摘要
Cropping structure has a close relationship with the optimal allocation of agricultural water resources. Based on the analysis of the relationship between agricultural water resources and sustainable development, this paper presents a multi objective fuzzy optimization model for cropping structure and water allocation, which overcomes the shortcoming of current models that only considered the economic objective,and ignored the social and environmental objectives. During the process, a new method named fuzzy deciding weight is developed to decide the objective weight. A case study shows that the model is reliable, the method is simple and objective, and the results are reasonable. This model is useful for agricultural management and sustainable development.
由于作物种植结构与农业水资源优化配置关系密切,因此本文在论述我国农业水资源现状与农业可持续发展关系的前提下,提出作物种植结构与水量优化分配的多目标模糊模型,克服了以往方法中只考虑经济效益目标,而忽视社会效益和生态效益目标的不足。为更好的解决权重问题,本文提出模糊定权的方法来确定指标权重。应用实例表明,理论模型严谨,物理意义明晰,计算方法简洁,为区域农业可持续发展规划提供了较完善的多目标模糊优化理论、模型与方法。
