对海岸带农林复合系统中的池杉（Taxodiumascendens）、青秆竹（Bambusalongiflora）、水稻（O-ryzasativa）、甘蔗（Saccharumofficinarum）等主要植物种类的生物量与元素组成进行研究．结果表明：6年生池杉林分、青秆竹林分均是叶的养分元素含量最大，树干的最小；其养分元素积累量分别为2689.481和3297．442kg/hm2，其养分元素积累量排序分别为N＞Ca＞Mg＞K＞Cl＞Na＞P、K＞Cl＞N＞Mg＞Ga＞P＞Na；水稻（杂优）、甘蔗的养分元素积累量分别为1186．083、1161.630kg/hm2，其养分元素积累量排序分别为K＞N＞Mg＞Cl＞Na＞Ca＞P,K＞N＞Cl＞Mg＞Ca＞Na＞P，两者均是K、N的贮量较大，P的较小．4个物种尤以禾本科植物更适宜于泥质含K丰富岸段的生长．
The biomass and elemental composition of major plant species Taxodium ascendens, Bambousongiflora, O-ryzasativa and Saccharum officinaarum in coastal agroforestry systems were studied. The results showed that the 6-year-old larch plantation and the green bamboo plantation had the highest content of nutrient elements and the smallest of tree trunks. The nutrient element accumulation was 2689.481 and 3297.442kg / hm2, respectively. The order of nutrient element accumulation was N The accumulation of nutrient elements in rice (hybrid) and sugarcane were 1186.083, 1161.630 kg / hm2, respectively, The order of nutrient accumulation was K> N> Mg> Cl> Na> Ca> P, K> N> Cl> Mg> Ca> Na> P, Smaller. Four species, especially gramineous plants, are more suitable for the growth of muddy K-rich shore sections.
