Effect of Visitor Trampling on Soil Physio-chemical Properties in Jigongshan National Nature Reserve

Core area, buffer area and control were established according to different visitor trampling in Boerdeng Forest Park of Jigongshan National Nature Reserve, Henan province, and soil samples were collected in different area for determination of physio-chemical properties. The results showed that soil bulk density under serious trampling (1.23 g/cm3) was significantly higher than that under light (1.03 g/cm3) and middle (1.07 g/cm3) ones, whereas soil total porosity (57.5%) were lower than that under light (61.3%) and middle (59.6%) ones. Soil total nitrogen (1.9 g/kg and 1.8 g/kg) and soil organic carbon (19.3 g/kg and 21.2 g/kg) under middle and serious trampling were significantly lower than that under light one (2.2 g/kg and 26.8 g/kg). Compared with the control (10 m away from the core area), soil bulk density and soil total porosity decreased with the increased of trampling intensities in the buffer area, however, soil bulk density and soil total porosity had positive relation with elevated with trampling intensities in the core area.
