摘　　要：在耕地质量等级更新评价基础上,对海口市耕地质量进行了综合评价与等级划分,系统论述了海南省海口市耕地质量状况,分析了耕地主要障碍因子并提出了改良措施.结果表明,海口市耕地质量加权平均等级为5.65,耕地质量整体属于中等偏下水平.建议在今后的耕地利用与保护工作中,不仅要合理选择作物和耕作模式、合理施用化肥、增施有机肥、补充微量元素,还应适当调节土壤酸度、实行水旱轮作、底肥浅施,从而削弱酸土、贫瘠土壤带来的不良影响.Based on the updated evaluation of cultivated land quality grade,this paper made a comprehensive evaluation and grade classification of cultivated land quality in Haikou,systematically discussed the quality of cultivated land in Haikou of Hainan province,and analyzed the main obstacle factors and improvement measures of cultivated land.The result showed that the weighted average grade of cultivated land quality in Haikou was 5.65,which indicated that the quality of cultivated land in Haikou was in the middle to lower level as a whole.It was suggested that in the future work of farmland utilization and protection,in addition to rational selection of crops and cultivation modes,rational application of chemical fertilizers,increased application of organic fertilizers,and supplementation of trace elements,the soil acidity should also be properly adjusted,and water and dry rotation and shallow application of base fertilizer should be implemented,so as to weaken the adverse effects of acid and barren soil.
