Abstract: The productions, seasonal dynamics, macronutrient contents and decomposition rates of the litterfalls of four typical stands,e.g.,Pinus massoniana plantation,secondary evergreen broadleaved forest,Acacia mangium plantation and Schima superba-Acacia mangium plantation at the scenic Baiyunshan of Guangzhou were studied. The litterfall productions of four stands in 1998 were 8.34, 6.77, 6.31 and 11.54 t穐m^-2, respectively. The seasonal dynamics of litterfall amounts demonstrated the single-peak model with the peak period in June and July.The total amounts of macronutrients returned to the forest land by means of litters in the four stands in1998 were 26.30, 69.81, 54.9 and 152.24 kg穐m^-2, respectively. The annual decomposition rates of the litterfalls were 24.4%, 53.4%, 52.4% and 57.4%.

Key words: Baiyunshand Mountain, Forest stands, Litterfalls, eco-environmental quality, remote sensing ecological index, principal component ana-lysis, Nanweng River Nature Reserve
