The litter storage,the water-holding capacities and soil hydrology physical properties in the 5 main forest type in south part of Daxing'anling were studied.The results showed that the litter storage were 12.35~48.46 t/hm2,the litter storage of conifers is higher than that of broadleaf forest,the semi-decomposed litter storage of each forest stand is 1.3 times higher than that of nondecomposed;the max water-holding percentage ranged 565.66%~676.36%,averaged 617.13%;the max water-hoolding capacities ranged 92.70~319.96 t/hm2,averaged 193.68 t/hm2,the highest one is grass-larix,the lowest one is betula;the max water-holding capacities of the semi-decomposed is 1.3~6.1 times higher than that of nondecomposed;the max water-holding capacities of conifers is higher than that of broadleaf forest;the lowest one is that of broadleaf forest.the maximum interception rate ranged 416.55%~545.61%,averaged 454.12%;the maximum interception amount varied 71.5~200.27 t/hm2,averaged 125.97 t/hm2;the modified interception rate changed 327.28%~418.99%,averaged 356.52%,the modified interception amount changed 57.60~152.27 t/hm2,averaged 96.91t/hm2;there are the same order about soil total porosity percent and capillary pore percent;the non-capillary pore percent of betula is highest for 14.52%,the least one is grass-larix for 7.09%,the maximum moisture content and capillary moisture content of oak is highest for 5 682.60 t/hm2 and 7 162.80 t/hm2,the lowest is grass-larix for 2 683.60 t/hm2 and 3 817.00 t/hm2.
