Abstract：
Through the analysis of the various factors which affect the intensity of γ-families observed by mountain emulsion chamber and the comparison of the experimental data with the results from Monte-Carlo simulation,the inference that the proton fraction in primary chemical composition at UHE region,say 10¹⁵ eV,is about 30% is proved to be acceptable.
