The rationality of the location of public toilets in scenic spots directly affects the
satisfaction of tourists, especially in scenic spots with complex terrain, the uneven distribution of toilets
increases the inconvenience of tourists to go to the toilet and affect their tour experience. To solve this
problem, this paper takes Seven Stars - Scenic Spot in Guilin as an example, applies the maximum
coverage model to optimize the location of public toilets, collects the spatial information of the scenic
spot and constructs a vector map for analysis. The study found that the coverage rate of the existing
toilets in Seven Stars - Scenic Spot (the proportion of the number of scenic spots covered by toilets in
the total number of scenic spots in the region) was 58.8% , and there was room for optimization. After
optimizing the layout, with the same number of toilets, the maximum coverage model was applied to
increase the coverage rate of scenic spots to 84.3% , which verified the effectiveness of the model in
layout optimization. Further, with the addition of one and two toilets, the coverage rate has increased to
88.2% and 92.1% , respectively. The maximum coverage model is feasible in the optimization of toilet
location in scenic spots with complex terrain, and provides a scientific basis for the optimization of toilet
layout in Seven Stars-Scenic Spot. At the same time, it has certain reference value for other scenic
spots of the same type, and helps to improve tourist experience.
