摘要
采用浸泡法和人工降雨测定甘肃南部白龙江4种不同灌丛最大截留量,初步探索叶片截留的影响因子.结果表明:(1)同一植物叶片采用人工降雨法其叶片最大截留量始终大于浸泡法,人工降雨法叶片最大截留量较浸泡法多5.84%~12.41%.(2)同一地区不同植物截留能力不同,白龙江4种主要灌丛叶片的最大截留能力从大到小依次是聚花荚蒾>绣线菊>箭竹>甘肃柳,最大截留量、基径、株高、叶面积呈正相关性,且截留能力越大,相关性越显著.
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 interception 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 interception capacity,the more significant the correlation was.
