甘肃白龙江亚高山4种主要灌木截留特征研究OA

Soaking method and artificial rainfall were used to determine the maximum interception of 4 different shrubs in Bailong river,southern Gansu Province,and to explore the influential factors of leaf interception.The results showed that:(1)the maximum leaf interception of the same plant using artificial rainfall method was always greater than that using soaking method,and the maximum leaf interception of artificial rainfall method was 5.84％～12.41％more than that using soaking method.(2)The interception ability of different plants in the same area was different.The maximum intercep-tion ability of the leaves of the four main shrub species in Bailong river was in the order of Viburnum glomeratum＞Spiraea salicifolia＞Fargesia spathacea＞Salix fargesii.The maximum interception capacity,base diameter,plant height and leaf area were positively correlated,and the greater the in-terception capacity,the more significant the correlation was.
