This paper reveals
the variations of S concentration among the leaf surface and other organs of variousplant
species, and presents the distribution natures of S storage in the evergreen broad-leaved
forest vege-tation in Hangzhou on the basis of the tested data concerning plant S contents. The
result was that theS concentrations on the tree leaf surfaces varied with the testing time and
plant species. The range of Scontents 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 showedthat there was an apical
dominance of S distribution. The total amount of S storage in the vegetation wasas 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
verticaldistribution per unit height (m), root stratum (0 - 0.20 m of soil depth)> stratum nearby
the ground surface(0 - 0.5m) > canopy (4.0- 9.5m) > trunk stratum (2.0- 4.0m).
