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These bacteria are transmitted through the cytoplasm of eggs and have evolved various mechanisms for manipulating reproduction of their hosts, including cytoplasimic incompatibility ( ci ), parthenogenesis, feminization, male killing, fecundity or fertility modifying etc. wolbachia are common and widespread bacteria infecting 17 % insect population, 17 crustacean species, mites and many nematodes
