Decomposition dynamics of the fitters from three dominant plant species in Taxodium ascendens forest in Dalian Lake of Shanghai
摘要
Abstract
By using litterbag method, a 190-day incubation experiment was conducted to study the decomposition rates and the release dynamics of C, N, and P of the litters from three dominant species (Taxodium ascendens, Echinochloa cruspavonis, and Alopecurus japonicas) in T. ascendens forest in Dalian Lake, Shanghai. In the meantime, the quantity of the litters in the T. ascendens forest was measured by using collection container. In the forest, the annual production of T. ascendens litters was 5.70 t · hm-2, being the primary source of the litters in the forest. The litter decomposition rate (dry mass loss rate) was in the order of A. japonicus > E. cruspavonis > T. ascendens. During the experimental period, the C content of the three species litters decreased significantly, while the N and P contents had somewhat increase in T. ascendens litters but not in E. cruspavonis and A. japonicus litters.关键词
