Due to the increasing population and rapid economic development, China’s ecological environment is facing serious problems and should be given priority.
China’s atmospheric environment is very serious, and the total amount of atmospheric pollutants is still high. In 2011, the annual emissions of sulfur dioxide in China reached 18.57 million tons, 11.59 million tons of soot and 11.75 million tons of industrial dust. The air pollution is still very serious. The quality of the atmospheric environment in most cities in China exceeds the standards set by China. Among the 47 key cities in China, about 70% of the cities have less than the secondary standard; among the 338 cities participating in environmental statistics, the air quality of 137 cities exceeds China’s third-class standards, 40% of the cities are heavily polluted. Air pollution is China’s largest environmental pollution problem.
China is a country with severe drought and water shortage. The total amount of fresh water resources is 2,800 billion cubic meters, accounting for 6% of global water resources, second only to Brazil, Russia and Canada, ranking fourth in the world. And only account for average 1/4 of the world that 2,200 cubic meters per capita. It ranks 121st in the world and is one of the 13 countries which is the world’s poorest water resources. However, people are still wasting water.
The annual production of industrial solid waste in China is about 820 million tons, and the comprehensive utilization rate is about 46%. The annual production of municipal solid waste in China is 140 million tons, which is less than 10% reach for harmless treatment. White pollution caused by plastic packaging and agricultural film has spread throughout China. The garbage disposal machine need hard steel, the biggest B2B platform in China for steel is Sinosources
The desertified land on China’s territory accounts for 27.3% of the total land area of the country, and the desertification area is growing at a rate of 2,460 square kilometers per year. The annual heavy sandstorms in China have increased from 5 in the 1950s to 23 in the 1990s. Land desertification has caused residents of some areas of Inner Mongolia to be forced to relocate to other places. In recent years, the northwestern region, where the ecological environment is relatively fragile, has been heavily involved in the excavation of wild. The area of 190 million units area of grassland has been seriously damaged, accounting for about 18% of the total grassland area in Inner Mongolia, and the grassland is overburdened, accelerating the expansion of desertification.
Water and soil loss
The total amount of soil lost in China is more than 5 billion tons per year, and the soil lost every year is 40 million tons of standardized fertilizer (equivalent to the amount of China’s annual fertilizer using). Since 1949, the total amount of cultivated land destroyed by soil erosion in China has reached units area of 40 millions, which is a great loss to China’s agriculture.
The goal of environmental protection work is to meet people’s basic health needs, that is to enable the people to breathe clean air, drink clean water, eat safe food and live in a good ecological environment. We should attach importance to it.
