Population growth has led to excessive land use, affecting soil suitability and sustainability. Detailed soil characterization and land evaluation for various land uses are essential steps toward achieving food security and sustaining the environment. This study classifies soils and assesses their suitability for tomato cultivation using the FAO Land Assessment Framework and Analytical Hierarchy Process (AHP) model. The land use requirements were matched with land suitability criteria, and the Analytical Hierarchy Process (AHP) was used to determine the relative importance of each evaluation criterion. Soil morphological and physicochemical properties were analyzed across different land uses. Based on USDA Soil Taxonomy, the soils under land use HK1 were identified as Typic Endoaqualfs, HK2 as Typic Albaqualfs and Inceptic Haplustalfs, while HK3 was categorized as Typic Haplustalfs and Typic Plinthaqualfs. The World Reference Base classification system identified these soils as Gleysols for soil unit HK1, Luvisols for pedon HK2P1, and Lixisols for the remaining soil units. This study demonstrates the effectiveness of the AHP method in logically determining the weights of multiple parameters in a multi-criterion approach. The results show that 89.73 % of the area is highly suitable for tomato cultivation, while 10.27 % is moderately suitable. The primary limitations of these soils are low fertility and poor drainage. The study suggests that management techniques including incorporation of organic matter, inorganic fertilizers and improved drainage conditions are needed for sustainable productivity.
人口增长导致土地过度使用，影响了土壤适宜性和可持续性。针对各种土地用途进行详细的土壤特性描述和土地评价是实现粮食安全和维持环境的重要步骤。本研究使用联合国粮食及农业组织（FAO）土地评估框架和层次分析法（AHP）模型对土壤进行分类，并评估其对番茄种植的适宜性。将土地利用需求与土地适宜性标准相匹配，并使用层次分析法（AHP）确定每个评价标准的相对重要性。分析了不同土地用途下土壤的形态和理化性质。根据美国农业部土壤分类法，土地用途HK1下的土壤被确定为典型内陆潜育土，HK2为典型白浆潜育土和雏形弱发育湿润淋溶土，而HK3则归类为典型弱发育湿润淋溶土和典型网纹潜育土。世界土壤资源参考分类系统将这些土壤分别确定为土壤单元HK1的潜育土、土系HK2P1的淋溶土，以及其余土壤单元的铁铝土。本研究证明了层次分析法在多标准方法中逻辑确定多个参数权重方面的有效性。结果表明，89.73%的区域非常适合番茄种植，而10.27%为中等适宜。这些土壤的主要限制因素是肥力低和排水不良。该研究表明，需要采用包括添加有机质、无机肥料和改善排水条件在内的管理技术来实现可持续生产力。
