In the grand map of ecological and environmental protection, the sand and gravel industry occupies a unique and critical position. As a basic building material, sand and gravel are widely used in various construction projects, and its production, transportation and other links are closely connected with the ecological environment. In the process of promoting the construction of a beautiful China, the central ecological and environmental protection inspectors attach great importance to the possible ecological damage and environmental pollution problems in the sand and gravel industry. The inspector's sword hangs high, not only to escort the high-quality economic and social development, but also to conduct all-round review and supervision of the sand and gravel industry, coordinate various key relationships, and strive to protect the bottom line of the ecological environment while ensuring the reasonable development needs of the sand and gravel industry. Recently, Sun Jinlong, Secretary of the Party Leadership Group of the Ministry of Ecology and Environment, and Huang Runqiu, Minister of the Ministry of Ecology and Environment, published a signed article "Guarding the Construction of a Beautiful China with the Sword of Inspectors" in Qiushi magazine.
