Leshan Giant Buddha, which has not fallen for thousands of years, closed his eyes and shed tears for four times. Is it a sign, or is it another reason?

As far as Sichuan is concerned, everyone's first impression must be the Leshan Giant Buddha in Sichuan, which was excavated in the Kaiyuan period of the Tang Dynasty (765,438+03) and carried out in the 19th year of Zhenyuan (803). It has existed for thousands of years. This is attributed to the proper drainage equipment of Jinding Giant Buddha, which plays a key role in maintaining Jinding Giant Buddha. There are horizontal drains on the 4th, 9th and18th floors in the bun on the top of Jinding Giant Buddha. Behind the ears, near the cliff, there are caves that are connected from top to bottom; There are holes on both sides of the sternum, but they are not drilled through each other. This kind of drainage ditch and cave form a drainage pipeline, moisture insulation and exhaust system for scientific research in the "body" of Jinding Giant Buddha, which prevents it from adhering to the weathered layer.

The neck and neckline of the Jinding Buddha also have gray folds. First, it has decorative design effect, and in addition, it can have drainage pipe effect. Ancient craftsmen set up some small and medium-sized sewage ditches for smooth drainage. Many people say that the giant Buddha in Leshan, Sichuan has a holy spirit, and once closed his eyes and shed tears when encountering disasters. It's the Jinding Buddha, caring about human sufferings. It is often said that it is because of ancient history that the Jinding Buddha cried four times before closing his eyes, namely 1962, 1963 and1976,2000. Because 1962 and 1963 happened to be in the flood disaster period of once every three years in China, 1976 was hit by the Tangshan earthquake, and in 2000, the Hejiang shipwreck occurred, causing 130 people to die. Therefore, many people say that the giant Buddha in Leshan, Sichuan once closed his eyes and shed tears when encountering disasters, but it is not.

How does Jinding Buddha close his eyes? The real reason why the Buddha closed his eyes and cried was the bad influence of acid rain caused by environmental pollution. In 1960s, with the development of the third-line construction, a large number of manufacturing enterprises and national defense security research institutions entered Leshan city one after another. 2/kloc-0 At the beginning of the 20th century, there were still paper industry and pharmaceutical enterprises discharging organic waste gas and sewage in the upstream and downstream of Qingyi River, which belongs to Leshan Giant Buddha in Sichuan, and there was also Wu Tong industrial production belt along chengdu-kunming railway in the northwest of Leshan City. Due to the extensive application of non-renewable resources, industrial capital construction and water conservancy construction, the environmental pollution in Leshan city has gradually intensified, causing the harm of acid rain, which is a complex organic chemical and physical change in the air. There are many kinds of strong oxidants and organic substances in the harm of acid rain, most of which are hydrochloric acid and sodium cyanide. In most cases, hydrochloric acid is the dominant factor, which will corrode Buddha statues.

In addition to the industrial park in Leshan City, the near sources of acid rain also come from economically developed industrial production belts such as Chengdu, Deyang and Mianyang, and areas such as Panzhihua and Chongqing in the west that are very easy to transmit environmental pollution to Jinding Giant Buddha. Moreover, Leshan City is located in Sichuan Basin, which is not conducive to the diffusion of air pollutants. In rainy and snowy weather, the air relative humidity is high, and the harm of acid rain to foundation settlement is more serious. In fact, it's not just Leshan. At the beginning of 2 1 century, acid rain covered most of 2 1 city and state in Sichuan Province, covering 80%. Under the erosion of acid rain, the architectural paint of Jinding Buddha's eye will fall off. From a distance, the giant Buddha in Leshan, Sichuan seems to have closed his eyes, and the mark washed away by precipitation looks like the giant Buddha in Jinding crying!

From 1960s to the beginning of 2 1 century, Leshan Giant Buddha in Sichuan has been eroded by acid rain. In 2007, the Jinding Giant Buddha was covered with Cang Sang, and the gray-black pattern on his face was like tears. His breast, abdominal cavity and feet were smashed into three pieces by weathering layer, revealing bright red "whole body muscles". The weathering layer of the nine-curved hanging plank road on both sides of Jinding Giant Buddha is serious, and the two doormen are also corroded and scratched all over. According to the radar detection nondestructive testing technology, the average thickness of slate in the right calf area of Jinding Giant Buddha is 2.7-3.35 meters, and the surface thickness of the abdominal cavity and chest area of Jinding Giant Buddha varies between 2.6-3.6 meters. There is a gap of 1 1 meter under the back of the right hand of Jinding Giant Buddha. The transformation can't solve the fundamental problem, so we must deal with the environmental pollution and surface water infiltration in Jinding Giant Buddha area.

Leshan city will intensify environmental improvement, and it is a historical moment for the giant Buddha to close its eyes. For more than ten years, the relevant departments have cleaned, repaired and decorated the head, shoulders, hands and feet of Leshan Giant Buddha in Sichuan. Weeds have been removed from the body of Leshan Giant Buddha in Sichuan, and the surrounding environment and landslides of Leshan Giant Buddha in Sichuan have been rectified. The natural environment around Leshan Giant Buddha in Sichuan has been greatly improved. At present, Leshan City has carried out environmental improvement in the whole province. The average annual concentration ratio of respirable particulate matter (PM2.5) in Leshan decreased by more than 19%, and the proportion of days with excellent natural ambient air index reached the average level of Chengdu Plain. The total amount of sulfur dioxide and nitrogen oxides decreased by 28% and 2 1% respectively compared with 20 15 years.

In the future, Leshan will effectively adjust the heavy chemical industry according to the industrial layout upgrade, vigorously promote the use and manufacture of alternative green energy, attach great importance to flue gas desulfurization and environmental protection of nitrogen oxides, and fundamentally reduce the harm of acid rain and environmental pollution. At present, more than 30 world cultural heritages in China are being endangered by environmental pollution. Emei Mountain, Taishan Mountain in Shandong, Huangshan Mountain in Fujian and Wuyishan Mountain in Fujian are all surrounded by acid rain and other harmful substances. Reducing environmental pollution is not only to protect ourselves, but also to protect China's world cultural heritage. Everyone should not only have the concept of green development, but also have green mountains and green waters.
