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.

由指标相关性讨论可知栖地品质与生物完整性相关性较高(r=0.649)，水质状态与生物完整性相关性则较低(r=0.267)，对於中上游河段部分，建议日后进行河川生态环境调查时可选择简便易用的SIAM模式做为标准；下游近海河段则因河川型态渐转变为河口生态系的型态，故适用於溪流生态系的SIAM在适用性上较差，各指标间相关性并不显著，建议可寻求其他评估模式做为环境品质的判断标准。

It is shown from the study results that (1) SSC has obvious neap-spring and seasonal variations with periods being 14.7 days and 368 days, respectively, on an average, SSC during the spring tide was 2.96 times as much as that during the neap tide, and SSC in winter was twice as much as that in summer;(2) correlation coefficient between daily SSC and tidal range on the same day in a mean neap-spring period of 15 days was 0.86, and correlation coefficients between tidal range and daily SSC with one day and two day lag were 0.99 and 0.93, respectively, which indicates that the effect of tidal range variation on SSC has a one day or two day hysteresis;(3) the monthly mean SSC was negatively correlated with the monthly mean water discharge at the Changjiang River Datong station, especially well with the water discharge with a lag of 19 days.
