蝕變指數
英文
index of alteration-
The efficiency and reliability of minerogenetic prediction can be improved by combining rs with gis. we processed rs images, extracted the geological information related to mineralizing, such as geology, structures, stratam, rocks, etc, synthetically analysed remote sensing, the geological data and geo - chemistry, under the guidance of the theory and mathematic model, set up gis mineralize model. on this condition, to develop this method and its theory, and to establish a system of perfect prediction, it is not only useful in studied degree area but also favorable for looking for new type and some form large - scale deposits in old studied area, and it has a great theoretical meaning
遙感與gis相結合用於成礦預測中可大大提高預測工作的效率和可靠性。通過對研究區的遙感圖像處理和地質、構造、地層、巖石、礦化蝕變等有關信息的特徵提取、遙感、地質數據和物化探數據的綜合與復合分析，在一定成礦理論和數學模型指導下，建立gis綜合找礦模型。在此基礎上，發展這一方法及理論並建立完善的預測體系，不僅對研究程度較低的新區礦床預測有用，而且對研究程度較高的老區尋找新類型和點狀大型、超大型礦床都具有重要理論意義和實際意義。Abstract : 145 samples of eight plants were collected from lanmuchang and yangjiawan and quantitative analyses were made of the ore - forming elements in the plant ashes. considering the three principles of the plant indicator for mineral exploration, namely certainty, sensitivity and feasibility, this paper evaluates comprehensively the indicating functions of the eight plants, on the basis of some quantitative indexes such as the relation coefficient between plant ash and ore - forming element, concentration coefficient, etc. it also discusses the relationships between the anomaly of plant ashes and the fault zone, alteration zone mineralization zone and orebody, showing the significance of these plants to the prospecting
文摘:在濫木廠和楊家灣鉈（汞）礦床（點）對芒箕、南燭、榔榆、大金發蘚、蜈蚣草、石松、黃花草、醉魚草等8種植物取樣145件，在提出確定找礦有效指示植物三原則（確定性，敏感性，可行性）的基礎上，依據植物灰分與底質成礦元素相關系數、植物灰分富集系數和襯度系數，較全面地分析和評價了8種植物的找礦功能；討論了其異常的分佈與斷裂帶、蝕變帶、礦化帶以及工業礦化（礦體）之間的關系，並指出了其找礦意義。Beginning with the problem of interlaced region between farming and herding, the boundary line of the interlaced region is calculated based on grid with 10km grid ; then the relation among land use of the region, soil erosion and erosion region is analyzed ; based on factor classification, no useful factors were neglected and stepwise regression method was used to analysis the drive of land use change ; fractal method was applied to analysis the degradation of land - use and relation among land use, soil erosion and wind - water erosion zone ; environmental variances are introduced to establish characteristic index of land use change and analysis the effect of land use change on soil erosion
從農牧交錯帶的實質問題入手，基於10公里網格，計算農牧交錯帶的界限；在此基礎上分析農牧交錯帶的土地利用、土壤侵蝕及與風水侵蝕帶的關系；在因子分層的基礎上，剔除不需要因素，採用逐步回歸的方法，進行土地利用變化驅動力分析；運用分形方法分析土地利用的退化，並分析土地利用與土壤侵蝕的關系，引入環境變量，建立土地利用變化特徵指數，分析土地利用變化對土壤侵蝕的影響。And it is indicated that the corrosion residual life of the pressure vessel and pipeline shouldn ' t be calculated with normal distribution model since the coefficients of variation of maximal corrosion depth and corrosion rate are often more than 0. 2
最後指出最大腐蝕深度和腐蝕速率等參數的變異系數往往大於0 . 2 ，因此不宜用正態分佈模型進行壓力容器與管道耐腐蝕剩餘壽命的計算與分析。The land use structure indexes and soil erosion intensity indexes in sichuan province are calculated and the results show that the changing trend of the land use structure indexes is in accord with that of the soil erosion intensity indexes, proving that the prediction of soil erosion intensity with the land use structure indexes is reasonable and practical
摘要研究計算四川省土地利用結構特徵指數和土壤侵蝕強度指數結果表明，該省土地利用結構特徵指數與土壤侵蝕強度指數的變化具有同步性，用土地利用結構特徵指數預測其土壤侵蝕強度變化是合理可行的。分享友人
