Many years ago, illegal sand mining in northern Jiangsu was repeatedly banned, seriously damaging the ecosystem of rivers and lakes. Take Luoma Lake, which spans the cities of Xuzhou and Suqian, as an exampleBefore the complete ban on mining, there were nearly 1,000 sand mining pump ships in the lake area, with an annual mining volume of nearly 100 million tonsThere are more than 10,000 people directly involved in sand management. A large number of sand mining vessels have been digging and mining indiscriminately, resulting in the continuous deterioration of the lake water, the desertification of the lake bottom in the sand mining area, the collapse of the embankment, and the disappearance of many islands, which have serious adverse effects on flood control, water supply, shipping and the ecological environment.
In order to fight the battle of pollution prevention and control in depth, and curb illegal sand miningThe cities (counties) in northern Jiangsu and the Huai Commission Yishu Si Water Conservancy Management Bureau jointly issued the "Notice on Prohibiting Illegal Sand Mining in the Waters of Luoma Lake".Sand mining is completely prohibited in the waters of Lake Luoma. Through heavy blows and ruthless attacks, 110 criminal suspects were arrested, and 13 people suspected of job-related crimes were investigated and punished. From cracking down on illegal sand mining to a complete ban on mining, from centralized docking to the comprehensive dismantling of illegal sand mining pump ships, Luoma Lake has gradually regained the gratifying scene of rippling blue waves, clear water, fish fat, and migratory birds.
However, after the ban on mining of lake sandThe huge sand gap triggered a series of chain reactions, and the market plummeted and led to a sharp rise, and the yellow sand of the previous 100 yuan a car actually rose to two corners per catty. Driven by greater profits, illegal mining has been transferred from rivers and lakes to the ground, and illegal sand mining and processing have begun to encroach on cultivated land resources, especially in the border area between Sulu and Luzhou provinces, where there are a large number of "flower arrangement".
The problem of "small scattered" land destruction and illegal mining and illegal land occupation and sand washing is intertwined, resulting in many agricultural lands being scarred, and the sand control and mining ban has appeared "pressing the gourd to float the scoop". In the face of rigid demand, we must avoid taking care of one or the other, and the combination of dredging and blocking can cure both the symptoms and the root causes. **Illegal sand mining, on the one hand, to resolutely block the "side door", in the handling of provincial cross-border and other complex issues to strengthen law enforcement joint cooperation, to avoid fighting alone, information exchange between the two places to be timely and sufficient, the establishment of a long-term linkage law enforcement mechanism, so that the illegal mining gang has no chance.
On the other hand, it is also necessary to scientifically open up the "front door".The sand mining management agency is established by the local government, and the "five unified" management mode of unified organization and leadership, unified mining and operation, unified fee collection, unified comprehensive law enforcement, and unified benefit distribution is established. Realize the transformation from disorderly illegal mining to orderly and scientific mining, promote the benign and healthy development of the sand and gravel market, avoid vicious competition and disorderly over-mining, and alleviate the contradiction between supply and demand of construction sand.
At the same time, it is necessary to increase the promotion of recycled sand and gravel from construction waste. In recent years, with the demolition and reconstruction, the renewal of cement roads, construction waste everywhere has become a "big problem" for pollution prevention and control, if it is just a simple landfill treatment, not only a waste of resources, but also damage the ecological environment. We should adhere to policy guidance, recycle the recycling of construction waste and gravel, and save the mining and use of natural sand and gravelReduce environmental damage and landfill landfilling, avoid secondary environmental pollution, protect cultivated land, truly realize the recycling of resources, and effectively ensure the results of ecological environment and air pollution prevention and control.
