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格局進行定,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散程度.本研究採用無樣方法,定不同生境的格氏栲種群空格局,分析格氏栲種群格局的強度和紋理.強度以聚塊和隙的密度差來定義,紋理則是體現聚塊內個體散程度與諸聚塊的分程度.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.這一定結果與作者採用聚集度指定相同樣地格氏栲種群空格局的結果基本相符.因此,格氏栲空格局類型及分佈與格氏栲生物學特性及生境的關系密切

    低分辨isan成像及干涉技術應用研究一因此直接無法分辨編隊目的架數,我們借鑒isar的技術,通過較長時的相干積累,在多普勒頻域上對目進行分辨。而對于編隊目,可分為近似剛性的多目和非剛性的多目,所以對于可以近似為剛體的編隊目相對位置固定,運動方式一致,可以近似看作一個大目,採用最小墑準則對平動相位的進行補償,但是大多數並不滿足剛體近似的編隊目,由於目在相干積累時的多普勒頻率近似呈線性變化,通過對較短數據利用relax的時頻分析方法,提高了頻率域上目分辨的性能。由於橫向解析度取塊于橫向積累時,所以利用radnwigner變換得到瞬時的一維橫向像大大提高了對編隊目的分辨,對模擬和實數據的大量分析結果表明此方法的有效性和可行。
