- Abstract:
-
The soil of 0-50 cm on the sloping-land with purple soils in Hengyang Basin was studied in 2007. The results showed that: (1) The water content on the sloping-land with purple soils was higher in north-facing slope than those of the corresponding level places in south-facing slope, but there was a contrary tendency in coefficient of variance in the water content on the sloping-land with purple soils in Hengyang Basin; (2) In the same perpendicular space, the sequence of the water content in sloping-land with purple soils in Hengyang Basin was as follows: the lower-slope>the middle-slope>the upper-slope; The sequence of coefficient of variance in the water content in south-facing slope was as follows: the upper-slope>the middle-slope>the lower-slope, and there a contrary tendency in the coefficient of variance in north-facing slope; (3) The water content in sloping-land with purple soils in Hengyang Basin had something to do with the rain in the same period. There was much rain from January to June, but there was little rain from July to December; (4) In the same level space, there was an increasing tendency in the water content with the increasing in the depth in soil, there was an increasing tendency in the coefficient of variance with the increasing in the depth in soil in south-facing slope, and there was a contrary tendency in the coefficient of variance in north-facing slope.In the depth of 10-30 cm, the water content in soil was the stablest.
