This research outcome can provide guidance for the selection of garden planting, and will assist to alleviate urban water shortages and promote the construction of sponge cities. The aim of this study is to investigate the leaf interception capacities(LIC)of 16 evergreen broad-leaved plants in the Guanzhong of Shaanxi. The leaves of the evergreen broad-leaved plants were collected and analyzed based on the proposed method by submerging leaves to obtain the surface water storage amount and the maximum water storage amount that can be used to measure the LIC of single leave and explore its relationships with the factors of characteristics. The results show that leaf morphological factors(leaf area, leaf thickness, leaf length, and leaf width)and leaf functional factors such as leaf dry matter content(LDMC)and specific leaf weight(SLA)have the great influence on LIC. Leaf morphological factors and SLA are positively correlated with LIC, while LDMC is negatively correlated with LIC. Compared with the functional factors, leaf morphological factors have the greater effect, and the relationship between leaf morphological factors and LIC can be described by a composition function. According to this study, it is concluded that the plant species with larger leaf area, smaller LDMC and medium SLA have the highest LIC.
