  1. And understanding and studying the spectral features and variation rules of geo - targets in the experimental area, raising that it is the basis of geo - targets information collection with imaging spectrometer data to understand spectral features and variation rules of geo - targets, realizing that in a great extent spectral - integrated - form - based classification method can remove the phenomenon of " different spectrum with same objects " resulted from reflection ratio curve translation because of the angle change among sensor, targets and observation direction, and the average and variance images can be introduced to solve the problem of two kinds of geo - target with similar spectral forms and much different values of whole reflection ratio. it is suggested that " red edge " range bands of vegetation, which has close relationship with vegetation cover and biomass, is the main characteristic bands and important basis for careful vegetation classification and quantitative retrieval, and pixel - based derivative spectral analysis is very useful for removing the effects of soil background values and quantitatively retrieving vegetation biomass and cover. the remote sense quantitative retrieval model is developed for main appraisable factors of desertification monitoring assessment with imaging spectrometer data and then the applicability of model is analyzed

    研究結果如下:首先針對荒漠化地區的地物特徵,對高光譜數據不同波段的數據質量、波段組合進行了評價,提出了適用於荒漠化監測的基本波段選擇集;初步了解和掌握了研究地區的地物光譜特性及變異規律,進一步明確了掌握地物光譜特徵和變異規律是用成像光譜數據提取地物信息的基礎;發現了基於光譜體形狀的分類方法在很大程度上能夠消除由於傳感器、地物目標觀測方向之間的角度變化引起的反射率曲線體平移的「同物異譜」現象,對于譜形相似而體反射率的值相差較大的類地物,通過引入均值和方差圖像參與分類得到解決;研究還明在植被「紅邊」范圍內的波段是進行荒漠化監測的主要特徵波段,這些波段與植被生物量和蓋度都有密切的關系,是開展精細植被分類研究和植被定量反演的重要基礎;像元的導數光譜分析可以消除土壤背景的影響,是進行植被生物量和蓋度定量反演的有力工具;建立了荒漠化監測主要評價因子的定量反演模型,並分析了模型的適用性。

  3. Based on the investingation and some study methods of the stability on the goaf, the paper has the goaf of the first and second tunnels of wu long channel on coal mine railway leased line in da ning of shanxi province as an example, according to the engineering geological invesitigation and maping in the earth ' s surface, also combining the visit on the relate people, firstly has a geological judge on the space extend of the mostly ledges which have been picked ; then adopts the instrument of engineering surveying and checking ( for short sws ) which is relatively advanced inside and outside to test by surface wave the rockmass and solid near the middle line of the tunnel ( total forty meter ), and has a relatively exact judgment on the place that the goaf impossible reveal ; lastly passing the validate by drilling, it make clear that the results which tested by sws is reasonable and believable, based on finding out clearly the space extend of the goaf, the author makes a relatively systemic study on the stability of wall rock around the goaf

    因此,查明采空區的具體位置,在此基礎上對場地進行工程適宜性評價,對個工程建設具有重要的指導意義。本論文在總結前人對地下采空區勘察及有關穩定性研究方法的基礎上,以山西大寧煤礦鐵路專用線五龍溝1 ~ # 、 2 ~ #隧道采空區為研究實例,在詳細的地工程地質調查和測繪的基礎上,結合通過對采空區有關人員的探訪,首先對主要開采礦層的空間展布進行地質判斷;然後採用國內外較為先進的工程勘探與檢測(簡稱「面波」 ) ,對1 ~ # 、 2 ~ #隧道中線側一定范圍內(共40米)進行了面波測試,對采空區的可能出露部位進行了較為準確的判斷;最後通過鉆探加以驗證,明面波的測試結果是較為合理可信的。
