Abstract: Study is conducted on the seasonal changes of the nutrient of litter-soil of artifical forest of Liquidambar formosana.The result shows that the order of the quantity of micro-elements of litter storey in seasonsis summer>autumn>winter>spring, and the content is the scope of 25.055 ～37.115 g·kg-1.The content of the macro-elements decreases in Layer A in spring andreaches the nadir in summer, and then starts to rebound in autumn. Soil nutrient content changes in Layer B is undee. The impact of the litter soil on the soil nutrient content becomes smaller with the depth of soil and the soil nutrientbecomes more stable. With the impact in seasons of litter storey, Layer A's micro-element change is undee. Layer B's micro-element change shows upward trend in the year.

Key words: artifical forest of Liquidambar formosana, litter, soil, seasonal changes of nutrient
