  1. 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方式,包括林地、果園、耕地、棄耕地和灌草,採野外巖溶生態調查和室內驗測量分析相結合的方法,以不同土地利方式巖溶土壤肥力為重點,對不同土地利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、有機質層厚、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及結構的調控管理提供依據。
  2. When catchment area, average channel gradient and catchment shape factor of designed culvert or bridge are known, a user can be convenient to get local parameters c, e and b from standard contour charts and easy to calculate flood flow just by a calculator. design period of flood flow is enormously shortened as well as a high precision. estimated flood flow through culvert or small bridge by new calculation model is generally less than by traditional methods, so that much cost is cut down a s reducing the span of culvert or small bridge

    以75000km ~ 2的川中丘陵地區為點研究區,繪制了該地區新模型的參數等值圖,率定了不同設計頻率的改正系數,使設計者只需在地形圖上獲取集水面積,河道平均降和流域形狀系數,在參數等值圖上查得橋涵所在地的相應參數,使計算器即可迅速計算出設計流量,大大縮短了設計周期,且精較高,設計的洪水流量一般低於傳統方法,從而可減小橋涵跨徑,節省投資。
  3. With reference to calculation methods of solar radiation within domestic and abroad literature and with the help of our country ' s dem ( with its resolution is 1 km x 1 km ), we build a new model for potential solar radiation calculation combining with pci geomatica ' s platform. in the calculation, hypothesis is that insofar one clear day in more than one year as the biggest value of solar radiation of one day in many years is defined as potential value of daily global solar radiation, we also consider the infection of the slope, aspect and its geometry relations affect on solar radiation. we calculate potential solar radiation which maybe useful for research the distribution of solar energy and build large - scale grid database of our country ' s solar radiation
