Dynamics of Litterfall at Different Altitudes in Moso Bamboo Plantations

  • Received Date: 2012-08-31
  • To assess the effects of altitude on litterfall dynamics and changes of periodic rules on moso bamboo (Phyllostachys edulis), the seasonal and annual dynamics at different altitudes (350 m and 650 m) from June 2008 to December 2011 in Mount Dagangshan, Jiangxi Province, were studied. The results showed that: (1) The annual average litter production of moso bamboo plantations at different altitudes during the period was estimated to be (1 695.05±87.23) kg·hm-2. The ANOVA analysis suggested that the influence of elevation to litter production was not significant. (2) There existed periodic rules in on-year and off-year, with a length of about 12 months and dividing point of every June. Compared with on-year, the seasonal variation of litter production in off-year was more remarkable. Litter production in spring and summer contributed 68.71%-72.39% of the total in off-year. (3) The moso bamboo plantations at high elevation site were more seriously affected by the 2008’s ice storm disaster compared with that of the low elevation site. Based on the study, it could be concluded that by June, 2010, the moso bamboo plantations may have recovered to be normal.
