用雨滴谱仪测定了三种热带种植园树种冠层对自然降雨和模拟降雨雨滴谱的修正。与以前发表的结果相反，物种之间的修改程度存在很大差异。测得的中位体积滴直径分别为2.3，2.8和4.2毫米加勒比松，赤桉，柚木，分别。不同物种的特征滴谱与强度约为50、100和3000 mm h-1（基本上是无限大）的降雨的相应滴谱相当。camaldulensis和T.大，分别。这些结果对易受土壤侵蚀影响的地区选择最佳树种具有一定的意义。
The modification of the drop size spectra of natural and simulated rainfall by the canopies of three tropical plantation tree species was measured using a disdrometer. Contrary to previously published results, large differences were found between species in the degrees of modification. The median-volume drop diameters measured were 2.3, 2.8, and 4.2 mm for Pinus caribaea, Eucalyptus camaldulensis, and Tectona grandis, respectively. The characteristic drip spectra for the different species are equivalent to the corresponding drop size spectra for rainfall with approximate intensities of 50, 100, and 3000 mm h-1 (essentially infinite) for P. caribaea, E. camaldulensis, and T. grandis, respectively. These results have implications for the choice of the best tree species for areas susceptible to soil erosion.
