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 second part used the river geography data get from gis into xiangshan reservoir dam - break simulation system
第二部分將gis所得到的河道地理數據用於象山水庫潰壩模擬計算。Application of seepage control wall technology of plasticity concrete in strengthen engineering of xiangshan reservoir
塑性混凝土防滲墻技術在象山水庫加固工程中的應用The first part mainly introduces the gis concept and contents of gis, the comparison between the related software and gis, the present condition and development trend of gis etc, then introduced how to use the gis technique in a specific way such as using the method of " the half - automatic to follow " to turn the map into arithmetic figure, using the method of " the automatic calculates " gets the length of the line and area of field etc, at last got the length and width of every cross section of the fabiela river which is located downstream of xiangshan mountain. this method is superior and time - saving comparing with collecting data on the spot, having important and actual application worth
第一部分主要介紹了gis的概念和研究內容， gis與相關軟體的比較以及gis的現狀、發展趨勢、當前gis研究的熱點等等，然後具體介紹了用gis的相關技術如：用「半自動跟蹤」方法對地圖進行數字化，用「自動量算」方法得到線對象的長度、面對象的面積等，最終完成了象山水庫下游法別拉河河道地形數據資料的提取工作，這種方法與人工實地採集工作相比，有較強的優越性和重要的實際應用價值。Using the mature product mapx, visual basic, visual fortran and sql server, a flood risk management system based on gis was developed and used in the lower reach of the yellow river
下，並以visualfortran作為水流模擬的開發工具， sqlserver作為數據庫管理和支持工具，以黃河下游山東段堤防潰決的風險管理為研究對象，開發了一套基於gis的洪災風險管理系統。分享友人
