Abstract:By taking typical forest communities in the Liaoheyuan Nature Reserve as an object, litter storage and water-holding were studed. The results show that:(1) The variation range of litter layer reserves was about 7.92~15.56 t/hm2, the litter layer total storage capacity in the 60 a Pinus tabulaeformis was the largest, and Larix kaempferi was the least;(2) The largest water-holding rate was about 164.12%~333.06% and the order was Populus davidiana×Betula platyphylla > Larix kaempferi > Pinus tabulaeformis(50 a) > Pinus tabulaeformis(60 a) > Pinus tabulaeformis(40 a);(3) The maximum water-holding rate ranged from 21.31 t/hm2 to 38.13 t/hm2 and the order was Populus davidiana×Betula platyphyll > Pinus tabulaeformis(60 a) > Pinus tabulaeformis(50 a) > Larix kaempferi > Pinu stabulaeformis(40 a);(4) By statistic analyse, the equation between water-holding capacity of undecomposed litter and semi-decomposed one and immersion time obeyed logarithmic regression relationship(R>0.87), while the water-holding speed rate and immersion time obeyed power function relationship(R>0.87).
