摘　　要：水土流失影响山地旅游景观质量,成为当前山地旅游地普遍性的环境问题之一。通过土壤与水体浊度模拟实验表明,水土流失以改变水体浊度从而影响景观观光质量,20NTU浊度可作为次降雨水土流失对水体景观影响的临界值。以浙江省天台县石梁景区实证研究得到,不同流域降雨侵蚀对水体浊度影响具有差异性,同一流域次降雨侵蚀对观光水体浊度影响受流域降水强度与降水量共同作用。At present, soil erosion has become one of the universal environment problems in mountain tourism destination. The important reason of the decrease of ornamental water landscape quality in mountain tourism region during the rainfall stage is the influence of the water and soil loss on water turbidity. The empirical study in Shiliang scenic spot in Tiantai county, Zhejiang Province shows that the influence extent of rainfall erosion on watershed ornamental water is affected by both precipitation intensity and rainfall quantity. The water turbidity value in watershed decreases rapidly after the rain stopped. The influence of rainfall on water turbidity in different watershed is based on vegetation, land utilization and other characteristics. Therefore, reduce the quantity of soil erosion is the important approach to improve the quality of landscape in mountain tourism destination.
