研究了海南麻竹林凋落物量及其养分动态.结果表明:麻竹林凋落物全年总量为6 862.8 kg·hm-2.N、P、K、Ca、Mg的年归还量分别为74.847、3.264、25.921、45.924、11.902kg·hm-2,大小顺序为:N＞Ca＞K＞Mg＞P,养分总的年归还量是161.858kg·hm-2·a-1.凋落物分解失重率达95%的分解期为11.59个月,每年产生的凋落物全部归还于土壤.
The litter and nutrient dynamics of Dendrocalamus latiflorus forest in Hainan were studied. The results showed that the total litter biomass all over the year was 6862.8kg·hm -2. The nutrient of N、P、K、Ca、Mg that yearly returned to the soil were 74.847, 3.264, 25.921,45.924 and 11.902 kg·hm -2 respectively. The descending order was N>Ca>K>Mg>P. Totally returned nutrient amounted to 161.858 kg·hm -2·a -1. The duration of 95% decomposition of the litter was 11.59 months. The litter produced per year was completely returned to the soil in one year.
