Abstract: This thesis is a preliminary study of the litter in Aneurolepidium chinense meadow. The dynam cs of the litter’s decomposition, accumulation and nutrient contents are examined.Based on the collected data, the simulation models for decomposition and accumulation of the litter have been built by computer analysis.Disappearance rate is 0.4065g/g·a. The seasonal change of the rate of lost weight is in accord with the Logistic curve. The decomposition activity is very strong from May to September. The lost weight of litter during this period makes up 90 per cent of the annual lost weight. Decomposition action nearly ceases in winter. Under the present condition of Aneurolepidium chinense meadow, it will take about 7—8 years to approach a steady accumulation quantity of 95 per cent. The maximum accumulation quantity is about 572g/m2.The contents of chemical composition continuouly declined in comparison with the early stage of the decomposition process. The loss of N, P and K is relatively faster than that of the other elements. Cellulose decomposes more slowly. The order of loss of every chemical composition is K>P>N>Na>Ca>Mg> Fe>cellulose.
