Soil erosion caused by rainfall can affect water quality of the tourism river. This paper explores the regularity of effect of soil erosion on sightseeing water, which has certain practical significance of high quality display of tourism landscape resources. A survey is done on how rainfall affects water landscape quality in Shiliang scenic spot in Tiantai County of Zhejiang Province of East China. Through the field investigation, rainfall and tourism water turbidity data are obtained, and the relationship between rainfall and river water turbidity is established. After exploring the critical value of rainfall impact on tourism, rainfall characteristics, temporal difference and regularity of color changes, this paper points out that the threshold definition of characteristics of rainfall impact on tourism is related to the landforms, vegetation, soil and other relevant properties in the basin. Results show that the critical rainfall intensity of rainfall impact on tourism is 10 mm/ h, and the critical precipitation is 15 mm in Shiliang scenic spot. This paper proposes the concept of rainfall impact on tourism in the water landscape, and provides the reference method of determining the threshold of rainfall impact on tourism.
