The invention discloses a four-water four-fixation regulation and control method and
system based on human-city-land-production-green-water interaction, and the method comprises the steps: 1, determining a regulation and
control unit based on a
watershed water-energy-grain-ecological pattern and a regional social and economic development
layout; 2, constructing a target function based on
drainage basin, urban agglomeration and administrative region function positioning; 3, constraint condition construction is completed based on the available
water volume, the
water demand, the development scale, the
food safety production volume and variable nonnegativity; 4, completing the construction of a'four-water four-definite 'multilayer multi-target regulation and control model according to the target function and the constraint condition; and 5, solving the model to obtain the
population, city, land, industry and ecological scales of the regulation and
control unit and the water distribution amount of the water users. According to the method,
drainage basin water-energy-grain-ecological pattern and regional social, economic and
ecological development are planned as a whole, water-social, economic and ecological coordinated development is achieved, intensive benefits are exerted, and collaborative development of water, people, city, land, production and green is promoted.
