Soil bulk density

soil porosity

soil moisture capacity and water storage characteristics for six main forest types in Wuyishan Scenery District were studied.Results are as follows.(1)The soil bulk density in the top 60 cm followed the order of: chinese fir forests> masson pine forests> shrubs> mixed forest>moso bamboo forests> broadleaf forest.(2)The total porosity and maximum water-holding capacity were:broadleaf forest> moso bamboo forests>mixed forests> shrubs> masson pine forests> chinese fir forests;and the capillary porosity and field moisture capacity were: Moso bamboo forests> broadleaf forests> mixed forests > shrubs> masson pine forests> chinese fir forests; the soil noncapillary porosity was broadleaf forests> mixed forests > shrubs > masson pine forests> chinese fir forests> moso bamboo forests; the soil capillary waterholding was moso bamboo forests> broadleaf forests> shrubs> mixed forests > masson pine forests> chinese fir forests.(3)In the layer of 0-60cm

the order of soil total storage capacity was broadleaf forests> moso bamboo forests> mixed forests> shrubs> masson pine forests> chinese fir forests.The storage volumetric capacity of moso bamboo forests was the largest

but its transmission volumetric capacity was the smallest.Given the same site condition

the soil physical characteristics of the broadleaf forest were superior to those of the others and therefore provided the best function of soil and water conservation.
