This study investigated the distribution and types of surface weathering diseases on rock art in the Helankou area, using field surveys and statistical analyses. In addition, a damage index analysis method was proposed to quantify the effect of weathering diseases on the integrity and preservation status of the artefacts. The study findings revealed that the weathering diseases affecting the rock art in Helankou primarily encompass surface delamination, splitting, and blistering. Significant variations were observed in the extent of damage to the rock art depending on the rock surface type. Spheroidal surfaces and vertical planes typically exhibit more pronounced damage, whereas parallel planes experience a relatively lower impact. A comparative analysis of the damage indices revealed that the most significant disease affecting the integrity and preservation status of the rock art is delamination, which is predominantly observed on the surfaces of spheroidal weathering planes. This study will facilitate the development of protective measures for paintings. This will lead to improved management strategies and the implementation of measures tailored to different levels of weathering severity.
