Abstract  

Precipitation plays an important role for the growth and sand fixing of fixing-sand shrubs in Minqin oasis fringe. A field observation was conducted to measure precipitation permeating canopies of three shrubs and the precipitation interception loss by canopies of the three shrubs during different rainfall events, and relationships between precipitation permeating canopies of three shrubs and precipitation, the precipitation interception loss by canopies of the three shrubs and precipitation, and precipitation interception ratio and precipitation intensity were analyzed, and the different influences of the three shrubs on canopy precipitation interception loss were compared. The results showed that, the interception loss in the canopies among the three shrubs had significant differences during individual rainfall events; the maximum interception loss for the canopies of Haloxylon ammodendron, Tamarix ramosissima, normal Nitraria tangutorum and degraded N. tangutorum were 0.6 mm, 0.6 mm, 0.4 mm, 0.3 mm, respectively; while the maximum interception capacity were 0.8 mm, 0.8 mm 0.5 mm, 0.2 mm, respectively; the estimated total canopy interception losses for the communities of the three shrubs were 44 mm, 88 mm and 32 mm, respectively, which were 16.6%, 33.1% and 12.0% of the total 255.3 mm rainfall during the two years, respectively; the proportion of interception loss to gross rainfall for H. ammodendron and T. ramosissima decreased with the rainfall intensity when rainfall intensity was less than 0.8 mm·h-1, and tended to remain constant at 0.2-0.3 for H. ammodendron and 0.3-0.4 for T. ramosissima when the rainfall intensity was more than 0.8 mm·h-1; the proportion of interception loss to gross rainfall decreased with the rainfall intensity if rainfall intensity was less than 0.5 mm·h-1, and tended to keep constant at about 0.1-0.2 for the normal N. tangutorum when the rainfall intensity was over 0.5 mm·h-1; the constant interception proportion for the degraded N. tangutorum was  0.05-0.1 for when the rainfall intensity was more than 0.4 mm·h-1.
