With improving the quality of the ecological environment as the core, and focusing on the concept of "accurate measurement, precise calculation, effective management, and good governance," based on the ecological environment big data resource center, an integrated and comprehensive ecological environment service business system is established around the "source-network-site-factory-river-sea" to create a smart monitoring platform, smart regulation platform, smart decision-making platform, and smart service platform. This will form a "system management-water treatment" new model of intelligent environmental management and targeted engineering governance that promotes each other positively. The ultimate goal is to achieve "three-dimensional monitoring, precise regulation, scientific decision-making, and convenient service" of ecological environment management.
