With the emergence and further development of the digital library,the approaches of information acquisition correspondingly change a lot.This paper makes a statistical analysis on the joal downloading and citation behaviors under the digital environment conceived by the National Science Library (NSL),Chinese Academy of Sciences (CAS).It can be seen that the development of digital resources has influenced scientific research behaviors.For example,the large quantity of full-text downloading will maintain;the trend of joal downloading behaviors is basically same as the joal citation behavior;joals with large quantity of full-text downloading also boast the high cited times,and vice versa.Furthermore,authors make a linear regression analysis,with the joal downloading amount as the independent variable and joal cited times as dependent variable.Then they also prove the positive correlation between the jonmal downloading and citation behaviors by means of Pearson’s correlation coefficient formula.
