Therefore, coordinating the development of basin and region, region and industry, and human, city, land, industry and green is an important way to achieve the goal of sustainable development of social economy and ecology.

At present, the related researches are mostly based on the principle of "four water four fixed" to construct a multi-objective regulation model to regulate water resources at the administrative district or city cluster scale, ignoring the coordination of the water, energy, food and ecological pattern of the basin and the regional social economic development, the competition of resources among regions and industries, and the multi-element coordination of human, city, land, industry and green. It is difficult to give a set of feasible water resource allocation schemes for the size of human, city, land, industry and green and the main industries. SUMMARY
