Public Greenbelt Layout Optimization for Ecological Civilization City Construction

Abstract:

For boosting public greenbelt (PG) construction level, hastening urban ecological civilization construction velocity, the optimization model and its algorithm for urban PG layout is studied. The layout optimization presupposition of urban PG is described. The bi-objective optimization model for urban PG layout is established. The optimization objectives consist of maximum consistency between PG distribution and population distribution, maximum PG area in certain region. In model constraints, budget capital investment sum for PG construction, distance tolerance threshold from each citizen’s habitation to nearest PG, sum of PG needed to be upgraded and reconstructed from grade two to grade one, minimum oxygen supply capacity from given greenbelt, maximum potential supply area of PG. Genetic algorithm (GA) is employed to solve above model, the main cycles of GA for above model are designed. Above greenbelt layout optimization model and its algorithm are validated.
