Abstract

Surface water is one of the important landscape resources in tourist attractions. Due to tourism activities, the surface water quality (SWQ) in scenic was often damaged. An example of the Lushan Scenic, the SWQ, was analyzed and evaluated by water sampling and laboratory analysis methods. The results explained that the SWQ of Lushan Scenic was seriously damaged. The comprehensive index explained that the SWQ of seven sampling dots was from mild pollution to extreme pollution. The main pollutants were ammonia nitrogen, total nitrogen, and total phosphorus, and the TN and TP were the most serious. According to the data of tourists in 2017, the emergency water capacity stored by reservoirs was 32.5days if there was no raining in Lushan Scenic. The main factors affecting the SWQ were tourism activities, such as tourists, hotels, restaurants, and other commercial activities, and pollutants discharged from domestic water were not completely treated in Lushan Scenic.
