英文摘要	Canopy interception is an important part of the water cycle, which ultimately affects the water budget by dissipating in the form of evaporation. The canopy interception rate (I) is a commonly used index to describe interception but is dynamic with rainfall conditions, which reduces comparability of results among different sites or vegetation types. While canopy storage capacity (I-0) is relatively stable but is rarely used in previous studies. This study analyzed data from the existing literature to obtain an understanding of the measured and modeled values of I-0 for the main vegetation types in China, then comprehensively assess the species and spatial differences of canopy interception capacity. The results showed that trees dominate intercepted precipitation in the southern region, while shrubs dominate intercepted precipitation in the north. The comprehensive interception capacity of vegetation in the southern region was generally higher than that in the north; however, changes in interception related to regional forestation policies may reverse this trend. The I value of single-species forest stand canopies, located primarily in southern humid regions, is generally larger than that of shrubs, which are generally located in northern arid regions. Within a given area, the actual I value of shrubs was greater than that of single-species forest stand, indicating shrubs have a greater influence on the local water cycle than trees where both exist. Variations in I and I-0 were sensitive to meteorological factors and stand structure, which led to inconsistent results when evaluating vegetation canopy interception. Overall, this study quantifies and reviews studies on vegetation canopy interception in China and suggests that the current structural characteristics of the northern shrub land may be unfavorable for water conservation in the northern arid region. How to adjust vegetation to maintain regional water supply and demand balance is a problem that needs to be solved in the future.
