According to the person in charge of Guihai Forest of Steles Museum, there are many seriously damaged steles in Longyin Rock and Longyin Cave, where cliff stone carvings are very concentrated, which are affected by the seepage of limestone pores and cracks, the development of calcium carbonate and stalactites. , causing the surface of the stone carving to be covered, with small pieces and flakes falling off locally, and the handwriting on the tablet surface becoming shallow; Soluble carbonate rocks will not only cause dissolution under the action of water seepage, but also precipitate and cover calcium deposits on the surface of stone carvings, which will affect the artistic value of stone carvings. The huge dangerous rocks formed by the development of some rock cracks will cause the safety hidden danger of stone carving carriers and seriously threaten the preservation of stone carving. In addition, Longyin Cave and Longyin Cave are close to the Jiang Xiaodong River, and most of the inscriptions in the cave will be submerged by the rising water level in flood season every year. The erosion of the river will cause serious damage to the stone carvings, and deposit a lot of sediment, defacing the tablet surface and inscriptions, and some low inscriptions will even be completely submerged in mud; After the water level drops, stone carvings are easily exposed to the sun and influenced by the change of dry humidity, which accelerates the weathering of stone carvings. In addition, tourists often touch the surface of stone carvings or carve with knives and sharp tools, which also artificially destroys the surface of stone carvings. Under the combined action of various natural and human factors, stone carving will become "sick".
The site map of Jingjiang Mansion in the south of the parrot hill in the north of our city is a cliff stone carving in the Song Dynasty, with a height of 3.4 meters and a width of 3 meters. It is one of the two oldest existing maps of ancient stone carvings in China and the largest one in the world. This map uses landscape symbols for the first time, which reflects the scientific and solid nature of Guilin's urban construction at that time and is a great pioneering work in the history of map design in China. This map records the city, government offices, barracks, neighborhoods, mountains and rivers, places of interest of Jingjiang Prefecture (now Guilin) in detail, and is an important material for studying the military defense of Jingjiang Prefecture in the late Southern Song Dynasty and the history of ancient cartography in China.

The map of Jingjiang Mansion and the attached map of Jingjiang Mansion are damaged by two thirds. In addition, during the investigation, the reporter also found that there were very serious scratches on the pavilion, and there were some ashes of incense and paper money in the pavilion. It seems that someone really worships this stone carving as a statue. Many plants around the exhibition hall have dried up because of the cold weather. If there is a fire, it may cause more serious damage to this priceless stone carving. There is a crumbling broken tree around the pavilion. Once it collapses, it may break the monument pavilion. ...
