Abstract：
The strangeness production in high energy pp collisions is studied by considering the constraint from the isospin conservation and the suppression of strange quark production. The multiplicity dependence of the ratios K⁺/π⁺and K^－/π^－ is given, and an approximately parameter independent ratio of (K⁺/π⁺)/(K^－/π^－) is proposed to reflect the constraint of isospin conservation.
