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儀數據提取地物信息的基礎；發現了基於光譜整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整體平移的「同物異譜」現象，對于譜形相似而整體反射率的值相差較大的兩類地物，通過引入均值和方差圖像參與分類得到解決；研究還表明在植被「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。It was too hot, and the glare of the candles above the table grew ever yellower and duller. now and again, when a women bent forward, the back of her neck glowed golden under a rain of curls, and the glitter of a diamond clasp lit up a lofty chignon
房間里太熱，桌子上空的蠟燭的光亮越發變黃，並漸漸昏暗下來。不時，一個頸背上披蓋著金色鬈發的脖子向前一彎，綴滿鉆石的發扣發出熠熠光芒，照亮著高高的發髻。In this graph, the galactic plane is horizontal and we ignore the distances. note that the gas and dust in our galaxy not only block the stars in our galaxy, but also the galaxies far away. taking this into consideration, the distribution of the galaxies is fairly uniform
圖中中間的水平線標示出銀河系平面，銀河系的氣體塵埃除了掩蓋了背景星光，亦同時遮蔽了遙遠的星系，撇除了這個因素，我們會發覺星系在天空的分佈是頗為平均的。En 1816 resilient floor coverings. specification for homogeneous and heterogeneous smooth rubber floor coverings with foam backing
