Abstract: For analyzing the Yangtze River features of Journal of Yangtze River Scientific Research Institute, taking published theses from the fourth issue, 2007 to the fifth issue, 2010 as the samples, the authors analyzed the data extracted from Online Publishing Pool of China Academic Literature of China National Knowledge Internet (CNKI), which includes four aspects such as subject category, download frequency, author group, and assistance fund of papers. The statistical analysis results show that： (1) the papers are distributed over 41 kinds of first level disciplines, of which the main disciplines are water conservancy and hydropower engineering, accounting for 54 percent of the number of total theses, followed by architerctural engineering and geophysics, accounting for 12 percent respectively； (2) The author group mainly is the researchers working at the forefront of water conservancy industry in the Yangtze River valley ； (3) Among the theses gaining the national natural fund assistance, those reporting Yangtze River Health account for 43%. Therefore, Yangtze River Features of Journal of Yangtze River Scientific Research Institute are reflected in the scientific achievements written by the researchers working at the forefront of water conservancy industry. In recent years, there has appeared a tendency in papers, i.e., content of this Journal from engineering water conservancy expanding to resource water conservancy.
