确保粮食安全和可持续资源管理已成为全球首要关切,促使人们高度重视土地适宜性分析,以提高农业生产。在这项研究中,采用AHP加权叠加法划分了桂林水稻种植适宜性,伊朗,水稻生产的中央枢纽。十六种气候,地形,和土壤变量进行了整合,并对各个地图进行了重新分类,以符合水稻生产的具体要求。结果显示了三个适合性类别:包括\'非常适合,\'\'合适,\'和\'适度合适\',占91%,6%,还有3%的土地,分别。土壤属性,特别是有机物,显著影响适用性(重量值为0.745),在评估中,地形和土壤因素超过了气候。虽然盐度通常不存在,有机质缺乏影响44%的土地。磷失衡很普遍,观察到10%的钾毒性。微量元素缺乏,尤其是铁和锌,被注意到。此外,结果表明,在评估研究区域内水稻种植土地适宜性方面,地形和土壤属性比气候相关因素起着更重要的作用。本研究对研究区域的所有变量进行了全面的空间分析,阐明水稻种植土地适宜性的复杂性。这些发现有助于理解粮食安全背景下的农业可持续性和资源管理战略。
Ensuring food security and sustainable resource management has become a paramount global concern, prompting significant attention to land suitability analysis for enhancing agricultural production. In this study, an AHP-weighted overlay method was employed to delineate
rice cultivation suitability in Guilan province, Iran, a central hub for
rice production. Sixteen climatic, topographic, and soil variables were integrated, and individual maps were reclassified to align with the specific requisites for
rice production. The results revealed three suitability classes: including \'very suitable,\' \'suitable,\' and \'moderately suitable\', covering 91%, 6%, and 3% of the land, respectively. Soil attributes, particularly organic matter, significantly influenced suitability (weight value of 0.745), with topographic and soil factors outweighing climate in assessment. While salinity is generally absent, organic matter deficiency affects 44% of the land. Phosphorus imbalances are prevalent, with potassium toxicity observed in 10%. Microelement deficiencies, especially in iron and zinc, are noted. Additionally, the results indicated that topographic and soil attributes played a more significant role than climate-related factors in assessing land suitability for
rice cultivation within the study area. This research provides a comprehensive spatial analysis of all variables in the study region, shedding light on the complexities of land suitability for
rice cultivation. These findings contribute to the understanding of agricultural sustainability and resource management strategies in the context of food security.
