摘      要：With statistical analysis of Weibo altmetrics indicator, the paper explored features of a typical altmetrics indicator in Chinese environment. Results show that the coverage of Weibo is below 1%. However, the coverage is underestimated due to limitation of tracking time and objects. Weibo mentions and discusses articles mainly from disciplines like General , Biochemistry, genetics and molecular biology , Health science , Medicine and Life science etc. In addition to traditional distinguished interdisciplinary journals like Nature, preprint platform and open access journal like ar Xiv, PLo S ONE and SSRN also drew much attention from Weibo. Meanwhile, Biology Science and Medical science have the most highlighted journals. Weibo mainly tracks latest articles, reflected in that articles tracked within 180 days occupy 68.66%, it also tracks classic articles. Weibo authors prefer to disseminate, recommend and criticize articles that are adherent to daily life, funny, useful or related to health, which conveys social value and scholarly value beyond citations. Weibo altmetrics indicator is highly scattered and concentrated. 5.1% of the articles have harvested 50% of the weibos. Besides, articles tracked by Weibo gain global attention much higher than the average level.
