Solving The Multi-Objective Optimization Model for Alpine Grassland Grazing With Modified Genetic Algorithms

Three-Rivers District is an open complex ecosystem with alpine grassland characteristics, animal husbandry is the leading industry and the pillar of herders' production and life. In this paper, we established an optimization yak structure model for grazing yak in alpine grassland in Three-Rivers Source area, the solution process was simulated by genetic algorithm, and quantitatively analyzed the relationship between grassland ecosystem and livestock husbandry, finally obtained the optimum slaughtered structure of yak population.
