Optimum grass growing pattern of artificial grassland and sustainable utilization of water resources

A nonlinear multi-objective model was set up by coupling water requirement of grass, pumpages for irrigation and it responds to drawdown of groundwater table with response matrix approach. The optimum grass growing pattern and sustainable utilizing decision of groundwater system were obtained by solving nonlinear multi-objective model with multi-objective genetic algorithm which was used to evaluate the feasible solution how they match the objectives with expression matrix ordered by total fitness values.
