mu us. firstly mu us desert ' s forming process is deeply influenced by the east asian monsoon, the grain size gradually becomes smaller, while the magnetic susceptibility becomes larger from northwest to southeast this phenomenon not only appears on the surface of mu us, but also obviously reflects on the same layer of different places
根據大量野外詳細考察和室內樣品分析與測試，本文對毛烏素沙地全新世地層沉積特徵做了細致的探討，尤其對區域地層的粒度組成特徵做了進一步的研究，突破了以往的定性描述，得出了一系列量化指標；結合野外的考察工作，對其不同地區的沙質來源做了詳細分析，主要得出以下結論： 1 、毛烏素沙地形成過程深受東亞季風影響，粒度自西北向東南逐漸變細、磁化率值逐漸變大。Contents are likewise clear indicators of who ' s who by what ' s what : fish scales and crayfish parts suggest otter, says halfpenny in his field guide
同樣地，成份也是明顯指標，因為某些動物吃的就是某些食物，哈夫彭尼在他的野外指南寫道：如果內含魚鱗和螯蝦殼，表示是水獺的。After current data analysis and field investigation, the authors consider that the xiangfan - guangji fault is a composite fault belt making up of various subgrade faults of different ages, including the early - stage ( indosinian - yanshanian ) southward thrust and late - stage ( himalayan ) northward thrust
摘要本文在系統總結現有資料的基礎上，運用板塊構造理論和現代造山帶研究方法，通過野外工作，指出襄樊~廣濟斷裂（帶）是由多條不同時期斷裂組成的復合斷裂帶，它包括早期（印支~燕山期）由北向南的逆沖構造和晚期（喜馬拉雅期）由南向北的逆沖推構造。Guide to the acquisition and management of meteorological precipitation data - field practices and data management - data management
