A Study on the Scenic Beauty of Huangguoshu Scenic Area Based on SD and SBE Method

To promote the protection and development of tourism resources in waterfall-type scenic spots, scenic beauty estimation procedures (SBE) and semantic difference (SD) methods were used to study the scenic beauty of Huangguoshu. The results showed that the landscape beauty of the Huangguoshu Scenic Area was relatively good, and the overall beauty of Huangguoshu Waterfall was the highest. Among different scenic spots, the SBE value of the Huangguoshu Waterfall Scenic Area had the maximum value, and it was significantly different from that of the Tianxing Bridge Scenic Area and Doupotang Scenic Area. The SBE value of different landscape types, from high to low, was water system, overall landscape, mountain, vegetation, bridge, and building, and the beauty of the natural landscape was higher than that of the artificial landscape. The landscape of waterfalls showed a decreasing trend from large to small. The main factors affecting the beauty of the Huangguoshu Scenic Area were landscape identifiability, landscape coordination, naturalness of mountains, surrounding plant communities, majesty and beauty of water systems, relationship between mountains and rivers, and plant space enclosure. The scenic spots in the Huangguoshu Scenic Area that were lower than the lower limit of the scenic beauty threshold (13.73) were all artificial landscapes. The Huangguoshu Scenic Area was characterised by the beauty of harmonious symbiosis of green ecology, majestic beauty, and natural beauty of karst geology. Beauty threshold monitoring can provide technical support for the dynamic protection and optimisation of the scenic area. The results of this study provide a theoretical basis for the dynamic management and regulation of scenic spots and are of great significance for maintaining the aesthetic value of scenic spots and planning and building scenic spots with regional characteristics.
