Based on the methods of double-rings and core sampler

the primitive characteristics of water storage capacity and permeability of undisturbed typical black soil(the prairie meadow and the Populus davidiana secondary forests in Keshan farm

Heilongjiang province) were researched.The results suggested that

the prairie meadow and the Populus davidiana secondary forests had better capability of water storage and permeability compared with abandoned land and fallow land.Within the depth of 1m

the saturated water storage of prairie meadow(5 271.14 t/hm2) was higher than the Populus davidiana secondary forests(4 945.91 t/hm2)

but the non-capacity water capacity were closer

respectively 402.20 t/hm2 and 425.40 t/hm2;the soil initial permeability and solid permeability rate of the prairie meadow were 8.5 mm/min and 7.5 mm/min

and the latter are accordingly 1.2 mm/min and 3.2 mm/min

the Populus davidiana secondary forests had the better permeability during the whole process.Above all

this result would provide more important primitive characteristics of water storage capacity and permeability for undisturbed typical black soil scientifically.
