摘　　要：对合肥市大蜀山森林公园森林凋落物的现存量与其组分进行测定和估算,初步得出大蜀山森林凋落物的基本特征。大蜀山森林凋落物现存量初步估算为4 317.5 t,有机碳、N、P、K、Ca、Mg的含量分别为4 643.51、108.04、10.72、48.26、156.75、23.96 kg/hm2,可见凋落物是森林重要的营养库之一。Standing stock and component of the litter fall in Dashushan forest park was measured and estimated. The standing stock of litter fall in forest park was 4 317.5 t, and the amount of organic C, N, P, K, Ca and Mg contents were 4 643.51 kg/hm^2, 108.04 kg/hm^2, 10.72 kg/hm^2, 48.26 kg/hm^2, 156.75 kg/hm^2 and 23.96 kg/hm^2,respectively, which showed that the litter fall of the forest park was an important nutrient storeroom.
