  1. 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種群空間格局,分析格氏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米櫧虎楠木荷;格局紋理從粗到細的順序是:木荷=木姜子茜草樹格氏=冬青米櫧蚊母樹虎楠.這一測定結果與作者採用聚集度指標測定相同樣地格氏種群空間格局的結果基本相符.因此,格氏空間格局類型及分佈與格氏生物學特性及生境的關系密切

    改性橡木宛膠鞣製牛沙發革工藝的探索
  3. The result showed that the biomass of different organs of chinese - fir treated with aqueous extracts of schima superba, castanopsis fargesii and pinus massoniana after six years were increased in some degree, the higher the concentration was, the higher the positive effect was, and low concentration had positive effect on the bark, branch and litter biomass distribution, high concentration had positive effect on the leaf, root and stem biomass distribution ; that the biomass of chinese - fir treated with cunninghamia lanceolata after six years were decreased, the higher the concentration was, the higher the inhibited effect was, and low concentration had positive effect on the leaf, bark, root, branch and stem biomass distribution, high concentration had positive effect on the litter biomass distribution

    結果表明絲栗、馬尾松、木荷水浸液處理杉木6年後,各器官的生物量有不同程度的提高,隨著濃度加大其促進作用增強,在低濃度時有利於、枝和枯枝落葉生物量分配率,高濃度時有利於葉、根、乾的生物量分配率;杉木水浸液處理杉木6年後,各器官生物量有不同程度的降低,隨著濃度加大其抑制作用增強,在低濃度時有利於葉、、根、枝和乾等各器官生物量分配率,高濃度時有利於枯枝落葉生物量分配率。
