Citation frequencies of scientific articles are increasingly used for academic evaluation in various disciplines, including ecology. However, the factors affecting citation rates have not been extensively studied. Here, we examine the association between the citation frequency of ecological articles and various characteristics of journals, articles and authors. Our analysis shows that the annual citation rates of ecological papers are affected by the direction of the study outcome with respect to the hypothesis tested (supportive versus unsupportive evidence), by article length, by the number of authors, and by their country and university of affiliation. These results cast doubt on the validity of using citation counts as an objective and unbiased tool for academic evaluation in ecology.
科学文章的被引频次越来越多地用于包括生态学在内的各学科的学术评价。然而，影响被引率的因素尚未得到广泛研究。在此，我们考察了生态学文章的被引频次与期刊、文章及作者的各种特征之间的关联。我们的分析表明，生态学论文的年被引率受到研究结果相对于所检验假设的方向（支持性证据与非支持性证据）、文章长度、作者数量及其所属国家和大学的影响。这些结果对将被引次数用作生态学学术评价的客观且无偏倚工具的有效性提出了质疑。
