摘　　要：基于商丘地区多目标区域地球化学调查成果数据,参照土地质量地球化学评价规范,对商丘地区进行了土地质量地球化学评价及空间分布研究。结果表明:商丘地区土地质量状况整体良好,优质级土地面积为9573 km^2,占总面积的97. 1%;良好级土地面积为275 km^2,占总面积的2. 80%;中等及差等土地面积为12. 60 km^2,占总面积的0. 12%,零星分布在永城县及民权县。土地质量地球化学评价可为土地质量生态管理和土地合理规划、利用提供依据。Based on the Multi-Purpose Geochemical Data.Referring Land Quality Geo-chemical Assessment Protocol,the geochemical land evaluation and space distribution in Shangqiu area have been researched.The results demonstrate that land quality in the researched area is in good condition,the area of superior-level land is 9573km^2,accounting for 97.1% of the study area.the good-level land accounts for 2.80%,the medium-level land and the poor-level land accounts for 0.12%,mainly distributed in Yongcheng town and Minquang town.The land quality assessment could provide a scientific basis for ecological management of land quality and rational planning of land use.
