[en] The paper presents results of correlation between cosmic ray intensity and solar activity for two last solar cycle 1957-1976. Positive correlation between solar activity and cosmic ray intensity was found for the definite heliolatitudes for 1974-1976. It is suggested that cosmic ray modulation is produced by shock waves and streams of solar wind. Coronal holes may be sources of solar wind
