Abstract:: Litter layer plays a very important role in forest ecosystem function. This study, in the northern mountain of Hebei Province, collected three typical forests litter, and analyzed their reserves and water-holding characteristics. The results showed that: the reserves of the three forest types of semi-decomposed litter layer are greater than that of the undecomposed layer; maximum water holding capacity of litter sum: the mixed forest of Pinus tabulaeformis and Quercus mongolica (155.31 t/hm²)>the mixed forest of Populus davidiana and Betula albosinensis (105.62 t/hm²)>the mixed forest of Larix kaempferi and Betula albosinensis (88.17 t/hm²); effectively storing greater than the amount of semi-decomposed layer is not decomposed layer, the following order: the mixed forest of Pinus tabulaeformis and Quercus mongolica(128.15 t/hm²)>the mixed forest of Populus davidiana and Betula albosinensis (82.27 t/hm²)>the mixed forest of Larix kaempferi and Betula albosinensis (69.22 t/hm²). Total effective capacity is for: the mixed forest of Pinus tabulaeformis and Quercus mongolica (132.01 t/hm²)>the mixed forest of Populus davidiana and Betula albosinensis (89.39 t/hm²)>the mixed forest of Larix kaempferi and Betula albosinensis (74.95 t/hm²). Holding capacity of litter layers and the soaking time were very good logarithmic relationship. In summary, the mixed forest of Pinus tabulaeformis and Quercus mongolica are the best for soil and water conservation.
