Abstract: In this paper, the litter decomposition rates of several plants have been studied, the results showed that the litter decomposition rates were different with different plants. The ratio of weight losses of the litter of Robinia pseudoacacia, Armeniaca vulgaris var. ansu, Platycladus orientalis, Acer truncatum and Cotinus coggygria var. cinenea for one year were 54%, 64%, 78%, 73% and 65%, respectively. According to the exponential decay model, the estimated litter decomposition rates of Robinia pseudoacacia, Armeniaca vulgaris var. ansu, Platycladus orientalis, Acer truncatum and Cotinus coggygria var, cinenea were 0.490g/(g·a),0.597g/(g·a),0.990g/ (g·a), 0.800g/(g·a) and 0.662g/(g·a) per year, respevtively. The chemical component analysis of the litters showed that the weight loss of the litters was due to the losses of gross fat, soluble sugar, tanin and organic carbon initially. The ratio of the carbon content and the hitrogen content of the litters decreased with the passage of time during the annual decomposing process.
