On the base of Pearson correlation coefficient indicate that the connection between IBI and CQHEI is higher than IBI and ISC of Juoshuei river basin. To the section of the upper and middle reaches, we suggest choosing simple and convenient SIAM to be the standard for environment in the future. But due to the type of ecosystem has a tendency to estuary ecosystem at the lower reach of Juoshuei river basin, SIAM is more unsuitable for evaluating at the reach. The correlation between each index is not notable, so we suggest seeking other assessment method as comparative environmental standards.
