| The canopy interception, canopy rainfall interception and influencing factors of monolayer and double-layer structure plants in Kunming gardens were studied in this paper. The results showed that: (1) Rainfall events occurred 42 times during the observation period, and the total rainfall reached 229.6 mm, effective rainfall reached 22 times. The rainfall was classified by standard of 1 h, including small rain (<2.5 mm) for 12 times, moderate (2.5-8.0 mm) for 9 times, heavy rain (8.0-16.0 mm) for 1 time. (2) The better interception plant of conifers was Sabina, the worse was Yunnan pine. The better interception monolayer arbor of broadleaf plants was Mountain magnolia, the worse was Osmanthus. The better interception monolayer shrub of broadleaf plants was Azalea, the worse was Sasanqua. The better interception of doublelayer plants group were Palm and Musella lasiocarpa, the worse were Yunnan Pu and Lam pointed leaf clover. (3) The mainly influencing factors of canopy interception were crown shape of trees, density of foliages, planting patterns of garden plants, rainfall outside the canopy and rainfall intensity. |
