Abstract	Due to its rapid growth and high rate of spread,Phyllostachyspubescenscan suppress other species, eventually leading to pure P. pubescensforests.Research on the patterns of litter decomposition and nutrient release from P. pubescensacross stand mixturesare helpful to understandthedecomposition and nutrient dynamicsduring the invasion process.However, little is known for unmanaged conditions at high elevations. Therefore, westudiedthedecompositionoffour litter compositions comprised of different combinationsof P. pubescens andCunninghamialanceolatafoliagefor one yearto explore the pattern of litter decomposition and nutrient releaseat the Daiyun Mountain National Nature Reserve. The results show that: (1)the litter decomposed faster with ahigher proportion of P. pubescens based on Olson's decay model;(2)the remaining litter compositions followed a trigonometric function model better than Olson's decay modeland fluctuated periodically in tandem with changing temperature and precipitation;(3) the litter mixture decompositions did not support the biomass-ratio hypothesis test; and (4) there weresignificant binomial, power and exponential relationships between initial concentration and final amounts remaining after 1 year decomposition for C, N and P. The correlations between litter decomposition and nutrient releasesweresignificant.The results may be used to explain the rapid spread of P. pubescensand to guide the natural management of plantations.
