摘　　要：测量了等边浅蛤壳长、壳宽、壳高等壳体性状和湿全重、软体部湿重、软体部干重等经济性状．分析表明,等边浅蛤各性状间的相关系数均达到显著水平．壳高与壳长,壳高与壳宽,湿全重与软体部湿重,湿全重与软体部干重之间均呈线性正相关,可用线性回归方程模式表示:Y=a+bX;壳长与湿全重,壳长与软体部湿重,壳高与湿全重,壳高与软体部湿重之间均呈幂函数关系,可用幂函数回归方程表示:Y=aXb．建立了经济性状与壳体形态性状的多元回归方程．In this paper, the shell length, shell width and shell height of Gomphina aequilatera were measured; me economic character of live body weight and tissue weight were also weighed. The results revealed significant phenotype correlation between the parameters （P 〈 0.01）. Shell length was liner to shell height, and so was shell width to shell height; live body weight to tissue weight; live bodyweight to dry tissue weight, which can be figured as the liner regression equation： Y=a ＋ b · X. Shell length was power function to live body weight and tissue weight; and so was shell height to live body weight and tissue weight, which can be figured as the multiple regression equation ： Y = a·X^b. The multiple regression equation was set up between the economic characters and the shell＇s shape.
