- Abstract:
- Soil physical properties of four main land uses (cropland, orchard, woodland and grassland) were investigated on the base of field experiments and indoor measurement from a typical watershed named Luoyugou in the third sub-region of the Loess Plateau. The main findings included: (1) The average soil moisture content was (15.76±0.34)% in the watershed, but it existed obvious differences with regard to different land uses, and presented cropland>woodland>orchard>grassland; (2) The average soil bulk density in the watershed was (1.421±0.034)g/cm3, and tended to increase with soil depth increasing, generally taking on the distribution of woodland>cropland>orchard>grassland, which was similar to the above; (3) Soil porosities of the four land uses had negative correlations with soil bulk densities, besides the total porosity, capillary porosity and non-capillary porosity in each land use all presented woodland>cropland>grassland>orchard; (4) There were some differences on water storage capacity, that is, woodland and cropland took on better performances than grassland and orchard. It should be noticed that in recent years large scale sloping fields were converted to plane terraces, which produced huge influences on soil and water conservation in the cropland, and it was proved to some extent in this paper that cropland had high soil moisture and water storage capacity.
