群落相似性群落相似性similarity of community 可以更明确地描述种组成相似特征。常用的有杰卡特(P.Jaecard,1901)、索雷申(T.Sorensen,1948)、库列津斯基(5.T.Kulezynski,1927)和芒福德(M.D.Mountford,1962)等的相似性系数。 设丈为生境A和生境B共有的种数,a为生境A含有的全部种数,b为生境B含有的全部种数,则:①杰卡特群落相似性系数: G=j八a+b一户;②索雷申群落相似性系数: CS=Zj八a+b);③库列津斯基群落相似性系数:。一冬cs一j八。+b); ‘④芒福德群落相似性系数: C材=Zj/(Zab一(a+b)j〕 上述杰卡特群落相似性系数(G)和索雷申群落相似性系数(Cs)的最大值为1,库列津斯基群落相似性系数(C砂的最大值为0.5;芒福德群落相似性系数(C耐)的最大值为co。当两个群落所含有的种完全相同,其系数为最大值;当两个群落所含有的种完全不同,其系数均为O。自O至最大值之间表示两个群落的相似程度。 优势种相似上述的群落相似性系数得出的指标虽不尽相同,但原则一致,其特征值仅限于比较群落间所含有的种的相似性。但两群落的外貌是否相似,常常以优势种的相似程度为特征。因此,布雷和柯蒂斯(J.R.Bray and C.T.Curtis,1957)根据上述群落相似性系数,结合优势种的相似程度进行描述,即在生境A和B中,以全部种的个体总数aN和bN代替索雷申群落相似性系数计算式中的口和b,取两生境中共有种的种群数量的低值(例如种1在生境A中种群数为47,在生境B中种群数为50,则取47为计算值)的总和方明弋替;’,其相似性系数CB为: CB=2.1’N尹(口N+云N)。 计算结果同样以O至l之间的数值表示两个群落之间的相似程度。(庞雄飞)群落相似性(similarity of eommunity)群落特性之一,是不同群落结构特征的相似程度。常用群落相似性系数(eoeffieient of similarity)表示。可用以比较不同空间昆虫群落结构的异同。 共有种相似假如A、B、C三个群落的种类数从本一致,群落A与B具有多数共有种,群落B与C仅有少数共有种,可以认为群落A与B的相似性较大,群落B与C的相似性较小。 种组成相似在物种构成相近似的群落中,不宜单纯依据共有种的数量比较其相似程度,用群落中种类总数及共有种数的综合性指标—群落相似性系数,
