A preliminary study on hydrological effects of litter layer and soil layer in natural Syzygium aromaticum forests was carried out in the five different densities (784, 1 024, 1 210, 1 616, 1 872 per/hm2)in Songshan mountain of Beijing. The results showed that the total storage capacity, the maximum water holding rate of litter and the maximum water holding capacity increased with the increase of density; the total storage capacity of litter was about 13.19~31.66 t/hm2, the modified interception capacity of litter was about 32.71~79.77 t/hm2; the maximum water holding capacity of litter was about 50.76~119.29 t/hm2 and had significant logarithmic correlation with immersion time(R > 0.86); the maximum water holding rate of litter was about 385.72%~507.16% and had power function relationship with immersion time(R > 0.99); the soil bulk density increased with the increase of depth of soil layer in the same density. The total soil porosity increased firstly and then decreased with the density. The initial infiltration rates of soil varied between 37.50 mm/min and 54.55 mm/min. The infiltration rate had power function correlation with infiltration fit time(R > 0.99). Syzygium aromaticum forest with medium density had stronger water conservation function.
