Abstract: ［Purposes］There is few research on modern Chinese hydraulic scientific and technical periodicals and there is still a blank of the relevance of contemporary and modern hydraulic scientific and technical periodicals. Therefore, the inheritance and development of modern Chinese hydraulic scientific and technical periodicals are introduced to solve the problems mentioned above.［Methods］ Modern and contemporary scientific and technical periodicals, historical records of hydraulics and papers of CNKI and the retrieval database were studied, counted, compared and comprehensively analyzed. The dissemination and influence of modern scientific and technical periodicals were summarized. The concept of source journals was presented, and the problem of no correlation between contemporary and modern hydraulic scientific and technical periodicals was discussed. ［Findings］ The former has inheritance and important development in terms of the publication history, the covering branch of hydraulic science, the breadth and depth of papers, the academic and social influence and the overall level. Contemporary hydraulic scientific and technical periodicals have more profound historical accumulation, as well as academic and social impact. It was confirmed that modern hydraulic scientific and technical periodicals were indeed the root of contemporary hydraulic scientific and technical periodicals. ［Conclusions］ The inheritance and development of the root shows contemporary hydraulic scientific and technical periodicals respect history and science. It is helpful to improve their overall level.
