Abstract: This paper takes the first-level environmental science and engineering of 20 universities in Beijing, Tianjin and Hebei as an example, and selects the data of the core of Web of Science for nearly ten years (2009-2018) to explore multi-dimensional subject evaluation methods. The macro dimension selects the total number of papers, the total number of citations, the number of times of citations, the index of h, the average annual growth rate, and analyzes the overall development of the subject from the two aspects of the number and quality of the papers. The number of publications has increased year by year. The h-index of Tsinghua University, Peking University and Beijing Normal University ranks in the top three, but the number of citations of Beijing Normal University academic papers needs to be improved. Further, through academic traces and academic matrices, the specific gaps between colleges and universities are analyzed from the microscopic aspects. Among the 20 universities, except for Tianjin University of Technology, the proportion of zero-cited papers is low. The papers published by North China Electric Power University can be quickly recognized and quoted by person of the same occupation. Tsinghua University has a large number of papers in the h-tail area.

Key words: subject evaluation, academic track, academic matrix, h index
