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。Previous researchers have always determined the sp atial distribution patterns ( sdp ) of castanopsis kawakamii with a sample - dis tance method. however, the distribution patterns may be affected by the quadrat si ze and, in the course of analysis, the density differences among the cluster plots are not considered ; therefore, differences of cluster plot size and the dispersi on degree among individuals of cluster plots can not be known. authers of this pa per have determined the spatial distribution patterns of castanopsis kawakamii population in different habitats by means of non - quadrat distance method and a nalysed the pattern intensity and grain of the sdp. the pattern intensity is defi ned with the relative density differences and the pattern grain can embody the d ispersion degree of the individuals in the plots, and the dispersion degree among the plots. the determined results are as follows. the intensities of the species range in order from strong to week : litsea mollifolia p. kawakamii i. purpure a r. cochinchinensis c. kawakamii c. carlessii d. oldphamii s. superba. the gra ins of the species queue in order from coarse to close : s. superba = litsea mollif olia r. cohinchinensis c. kawakamii = i. purpurea c. carlessii p. racemosam d. oldp hamii. these determined results tally basiclly with the results authers of this paper have got in determining the same plots by means of aggregate index access ing method. in view of this, it is held that the sdp of c. kawakamii is closely related to the habitats and biological features
前人都是採用樣方方法對格氏栲種群數量的空間格局進行測定,而格局分佈有可能受樣方大小的影響,且分析過程中沒有涉及聚塊間密度差的問題,因而無法掌握種群的聚塊大小差別及聚塊內個體間的離散程度.本研究採用無樣方距離法,測定不同生境的格氏栲種群空間格局,分析格氏栲種群格局的強度和紋理.強度以聚塊和間隙的密度差來定義,紋理則是體現聚塊內個體間的離散程度與諸聚塊間的分離程度.測定結果表明,格氏栲種群格局強度從高到低排列次序為:木姜子蚊母樹冬青茜草樹格氏栲米櫧虎皮楠木荷;格局紋理從粗到細的順序是:木荷=木姜子茜草樹格氏栲=冬青米櫧蚊母樹虎皮楠.這一測定結果與作者採用聚集度指標測定相同樣地格氏栲種群空間格局的結果基本相符.因此,格氏栲空間格局類型及分佈與格氏栲生物學特性及生境的關系密切As dormitory is often occupied with students, correspondingly flammables such as books, quilts, clothes ; mosquito curtains account much, once fire accident happens, it sprawls easily and rapidly ; moreover inflammables, explosives and chemicals stuffed in laboratory, if not taken carefully, tend to cause fire or explosion
