Effects of Tourism Disturbance on Litter and Soil Hydrology Functions of Huangshui National Forest Park in Chongqing City
[Objective] The effects of different tourism disturbance intensity on litter and soil water-holding capacity in the scenic area were explored in order to provide some reference for scenic area management measures and ecological environment improvement.[Methods] The Huangshui National Forest Park was selected as experimental object and the changes of litter and soil water-holding capacity were analyzed under four treatments:undisturbed area
light disturbed area
moderate disturbed area and severe disturbed area.[Results] With the increase of tourism disturbance intensity
the litter and soil water-holding capacity were decreased significantly
while the soil bulk density was increased significantly (p<0.05). Compared with undisturbed area
the total accumulation of litter
decomposed litter and semi-decomposed litter were decreased by 55.30%
57.47% and 49.19% respectively (p<0.05); the maximum water-holding rate
maximum interception rate
effective interception rate
the maximum water-holding capacity
maximum interception capacity and effective interception capacity of undifferentiated litter were decreased significantly by 19.83%
24.83%
20.22%
57.89%
56.67% and 62.35%
respectively
but the semi-decomposed litter were significantly decreased by 30.01%
33.21%
37.48%
69.90%
70.94% and 72.77%
respectively. The soil bulk density of scenic spot under serve disturbance intensity was significantly increased by 97.33%
while the soil porosity
soil capillary porosity
soil non-capillary porosity
soil maximum water-holding capacity
soil capillary water capacity
soil non-capillary water capacity
soil initial infiltration rate
soil stable infiltration rate
soil average infiltration rate and soil total infiltration were significantly decreased by 26.57%
8.83%
17.74%
38.64%
42.98%
32.13%
67.01%
65.23%
64.22% and 44.01% (p<0.05)
respectively.[Conclusion] Tourism disturbance decreased the hydrological regulation function of the scenic area ecosystem by reducing the litter
especially the semi-decomposed litter and the soil water-holding capacity.
