Academic journals are the exchange of research results, dissemination and heritage information carrier. Public Health and Preventive Medicine discipline is an important part of medicine. The deepening of China's scientific and technological journals publishing system reform as one of the medical and health journals Periodicals, Preventive Medicine journals need to fully understand their own development characteristics, strategy thinking to solve its problems, in order to enhance their own capacity, more good preventive medicine career development services. 【Objective】 In order to improve the overall level of Chinese Journal of Preventive Medicine, effective in the country, internal and external dissemination of public health prevention of medical disciplines latest scientific research, to enhance the core competitiveness Journal of Preventive Medicine, enhance journals branding, promotion of preventive medicine and public health development, the better to promote the cause of public health, this study is based on analysis of the strengths and weaknesses of the Periodicals bibliometric indicators, to explore the impact of preventive medical academic journal of the quality of the main factors. 【Methods】 screening preventive medicine and health science class two Chinese HowNet and Wanfang data database journals navigation system in all 73 academic journals as the research object. Bibliometrics analysis above Periodicals overall basic characteristics, the characteristics of the development of indicators and sources of indicators, as well as changes in the journal of Environmental and Occupational Medicine core characteristics. Main sources of data: the printed edition of the journals, the Chinese HowNet Chinese academic journals Network publishing pool, Chinese Citation Database, Chinese Academic Journal Evaluation Statistical analysis platform, \Literature Publishing House) and the Chinese Academic Journal Comprehensive Citation Report 2008 Edition \years), the period of the fastest growing number of periodicals, 1970s and 1980s, its growth rate exceeding 200%; the journals sponsored mainly concentrated in North China, accounting for 43.8%, which Beijing accounted for 27.4% of the total; As of 2010, publishing cycle to bimonthly, accounting for 49.3%, Xunkan and semimonthly 4 (5.47%); 23% organizers for the China Preventive Medicine Association; printing quality is generally good, the cover design beautiful and prominent features; networks low level of information technology, there is an independent website accounted for 24.3%, 30.1% rely on the public database or organizer website, there are 38.4% of the journals did not provide a public web site, only the three developers access journals. Website link popularity popularity and similar international names published large gap (average of 104.8 and 357 223). The average delay in publication for 178 days. Email feedback service is generally good, 69% of the journal for readers' advisory reply within 24 hours. The relatively centered journal development features bibliometric study (1) all 73 kinds of preventive medicine journals, bibliometric indices (impact factor and citation frequency) average Periodicals, significantly lower than the core The average level of the journals. Median total cited frequency of 6239, the cited amount of 1.56 h index 22.5; sources of indicators: total Posting 4061, downloads 68763, chapter citations 1.07; indicators in 2007 when the median : the total cited frequency of 742, Impact Factor 0.392; total of published articles 259, the download rate of 14 the Fund paper than 0.130. (2) 34 core journals of impact factor and citation frequency were significantly higher than the the entire journal group average, close to the overall average of the China Science and Technology journals. Total cited frequency of an average of 690, the average impact factor 0.436, significant differences between the 34 core journals impact factor, maximum 1.436, minimum 0.080. (3) from 2001-2009, reflects the periodical influence four key indicators (impact factor, average downloads, immediacy index, cited half-life) showed an upward trend. (4) The correlation analysis shows that founded the number of years with the Posting amount, downloads, the total is cited frequency and h index showed a positive correlation; correlation analysis also show total cited frequency and impact factor, immediacy index, reference published number of disciplines impact and diffusion The indicators have a strong correlation. (5) Multiple linear regression analysis found that the main factors of the power index is a five-year impact factor, cited half-life, total citation frequency and network download rate, no significant relationship with impact factor. Logistic regression analysis found that if you only consider the basic characteristics of the journal as the independent variable, and found that: only affect the quality of journals founded a number of years and English summary of the two factors meaningful. 3, the data provided by the characteristics of Chinese scientific papers Source Journals directory of Environmental and Occupational Medicine core journals of Environmental and Occupational Medicine core journals seven kinds, namely, Industrial Hygiene and Occupational Diseases \\Its founding time between the 1970s and 1980s, the magazine shorter history compared to some of the best preventive medical journals. Which accounted for three bimonthly, monthly 3 a half months. The various publications cover design and Journal Period optimization; bibliometric indicators in the Journal of Preventive Medicine center and other level; 1986 Dao 2006 Nian, the indicators of development is not balanced, but overall was a sustained and stable rising trend; degree of network information different, there are two journals online remote Contributor, and the individual journals not yet established their own websites or web content updates is not enough time. [Conclusion] of Preventive Medicine journals from the 1950s successively founded Periodicals gradual increase in the number of publishing quality, printing quality, service quality continuously improve; bibliometric indicators (the indicators and sources cited indicators) average level close to the average of the overall national journals; nearly 10 years, the average level of the indicators increased steadily, but the uneven development of various publications, indicators significantly different; degree of access to the network of information technology and development is relatively lower than China's scientific and technological journals overall level, there is still a lot of room for development.
