Abstract

Preferential flow is common phenomena in soil,and has significant influence to soil water movement.The soil preferential flow under three typical vegetations was researched by using brilliant blue dye tracer method in field,in order to research the forest conserving water resources deeply.The results showed that the preferential flow exist in all soils under three typical vegetation in upper reach of Minjiang River,and the complex degrees of preferential flow is different for each soil due the deference of vegetations,elevations,soil formation processes,action of roots and soil animals.The dye area ratios reflected the distribution of infiltrated water in soil profiles,although most infiltrated water rested within 10 cm nearly soil surface,some water reached the bottom of profiles through the preferential flow channels.The fractals of preferential flow dye profiles were 1.59 to 1.85,and it reflected the complexity of preferential flow channels,the soils under the virgin coniferous fir forest and sub-alpine meadow had high fractals with complex preferential flow channels.The preferential flow brings key influences for knowing hydraulic processes in slope,and is a basis for understanding the hydraulic effects of forest.

Key words： Soil Preferential flow Dye tracer Fractal
