Abstract: This study focused on traditional dairy products and the modern dairy industry in Heilongjiang Province,employing methods such as literature review and process analysis to systematically examine the historical origins,geographical and ecological context,traditional production techniques,cultural value connotations,industrial evolution,and existing challenges of Heilongjiang's traditional dairy products. The research revealed that Heilongjiang's dairy industry has developed a distinctive path—rooted in the cold-region black soil and high-quality Leymus chinensis resources of the Songnen Plain—integrating three key elements:remnants of ancient northern nomadic,fishing,and hunting cultures,the introduction of Russian techniques,and the pioneering industrialization of New China. This model significantly differed from other regional dairy development patterns. By proposing development strategies centered on cultural heritage preservation and regional brand building,the study provided both theoretical insights and practical guidance for the quality transformation of Heilongjiang's dairy industry.

Key words: Heilongjiang dairy industry, traditional dairy products, dairy culture, localization of Russian dairy techniques, dairy history, regional branding
