  1. Compared with the classical bp algorithm, robust adaptive bp algorithm possesses some advantages as following : ( 1 ) increasing the accuracy of the network training by means of using both the relative and absolute residual to adjust the weight values ; ( 2 ) improve the robustness and the network convergence rate through combining with the robust statistic technique by way of judging the values of the samples " relative residual to establish the energy function so that can suppress the effect on network training because of the samples with high noise disturbances ; ( 3 ) prevent entrapping into the local minima area and obtain the global optimal result owing to setting the learning rate to be the function of the errors and the error gradients when network is trained. the learning rate of the weights update change with the error values of the network adaptively so that can easily get rid of the disadvantage of the classical bp algorithm that is liable to entrap into the local minima areas

    與基本bp演算法相比，本文提出的魯棒自適應bp演算法具有以下優點： （ 1 ）與魯棒統計技術相結合，通過訓練樣本相對偏差的大小，確定不同訓練樣本對能量函數的貢獻，來抑制含高噪聲干擾樣本對網路訓練的不良影響，從而增強訓練的魯棒性，提高網路訓練的收斂速度； （ 2 ）採用相對偏差和絕對偏差兩種偏差形式對權值進行調整，提高了網路的訓練精度； （ 3 ）在採用梯度下降演算法對權值進行調整的基礎上，通過將學習速率設為訓練誤差及誤差梯度的特殊函數，使學習速率依賴于網路訓練時誤差瞬時的變化而自適應的改變，從而可以克服基本bp演算法容易陷入局部極小區域的弊端，使訓練過程能夠很快的「跳出」局部極小區域而達到全局最優。
  2. Longgang nature reserve plays an important role in preserving two langur species of both white - headed langur and francois langur. interview and field survey methods were used to survey the distribution and population size of these two langurs in this natural reserve from december 2001 to january 2002. the result indicated that the reserve has 8 groups of white - headed langur with 68 individuals in longrui and 10 groups of francois langur with 75 individuals in longgang. the distribution area and population size of both of the two langurs in this reserve have greatly declined in the past decades. they are seriously threatened and have high risk of disappearance from this reserve if no effective measures are to be taken at once

    為了確定弄崗自然保護區內白頭葉猴的種群數量，彌補黑葉猴種群數量的空白，掌握此保護區葉猴的生存現狀，採用訪問法和實地數量統計法相結合的方法對弄崗自然保護區的弄崗、隴瑞和弄呼3個部分進行深入的調查研究.調查結果表明，在隴瑞片范圍內，共有8群白頭葉猴，種群大小在68隻左右，和20世紀80年代末的244隻相比，數量下降相當驚人;在弄崗片內，共記錄到黑葉猴群10群，最大的種群為11隻個體，最小的種群是4隻個體，共計約有75隻黑葉猴（絕對數量統計） ;弄呼的黑葉猴種群已經于上個世紀的晚期消失.造成目前狀況的因素主要是過度狩獵和其他形式的過度干擾.弄崗自然保護區的葉猴種群數量已經接近可持續繁殖種群的最低水平，如不採取有效的保護措施，這個種群將很可能在短期內消失
  3. The results show that : in the 2 - 4m of road buffer zones and 0 - 10m of infrastrctuer buffer zones, the density of dominant species and biomass will decrease for herbs, and abundance and proportion will get bigger than other exents ( inner species increasing owing to the outer species invading ) ; in the shrub disturbence extent, there exists an inverse relationship between the influence degrees and buffer zones ; in the 40m of infrastructure buffer zones, there has the biggest influence on the trees, however, the effect of road buffer zones is unobvious, only a small change on the morphology

    結果表明，草本類，游道影響源干擾區在2 4m ，設施類在0 10m ，原有優勢種密度減小，物種豐度較其它干擾范圍內有所增加（外部種入侵導致本地植物的種類數目增多） ，均勻度也增大，生物量減少；灌木類，在干擾范圍內，影響程度與影響源的距離成負相關關系；喬木類，接近設施類40m處影響最大，游道類影響源則影響效果不明顯，只有形態上略有變化。
  4. Based on the analysis of present commonly used scene matching area selection algorithms, this thesis presents a new a approach in the selection of scene matching area, gis supported scene matching area selection based on image content. the new method shows great efficiency in solving the problems faced in present algorithms, which are high reliance on image quality, low resistance to noise, low veracity and mass process time

    依據本文提出的基於最小誤判概率的景象匹配區選擇方法評價標準對目前常用的景象匹配區選擇方法進行評價后，針對現有方法受圖像質量影響較大、抗干擾能力低、準確性低以及計算量大等多方面的問題提出融合圖像內容的景象匹配區選擇方法。
