Abstract: In this paper, several major parameters (such as CODCr, DO, NH3 -N, Fe and Mn etc.) in Nanning Zhupai Creek were used to correlate with the black-odour index. The results showed that CODCr, NH3 -N, DO, Fe, Mn were the major factors to affect the black-odour index. Based on a set of data, a predict model for the black-odour index in Zhupai Creek was developed, i.e.,
I=0.050 3［CODCr］＋0.257 6［NH3 -N］-2.304 9［DO］＋1.239 4［Fe］＋2.770 0［Mn］＋14.407 8.
The above model provides not only a good evaluation tool for the black-odour level in Zhupai Creek, but also the theoretical basis for building early warning monitoring system in the black-odor in Nanninig urban rivers.

Key words: evaluation model, Zhupai Creek, river regulation, black-odour, evaluation model, Zhupai Creek, river regulation
