摘　　要：运用多变量形态度量学和框架结构形态学的方法,测量了采自滇池流域6个不同地点的149尾滇池金线鲃(Sinocyclocheilus grahami)的标本。应用多变量形态度量学分析,选择了20个框架结构性状和19个常规性状,进行主成成分分析。主成成分分析结果的散布图显示,6个不同地点的标本聚在一起没有分开,表明滇池金线鲃的各居群之间在可数性状和可量性状上均未表现出明显的差异,说明滇池金线鲃在形态上还未发生明显的种下分化。One hundred and fourty-nine specimens of Sinocyclocheilus grahami from six different localities of Lake Dianchi area were examined. Twenty frame and nineteen general characteristics, thirty-nine characteristics in sum were measured for multivariate morphometrics analysis. Based on the results of principal components analysis, specimens clustered together by scatter plots of scores could not be divided. It indicated that there is no morphological diversification under species level.
