平南县耕地质量等级评价摘要：【目的】以F港市平南县耕地为研究对象，建立县域耕地质量等级评价体系，为耕地利用和可持续发展提供参考依据。【方法】利用平南县土地利用、高分遥感影像等数据，在GIS平台采用国家土肥部门的耕地质量评价技术，进行2021年耕地质量评价研究。【结果】平南县耕地质量平均等级为5.5，其中一等地占比为0.31%，二等地占比为0.32%，三等地占比为3.33%，四等地占比为13.87%，五等地占比为32.82%，六等地占比为32.21%，七等地占比为12.Og%，八等地占比为3.73%，九等地占比为1.08%，十等地占比为0.24%。【结论】“十二五”期间，平南县耕地质量等级有所提升，障碍类型中无明显障碍型占比60%以上，但中等级耕地占比达到了78.90%，表明平南县耕地质量有较大的提升空间。【建议】针对瘠薄培肥型、灌溉改良型、渍潜稻田型等耕地，应加大资金、技术和物资投入力度，增强土地生产能力，提高耕地产出率，实现社会和自然可持续发展。关键词：耕地质量等级评价;Gls技术;平南县;耕地质量提升：F323.211文献标识号：A：1003-4374（2021）06-0064-07EvaluationofCultivatedLandQualityGradeinPingnanCountyMingXue，HuangZhi-gang（CollegeofAgriculture，GuangxiUniversity，Nanning，Guangxi530004.China）Abstract：[Objective]TakingthecultivatedlandinPingnanCounty，GuigangCityastheresearchobject，thequalityevaluationsystemofcultivatedlandqualitygradeinthecountyareawasestahlishedtoprovidereferenceforthecultivatedlandutilizationandsustainabledevelopment.[Method]Basedonthedataoflanduseandhigh-resolutionremotesensingimageinPingnanCounty，thecultivatedlandqualityin2021wasevaluatedbyusingthecultivatedlandqualityevaluationtechnologyofnationalsoilandfertilizerdepartmentinGISplatf'orm.[Result]TheresultsshowedthattheaveragegradeofcultivatedlandqualityinPingnanCountywas5.5，amongwhichtheproportionoff'irstclasslandwas0.31%.Thesecondclassaccountedf'or0.32%.Thethirdclassaccountedfor3.33%.Thefourthlevelaccountedfor13.87%.Thefifthlevelaccountedfor32.82%.Thesixthlevelaccountedfor32.21%.Theseventhlevelaccountedfor12.Og%.Theeighthlevelaccountedfor3.73%.Theninthlevelaccountedfor1.08%.Thetenthlevelaccountedfor0.24%.[Conclusion]Duringthe12thFive-Yearplan，thequalityof'cultivatedlandinPingnanCountyhasbeenimproved.Amongtheobstacletypes，noobviousobstacleaccountedformorethan60%.buttheproportionofmedium-gradecultivatedlandreached78.90%.whichshowthatthecountycultivatedlandqualityhasgreatroomtoimprove.[Suggestion]Theinvestmentofcapital，technologyandmaterialsshouldbeincreasedforbarrenfertilizingtype，improvedirrigationtypeandpaddyfieldtype，soastoenhancetheproductivityofland，improvetheyieldrateofcultivatedlandandrealizethesustainabledevelopmentofsocialandnaturalresources.Keywords：cultivatedlandqualitygradeevaluation，GIStechnology，PingnanCountyimprovedqualityofcultivatedland
