［Objective］ The rainfall redistribution characteristics of different shrub canopies in the western semiarid area of Heilongjiang Province were analyzed to provide a theoretical basis for selection of economically valuable shrub species that are conducive to water conservation in semi-arid regions. ［Methods］ Six economic shrubs with development potential in western Heilongjiang Province， namely Corylus heterophylla， Lycium chinense， Hippophae rhamnoides， Prunus tomentosa， Eleutherococcus senticosus， and Rosa davurica， were used as research objects. Fifteen rainfall events from June to September 2023 were monitored to compare and analyze the rainfall redistribution characteristics of the six shrubs and their influencing factors. ［Results］ Significant differences （p<0.05） were observed in rainfall redistribution among the six shrub canopies， with over 70% of the rainfall falling as throughfall. The average throughfall， stemflow， and canopy interception rates were 71.47%—91.16% （82.14%）， 2.31%—7.46% （4.40%）， and 6.56%—23.41% （13.65%）， respectively. P. tomentosa had the highest canopy interception rate， followed by H. rhamnoides， C. heterophylla， R. davurica， E. senticosus， and L. chinense. Rainfall amount was the key meteorological factor influencing the rainfall redistribution process. The throughfall， stemflow， and canopy interception of the six shrubs showed a significant positive linear correlation with external rainfall （p<0.01）， whereas the throughfall， stemflow， and interception rates exhibited a logarithmic relationship with the external rainfall. Correlation analysis among meteorological factors， stand characteristics， and canopy interception capacity indicated that the interception rate was positively correlated with temperature （p<0.05） and negatively correlated with wind speed （p<0.01）. Except for the non-significant correlation between branch number and throughfall rate， other stand characteristics showed significant positive correlations with stemflow and canopy interception rates and significant negative correlations with throughfall rate. ［Conclusion］ There were differences in rainfall redistribution among the different shrubs. P. tomentosa， C. heterophylla， and H. rhamnoides had relatively high interception and stem flow rates， which are advantageous for reducing rainwater splash erosion and conserving water. L. chinense， E. senticosus， and R. davurica had high throughfall rates， which are advantageous for increasing the effective utilization of water under the canopy. Overall， meteorological factors and stand characteristics play important roles in shrub canopy interception processes.
