摘要

[目的] 探索不同旅游干扰强度对景区枯落物及土壤蓄水能力的影响，为景区管理措施制定和生态环境改善提供一定的参考。[方法] 以重庆市黄水国家森林公园为研究对象，分析非干扰、轻度干扰、中度干扰和重度干扰4个处理条件下景区枯落物及土壤蓄水能力的变化。[结果] 随着旅游干扰强度的增强，景区枯落物及土壤蓄水能力均显著降低，而土壤容重则显著提升（p<0.05）。与未干扰相比，重度干扰下景区枯落物总蓄积量、未分解层和半分解层蓄积量分别显著降低55.30%，57.47%和49.19%（p<0.05）；未分解层枯落物最大持水率、最大拦蓄率、有效拦蓄率、最大持水量、最大拦蓄量及有效拦蓄量分别降低19.83%，24.83%，20.22%及57.89%，56.67%%和62.35%，而半分解层则分别降低30.01%，33.21%，37.48%及69.90%，70.94%，72.77%；土壤容重提升97.33%（p<0.05），总孔隙度、毛管孔隙度、非毛管孔隙度、最大持水量、毛管持水量、非毛管持水量、初渗率、稳渗率、平均渗透率和渗透总量分别提升26.57%，8.83%，17.74%，38.64%，42.98%，32.13%，67.01%，65.23%，64.22%和44.01%（p<0.05）。[结论] 旅游干扰通过降低景区枯落物尤其是半分解层枯落物和土壤蓄水能力而影响景区生态系统水文调节功能。

Abstract

[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.
