旅游活动对水土流失的影响

水土流失是一个全球性环境问题,引发和影响水土流失的因素是多方面的.人类活动更加剧了水土流失的严重程度.随着旅游业的发展,旅游活动对水土流失的影响日趋严重.首先分析了各种旅游活动及相关服务设施对水土流失的不利影响,探讨了旅游活动强度及其对水土流失影响程度的相互关系,建立了旅游活动对水土流失的影响模型,并据此提出了旅游风景区水土流失防治与管理对策.

Recreational Impacts onErosion and Runoff

Soil erosion, as a global problem, can be caused and impacted by many factors. Human activities aggravated the soil erosion, and a number of impacts of recreation on soil erosion were appearing with the development of tourism. The authors summarize the recreational activities and recreation infrastructure that negatively impact on soil erosion, and discuss that heavily used recreational sites have significantly higher impacts on erosion than moderate and light-use areas, and give the impact modeling of recreation on erosion. The management policies of soil and water conservation are provided for recreation sites.
