Dynamic Simulation of Construction System of Rural Eco-Residential Areas Based on Couplings

Construction system of rural eco-residential areas was constituted with construction subsystem as the main ponderance, couplings influence exist between subsystems, built a couplings model for construction system of rural eco-residential areas based on grayer relatedness degree, take Yanhe village as an example, simulated and calculated the couplings degree of construction system of Yanhe village eco-residential areas at different times by simulated three situation of construction model of construction system of Yanhe village eco-residential areas, including sustainable development, stand development and reverse development, drew conclusions with sustainable development has a high degree of system couplings.
