title: [Soil hydro-physical properties under broadleaved Korean pine and dark coniferous forests on northern slope of Changbai Mountains].
abstract: The measurement of soil hydro-physical properties under broadleaved Korean pine and dark coniferous forests on the northern slope of Changbai Mountains showed that under these two forest types, soil bulk density and porosity had the same variation trend with increasing soil depth, i. e. , bulk density and capillary porosity increased, while total porosity and non-capillary porosity decreased. The average bulk density, total porosity, capillary porosity and non-capillary porosity in 0-100 cm soil layer were 1. 41 g x cm(-3), 52. 31% , 46. 11% and 6. 20% under broadleaved Korean pine forest, and 0. 98 g x cm(-3) , 50. 65% , 40. 32% , 10. 33% under dark coniferous forest, respectively. Owing to the differences in soil hydro-physical properties, the water storage capacity in 0-100 cm soil layer was 619. 89 t x hm(-2) under broadleaved Korean pine forest, but 1 033.05 t X hm(-2) under dark coniferous forest. For these two forests, their soil water characteristic curves were consistent with the general one.
