摘要
The distribution of soil Cs-137 in relation to selected soil and landform properties was studied across a 16 ha hillslope hollow in the Hunter valley, New South Wales, Australia. The hillslope was used as grazing for cattle. Caesium-137 was not significantly related to the amount of sand, silt, or clay, the bulk density, the organic matter content, the slope angle or the relative distance downslope. However, Cs-137 was significantly related to the thickness of the soil A horizon Spatial variations in Cs-137 were compared with topographic units and a six-element hillslope model, but there was little correspondence. It was though that the effects of microtopograhy could have masked potential interrelationships between Cs-137 and broader scale landform parameters.
