Abstract: Studies on the accumulation and distribution of nutrient elements in Phyllostachy spubescens community of South Fujian show that the total accumultaion amount of N,P,Si,K, Ca and Mg is respectively 13.96,2.89,70.04,41.29,5.84 and 3.63g·m-2. Indifferent parts of Phyllostachys pubescens, leaf has the highest amount of these elements,and whip is the second. Among these 6 elements, Si has the highest concentration,1.60% on average, and K is the second,0.55% on average. The content of Si is thehighest in leaves, being 15.60g·m-2, and that of N and K is the highest in stems, beingrespectively 6.58 and 20.67g·m-2. The roots also contain a higher content of Si, being 11.45g·m-2. The high content of Si in leaves indicate that bamboo is a transitional typefrom woody plant (which has a lower content of Si) to grass (which contains more Si).

Key words: Phyllostachys pubescens community, Nutrient element, Element content
