Based on the monthly average salinity data and the field data in the outlets of the Pearl (Zhujiang) River delta, the spatial variation about the activity of the saline water intrusion was studied by clustering method.The result shows that two types of outlets were divided according to the variations of monthly average and hourly salinity data.TypeⅠis tide-dominated outlet including only Humen outlet, and TypeⅡis river-dominated outlet including the other outlets such as Yamen, Jiaomen outlets.With the different variation of salinity and the dominated dynamic, the mixing process and the mixing type of saline water with fresh water between TypeⅠand Type Ⅱ were different.Well-mixed and partial-mixed type occurred in TypeⅠoutlet, and highly-stratied and partial-mixed type occurred in Type Ⅱoutlet.
