Leaf-Litter Decomposition Dynamic, Carbon Loss and Nutrient Return for Moso Bamboo Forest with Different Litter Mass Accumulation

Abstract:

To provide an important basic knowledge for the biogeochemical cycle of bamboo forest ecosystem, particularly the cycling of global carbon, we studied decomposition dynamics of leaf-litter with different mass accumulation in moso bamboo forest. Our study area located in Miaoshanwu nature reserve, Fuyang, Zhejiang province. Based on the survey, we concluded that: (1) the sequence of remaining mass of leaf-litter with different mass accumulation after 240 days' decomposition from the most to the least was in the following order: 30g (58.53%) > 60g (51.92%) > 90g (48.48%), implying that leaf-litter with more mass accumulation decomposed faster in the unit area. (2)The more accumulated leaf-litter lead to more TOC loss in leaf-litter which will not helpful for TOC increase on surface soil carbon pools. This implying that the faster leaf-litter decomposed, the less TOC increased on surface soil carbon pools in 240 day s' observation. (3)The concentration of N, P, K and Ca showed the similar tendency with initially increasing but decreasing gradually in the following stage and then increasing again in the next stage. And concentration of Mg, Fe, Cu and Zn increased gradually in the period of 0-240 days.
