摘要: 对枫香人工林枯落物和土壤养分季节变化进行研究。结果表明:不同季节枯落物的养分大量元素含量大小顺序是夏季>秋季>冬季>春季,含量范围是25.055~37.115 g/kg。土壤中A层大量元素含量从春季开始递减,至夏季达到最低值,秋季有所回升;B层土壤养分含量季节变化呈双峰型,但变化幅度不大.说明土壤养分含量随着深度的增加受到枯落物的影响越小,其土壤养分含量越稳定。A层土壤较容易受到枯落物季节性的影响,微量元素季节变化呈波浪型;B层土壤微量元素含量一年中始终呈现增加趋势。

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
