摘要:

优化出石羊河流域主导作物适种优劣顺序,为流域综合治理和农业种植结构调整提供借鉴。以流域种植作物为研究对象,以作物经济、社会、生态的综合效益最大化为目标,建立基于综合效益的主导作物优化顺序模型,优化提出石羊河流域主导作物种植顺序。结果表明:石羊河流域作物综合效益优先种植顺序为:洋葱、籽瓜、小麦、玉米、辣椒、棉花、茴香、向日葵。石羊河流域种植结构调整和主导作物推广中,应按照作物经济、社会和生态综合效益最大的原则,根据石羊河流域主导作物综合效益优化顺序结果进行推广应用,为石羊河流域节水高效优质农业发展奠定基础。

Abstract:

The study aims to optimize the planting sequence of leading crops in Shiyang River Basin, and provide reference for watershed management and the adjustment of planting structure. Taking the leading crops as subjects, we maximized the comprehensive benefits of crop economy, society and ecology, established the optimized sequence model of leading crops based on the comprehensive benefits, and proposed the planting sequence of leading crops in Shiyang River Basin. The results show that the optimized planting sequence of leading crops is onion, seed melon, wheat, corn, pepper, cotton, fennel and sunflower in the Shiyang River Basin. In the process of the planting structure adjustment and leading crop extension in Shiyang River Basin, the principle of maximizing the comprehensive benefits of crop economy, society and ecology should be followed, and the results of the optimized planting sequence of leading crops should be applied, in order to lay a foundation for the development of water-saving, efficient and high-quality agriculture in Shiyang River Basin.

Key words: comprehensive benefits, leading crops, planting structure, optimized sequence, ShiYang River Basin
