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。

Effects of Tourism Disturbance on Litter and Soil Hydrology Functions of Huangshui National Forest Park in Chongqing City

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.
