文摘内容 This paper reveals the variations of S concentration among the leaf surface and other organs of various plant species,and presents the distribution natures of S storage in the evergreen broad-leaved forest vegetation in Hangzhou on the basis of the tested data concerning plant S contents.The result was that the S concentrations on the tree leaf surfaces varied with the testing time and plant species.The range of S contents in various organs of a plant was 2.086-4.245 S g kg^-1,varying with plant species in this forest.The S content in the leaves was the highest,followed by that in the branches,trunks and roots,which showed that there was an apical dominance of S distribution.The total amount of S storage in the vegetatioin was as large as 349.97 S kg ha ^-1,The S distribution in this vegetation had two characteristics as follows:1)for the vegetation layers,arbor layer>renewal layer>herb layer>shrub layer;and 2) for the vertical distribution per unit height(m),root stratum(0-0.20m of soil depth)>stratum nearby the ground surface (0-0.5m)>canopy(4.0-9.5m)>trunk stratum (2.0-4.0m)。
