The development course of Changyu Dongtian

　 Changyu cave sky, with its unique geological structure, large scale of cave group, unique mining method, unique cave sky scenery and unique cultural landscape, is a unique "cave sky culture" which integrates natural landscape, quarrying culture, religious culture, architectural art and ecological technology. Its internal meaning is to fully show the society of rational utilization of nature, harmonious coexistence of human and nature, and tenacious struggle The special "stone culture" of humanistic spirit. "Although it is made by people, it is like heaven", which is a stone legend with a history of more than 1500 years. Now, from this, we can deduce scenes of stone culture activities, let people feel the beauty of stone culture connotation, taste the charm of human harmony, and stone culture can continue to develop.
Protection of stone mines
　　In the old days, some cliff cliffs left behind by quarrying were beautified by Yao grass peach blossom and temples, and became the carrier of literature and art and religious activities. The development and utilization of Changyu Dongtian embodies the wisdom of the working people and the cultural essence of the integration of heaven and man in Chinese civilization. Inheriting this tradition, today, while focusing on the protection of the existing quarrying sites and their culture, people focus on the management and beautification of the environment of the Dongtian mine in Changyu, and develop its potential to a greater extent, so that it can be used for the benefit of the world.
For more than a thousand years of quarrying in Changyu, waste rock (soil) has removed the soil, vegetation, gravel and other covers covering the deposit, destroying the original homogeneous material layer of the site and breaking the complete ecological basement. In addition to quarrying, a large number of auxiliary facilities and buildings need to be built in quarrying activities, such as waste rock yard, waste dump, reservoir, transportation road, secondary processing plant, etc. the original homogeneous landscape has become fragmented, resulting in the enhancement of landscape heterogeneity. Now, on the premise that the transformation is based on the geological stability and no potential safety hazard, under the principle of "scientific planning, unified management, strict protection and sustainable utilization", we should pay attention to the protection of stone mines and adopt the regulation and development integrated with the landform. Use mountains instead of destroying them, combine mountain opening, mountain protection and mountain tour, conserve and restore the original plants, use local stones, create the landscape art with Changyu characteristics, create a good atmosphere for people and nature to get along harmoniously, and create a more reasonable and perfect development mode of scenic spots. For most of the caves, we should try our best to protect their original appearance, not to build randomly, or to design too many tourist facilities and carry out unsuitable tourism projects. In the scenic area, the old-fashioned, backward and disordered quarrying of rocks and minerals was stopped, and private quarrying of stones was banned. The reuse of waste rock will turn waste into treasure, which will be transported to mechanical gravel workshop for concrete raw materials. Demolition of a large number of ancient tombs, restoration of the unsightly wasteland, restoration of the site for waste rock accumulation, restoration of the hillside complex, and beautification of the landscape environment of Changyu. Protect and clean up the ruins, protect the ecological environment, and protect the stone cultural relics in the stone mines. Record the miner's trumpet, collect the stone folklore, sort out the data of quarrying technology, and protect the intangible cultural heritage of the stone mine.
Sustainable development in protection
　　Dongtian in Changyu is a natural and cultural landscape, which systematically and completely records the history of Quarrying and the inheritance of stone culture, thus forming a rock cave type scenic spot containing quarrying, stone using and stone appreciation, and rich in the essence of ancient and modern stone culture. Tourism development is an effective way for the sustainable development of stone culture. The publicity of stone culture tourist attractions has enhanced people's understanding of stone culture, expanded the influence scope of stone culture, and created a good atmosphere for the protection and development of stone culture. The intervention of tourism development realizes the interaction between economy and stone culture, strengthens the influence of human beings on stone culture, injects era factors into stone culture, and promotes the inheritance and development of stone culture.
From the very beginning, the tourism development of Changyu Dongtian has been firmly positioned in the stone culture, making the stone culture the main content and soul of tourism development.
