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。 -
At the same time 7794m3 affusion test were processed, and roadbed settlement observation conducted for two more year, physical mechanism and chemical index experiment were analyzed in the laboratory, section experiment of earth sample was proceed, changement of compacted soil body micromechanism along with depth were analysed by polariscope and scan electricscope. drain ditch, barrel - drain and little bridge were treated by composite geotextile
在室內進行了物理力學、化學指標實驗分析，並對土樣結構進行了切片試驗，用偏光顯微鏡和掃描電鏡分析了土壤碾壓后沿深度分佈的土體微觀結構變化情況，對邊坡、邊溝、排水溝、小橋涵及護坡封水採用復合土工布進行處理。 -
According to the author ' s experience this paper presents the main problems which should be regarded in laboratory soil tests, including sample preparation, the oven temperature selection in water content test, level consolidation test, direct shearing test and so on
摘要根據作者長期從事土工試驗的經驗，闡述了在室內土工試驗時，樣品制備、含水率試驗烘箱溫度選擇、水平固結試驗和直接剪切試驗中應該注意的問題。 -
The test results in the no - tillage fields with corn rootstalks shown that the sample machine has a good ability to cut and dig corn rootstalks only in the seed beds so that the new no tillage planter can create a good condition of seed bed and have lower power consume. 2 system experiment is conducted to investigate the mechanical properties of rootstalks and soil rootstalk composite. the experiment results include : ? he maximum cutting force decreased exponentially with increasing cutting speed and the moisture contents of rootstalks
通過對新型免耕播種機的田間生產試驗，證明了切挖處理播種帶玉米根茬原理可行，所開發的機具結構新穎，具有創新性；該機不但能創造無根茬的良好種床條件，有利於種子生長發芽，而且不需大量粉碎根茬，因而擾土量少、整機消耗動力小、破茬入土能力強，有利於充分發揮保護性耕作的優勢。 -
