Evaluation of water erosion loss on the northern slope of Tianshan Mountains under tourism disturbance: Taking west Baiyanggou watershed mountain scenic spot as an example

为探讨旅游干扰下山地景区水蚀强度和经济损失变化规律，以水蚀典型区——西白杨沟流域山地景区为案例地，基于样地调查数据，采用中国土壤流失方程（Chinese soil loss equation，CSLE）与水蚀经济损失评估模型，定量估算不同旅游干扰强度下水蚀经济损失，分析西白杨沟景区水蚀经济损失变化规律及其与土壤理化性质、植被覆盖度的关系。结果表明：不同旅游干扰强度下土壤理化性质、植被覆盖度差异显著。与对照组相比，重度干扰区土壤含水量、饱和含水量及土壤孔隙度的降幅分别为51.67%、32.23%、13.30%；土壤碱解氮、有效磷及有机质含量均随干扰强度增加呈下降趋势，而速效钾含量却趋于增加；与对...

Summary:为探讨旅游干扰下山地景区水蚀强度和经济损失变化规律，以水蚀典型区——西白杨沟流域山地景区为案例地，基于样地调查数据，采用中国土壤流失方程（Chinese soil loss equation，CSLE）与水蚀经济损失评估模型，定量估算不同旅游干扰强度下水蚀经济损失，分析西白杨沟景区水蚀经济损失变化规律及其与土壤理化性质、植被覆盖度的关系。结果表明：不同旅游干扰强度下土壤理化性质、植被覆盖度差异显著。与对照组相比，重度干扰区土壤含水量、饱和含水量及土壤孔隙度的降幅分别为51.67%、32.23%、13.30%；土壤碱解氮、有效磷及有机质含量均随干扰强度增加呈下降趋势，而速效钾含量却趋于增加；与对照组相比，轻度、中度、重度干扰区植被覆盖度分别下降14.18%、43.32%、92.35%。随旅游干扰强度的增加，土壤可蚀性K值与生物措施B值明显增加，土壤侵蚀量呈显著增长趋势（P
