摘要
对园林绿化树种林冠截留降水作用进行研究,探讨不同绿化树种的林冠对降雨分配的影响,可以为进一步研究城市植被对海绵城市的贡献提供基础数据。通过对白蜡、枇杷和女贞人工林天然降雨条件下穿透降雨和树干径流等数据的统计分析,了解3个树种之间林冠截留降水差异。结果表明:白蜡、枇杷和女贞3个树种的林冠截留和树干径流过程都与林外降雨呈正相关,随着林外降雨强度的变化而变化。进一步证明了通过树干径流效果选择树种的可行性和重要性,为以后树干径流相关科研工作的开展提供了参考依据。
To Study the canopy rainfall interception of landscaping tree species, explore the influence of rainfall distribution of different landscaping tree species, provide basic data for further study on the urban vegetation＇ s contribution to the sponge city. This paper reveals the difference rainfall interception canopy among the tree species by statistical analysis of the rainfall and runoff data under the conditions of man-made forest natural rain. The results show that： the rainfall and runoff data of tile three tree species all positively correlated to the rainfall, change according to the rainfall intensity. Further proves the feasibility of choose species by the effect of trunk runoff, provides reference frame for related research work of the trunk runoff.
