Abstract: The paper deals with the production and nutrient contents of litter of Dinghu Shan Mountain broad-leaved evergreen forest and coniferous forest from the period of 1983—1990.The annual litterfall is, broad-leaved evergreen forest 9.056t·ha-1·yr-1;coniferous forest 2.695t·ha-1·Yr-1. Those fractions as leaf, branch flower and fruit vary in these two types of forests.The main total nutrient contents(N, P, K, Ca, Mg) in litter for broad-leaved forest are much higher than those for coniferous forest. The annual litterfall in broad-leaved evergreen forest is less than those in tropical rain forest, but higher than those in temperate deciduous broad-leaved forest. This leads to such an implication that the litterfall is highly related to zonal climatic patterns. The alternation of high and low litterfall was found during this 8 year period. Compared with coniferous forest, broad-leaved forest offers more in the aspect of soil erosion control and soil improvement due to its high litterfall, rapid decomposition and high nutrient contents in litter.
