The second is to increase investment in scientific research in the field of soil restoration, and the introduction of new technology, to encourage independent innovation. The third is to fix soil combined with related industrial projects and avoid redundant construction. The last one is to intensify propaganda to improve public consciousness of the soil pollution prevention and control.
