The results indicate that : 1. the main physical and chemical characteristics vary regularly : with rising of the altitude, there is a transition from silt > sand > clay to sand > silt > clay in the mechanical composition ; the argic horizon emerges below the altitude of 1600 meters ; the content of organic matter is enrichment, the content of organic carbon of epipedon is higher than 20 g / kg, while the content of organic carbon increases with increasing of altitude, and in the altitude of 3500 - 3700meters, the soils under the meadow have the maximum content organic carbon ; the soils appear acid - slightly acid reaction, the ph decreases appreciably and acid strengthen with increasing of altitude ; the soils higher than the altitude of 2500 meters are base unsaturated, indicating the soil leaching is strong, the ph and bs are distinct plus correlated ; the contents of sio2, al2o3, and fe2o3 of the soil body and clay are all relatively stabilization ; in the soil body, the content of sio2 is much high and cao is very little, the total contents of sio2, a12o3 and fe2o3 occupy 92 % of the mineral parts, the sequence of mineral elements is : sio2 > al2o3 > fe2o3 > k2o > mgo > cao > tio2 > mno

研究結果表明： 1太白山南坡土壤的主要理化性質隨海拔高度的上升呈有規律的變化：隨海拔高度上升，機械組成由粉粒砂粒粘粒逐漸過渡到砂粒粉粒粘粒，海拔1600m以下出現粘化層；土壤有機質豐富，表層有機碳含量一般在20g kg以上，有機碳含量隨海拔高度升高而相應增加，海拔3500 3700m的灌叢草甸植被下有機碳含量最高；土壤呈酸性或微酸性，並隨海拔上升， ph值略微降低，酸性增強，海拔2700m以上的土壤多呈鹽基不飽和狀態，表明土壤淋溶作用較強， ph值和鹽基飽和度呈極顯著正相關；土體與粘粒中的sio _ 2 、 al _ 2o _ 3 、 fe _ 2o _ 3含量相對比較穩定，土體中sio _ 2含量較高， cao含量較少， sio _ 2 、 al _ 2o _ 3和fe _ 2o _ 3含量之和約占土壤礦質部分的92 ，礦質元素含量的順序依次為： sio _ 2 al _ 2o _ 3 fe _ 2o _ 3 k _ 2o mgo cao tio _ 2 mno 。

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。
