摘要

建立生态系统与农业机械化之间的联系有助于解决农业管理中的错误决策,防止对生态系统造成进一步损害。农业部门的管理者和决策者必须了解生态系统的动态和影响因素,以制定适当的可持续发展政策。本研究的重点是在考虑技术和能源参数的情况下,确定伊拉姆省农业实践中决定作物模式和投入分配的最佳条件。在该地区种植一公顷小麦和大麦平均需要消耗各种能源 1.79 千兆焦耳,而这些作物的能源产出估计为 38.04 千兆焦耳/公顷。这项研究涉及伊拉姆省南部地区种植小麦、大麦、饲料玉米和油菜籽的农民,包括阿布旦、达雷沙尔和德赫罗兰等城市。研究建议调整种植模式,包括在最佳条件下减少小麦种植,增加灌溉饲料玉米种植。研究还建议探索雨养种植或提高雨养小麦的产量,以抵消小麦种植的减少。目标规划模型表明,种植模式将向可持续性转变,重点是小麦、大麦、饲料玉米和油菜籽作物,包括扩大灌溉小麦、大麦和饲料玉米的种植面积。努力的目标是提高灌溉作物的生产率,以促进该省的可持续性,并改进农业生产方式,以实现长期可持续性目标。

Optimizing cropping patterns and resource allocation for sustainable agricultural development: A case study of Ilam province, Iran

Establishing connections between ecosystems and agricultural mechanization can help address erroneous decision-making in agricultural management and prevent further harm to ecosystems. It is essential for authorities and decision-makers in the agricultural sector to understand ecosystem dynamics and influencing factors to develop appropriate policies for sustainable development. This study focuses on identifying optimal conditions for determining crop patterns and input allocation in Ilam province's agricultural practices, considering technical and energy parameters. Cultivating one hectare of wheat and barley in the region requires an average energy consumption of 1.79 GJ from various sources, with an estimated energy output of 38.04 GJ ha−1 for these crops. The research involved farmers cultivating wheat, barley, fodder maize, and canola in the southern region of Ilam province, covering cities like Abdanan, Dareshahr, and Dehloran. The study suggests adjustments to cropping patterns, including reducing wheat cultivation and increasing irrigated fodder maize cultivation under optimal conditions. It also recommends exploring rainfed cultivation or enhancing the yield of rainfed wheat to offset the reduced wheat cultivation. The goal planning model indicates a shift towards sustainability, with changes in cropping patterns focusing on wheat, barley, fodder maize, and canola crops, including expanding the cultivation areas of irrigated wheat, barley, and fodder maize. Efforts aim to enhance the productivity of irrigated crops to promote sustainability and improve agricultural practices in the province for long-term sustainability goals.
