Abstract: Vineyards in the Taige Canal Valley of Changzhou were chosen for experiment on non-point source pollution.Through monitoring the processes of rainfall,runoff and pollution generation,event mean concentrations (EMCs) were calculated,and by taking into account vieyard management practices,such as fertilization,the characteristics and affecting factors of the runoff pollution therefrom were analyzed.Results show that EMCs were negatively related to mean rainfall intensity on the whole,and varied sharply from event to event.Runoff caused by an event always lagged in phase and its pollutant content varied in concentration with its process.Pollution generation is a complicated process affected by many factors,such as rainfall, rainfall intensity,fertilization and so on.

Key words: vineyard, rainfll-runoff, event mean concentrations(EMSCs), non-point source pollution
