Recently, tourists discovered that the Tianchi Scenic Area in Chongqing Wuling Mountain Forest Park has installed stainless steel on the entire bottom of the pool. After the incident spread online, it attracted the attention of netizens. Why was Tianchi directly transformed into a 'stainless steel basin'? 'This is the legendary' tiling the Great Wall '... related topics have been trending continuously. On May 29th, the person in charge of the scenic area explained that the original natural water pool continued to leak due to karst topography. The scenic area began implementing anti-seepage projects in 2014, initially using conventional measures such as bottom hardening and paving. However, due to deformation of the karst geological structure and water pressure, the leakage problem still could not be solved. After two or three years of continuous demonstration, the stainless steel installation project solved the problem of leakage after completion in 2017. The total cost of the project is over 20 million yuan, of which the cost of stainless steel materials is about 10 million yuan, fully borne by the operator of the scenic spot - Taiji Group. At this point, the scenic area has provided a relatively comprehensive explanation. Ecological environment protection and transformation should obey science, but "obeying science" should not be narrowly understood as experts' closed door research and decision-making. We should also consider the harmonious relationship between humans and nature, and listen to the thoughts of ordinary people: do we want to see such beautiful natural lakes turn into stainless steel bottoms? Even from a utilitarian perspective, as a 4A scenic spot, can tourists accept this kind of "cosmetic" attraction? Firstly, the ecological concept of "green mountains and clear waters are as valuable as mountains of gold and silver" has deeply penetrated people's hearts, and building a beautiful China is also the conscious responsibility and mission of every citizen. Ordinary netizens may not be able to articulate profound theories of ecological protection, but a beautiful natural mountain lake with stainless steel at the bottom has become a de facto "stainless steel basin", almost permanently changing the ecological appearance and environment of the natural lake. Therefore, the public still has many questions: is it necessary to do so? Is laying a stainless steel bottom the only solution? How to deal with unexpected serious side effects in the later stage? The natural flow and circulation of water, including the sand, gravel, and aquatic plants at the bottom of the pool, together form the ecosystem in the pool. Now that stainless steel has been replaced, how can the original water ecological environment be maintained? Secondly, Wuling Mountain Forest Park is extremely dangerous, spectacular, and beautiful. The water-soluble rocks derived from karst landforms also determine that this type of landform is bound together with the characteristic of "water seepage". In order to ensure that Tianchi Lake maintains its stability and prevents water seepage, and is conducive to receiving tourists and serving tourism, the bottom is fully covered with stainless steel, completely changing the original karst landform. Is this kind of protection completely opposite to the original intention of ecological protection? Again, what is the purpose of this investment? According to the disclosure, the total cost of the entire project is over 20 million yuan, all of which is borne by the operator of the scenic spot, and no direct financial funds have been used. However, it should be considered that Taiji Group itself is a large state-owned enterprise. As a large pharmaceutical company, its investment in Wuling Mountain Forest Park is also an important part of the layout of the "big health" and wellness industry. During the construction of Wuling Mountain Forest Park, Taiji Group was fined by the local authorities for illegally occupying 0.4685 hectares of forest land. Based on this, is there a factor of haste and instant benefit in laying stainless steel bottoms for Tianchi's economic and ecological accounts? Whether the technical solution is necessary, whether the ecological cost is controllable, whether there are milder alternative solutions, and so on, all require more authoritative answers. In fact, the whole Wuling Mountain, spanning four provinces and cities of Hunan, Hubei, Chongqing and Guangxi, is where Tao Yuanming's "Xanadu" is located. It is deeply rooted in the cultural memory of Chinese people, not an artificial "scientific and technological space". And laying stainless steel at the bottom of Tianchi in karst terrain is indeed beyond many people's imagination and has also changed the natural landscape. For these unprofessional questions raised by the public, we hope that local functional departments can provide responses instead of the companies themselves explaining. High mountain lakes belong to the national assets and must be left to future generations. (New Society)
