On the edge of the Tengger Desert in northern China, revegetation has changed the landscape from moving dunes to stabilized dunes covered by shrubs, which further modifies the pattern of rainfall redistribution. To study rainfall interception loss by shrubs and its relationship to rainfall properties and crown structure, throughfalls passing through crowns of Artemisia ordosicaKrash. and Caragana korshinskiiKom. were measured using nine PVC cups under the canopy of each of the two shrubs during 73 rain events over a three-year period, with total rainfall of 260.9 mm. Interception losses of gross rainfall by A. ordosica and C. korshinskii account for 15% and 27% of the total on a crown area basis, and 6% and 11% on a ground area basis, respectively. Individual throughfall (T) and interception (I) were significantly related to rainfall amount (P_g), duration (D), and intensity (R). Ratios of throughfall to rainfall (T/P_g) and interception to rainfall (I/P_g) were not only significantly related to P_g, D, and R, but also to shrub species, and interactions of species with crown volume (C_v) and leaf area index (LAI). Under most rain events, interceptions by C. korshinskii with greater C_v and LAI were significantly higher than those by A. ordosica, and more rainfall interception occurred at locations closer to the stems of the two shrubs. For C. korshinskii, I/P_g, had a significant positive linear relation with C_v and LAI, while T/P_g had a significant negative linear relation with them. C_v has a greater influence on T/P_g and I/P_gthan does LAI. Using a regression method, canopy water storage capacities are estimated to be 0.52 and 0.68 mm, and free throughfall coefficient to be 0.62 and 0.47 for A. ordosicaand C. korshinskii, respectively.
