In this paper, the light pollution problem is studied. Firstly, the principal component analysis method is used to delete and merge the existing data, so as to get the final judgment index. Secondly, the entropy weight method and TOPSIS evaluation method were combined to obtain the light pollution risk index (LDI) with comprehensive scores, and the K-Means clustering method was adopted to classify figure the light pollution risk levels according to LDI. Finally, indicators were collected and ranked for four regions: protected area, rural community, suburban community and urban community, so as to determine their risk levels. The study found that the levels of light pollution risk in protected areas, rural communities, suburban communities and urban communities gradually increased.
