摘　　要：为详细了解潜山市土壤质量地球化学分布状况,科学合理地利用规划土地资源,运用潜山市土地质量地球化学调查数据,对潜山市土壤质量进行地球化学评价和研究。结果表明:研究区土壤养分综合等级以中等和较缺乏为主,占研究区面积的88.70%;区内土壤整体具有缺Cu,少B、Co、V、Mn、Mo及富Zn的特点;土壤环境质量以无风险为主,占研究区面积的96.89%,风险可控区占研究区面积的3.06%,风险较高区土壤分布面积较小,且为人为工业污染所致;区内土壤质量综合等级以良好、中等为主,分别占研究区面积的47.41%和41.36%,优质土壤较少,占研究区面积的8.36%;区内土壤Se以适量和边缘为主,富Se土壤面积较少,仅占评价区面积的4.98%。评价成果对潜山市土地利用规划、基本农田建设、农业种植结构调整、特色农业发展及生态环境保护等具有指导意义。In order to understand the geochemical distribution of soil quality in Qianshan City in detail,and uti-lize land resources scientifically and rationally,the authors in this paper adopted geochemical survey data for land quality to conduct geochemical evaluation and survey of soil quality in Qianshan City.The results show that the comprehensive level of soil nutrients of the study area is mainly medium or relatively deficient,accounting for 88.70%of the total area of the study area.The overall level of soil nutrients in the study area is deficient in Cu,low in B,Co,V,Mn,Mo and high in Zn.The soil environmental quality is mainly risk-free,accounting for 96.89%of the study area,and the risk-controlled area accounts for 3.06%of the study area.The high-risk soil distribution area is small,and it is caused by human-made industrial pollution.The comprehensive grade of soil quality in the area is mainly good and medium,accounting for 47.41%and 41.36%of the study area respec-tively,and the good quality soil is less,accounting for 8.36%of the study area.The selenium content in the soil is moderate and marginal,and the selenium rich soil area is small,accounting for only 4.98%of the study area.The assessment results could provide references for land use planning,basic farmland construction,agricultural planting structure adjustment,distinctive agricultural development and ecological environment protection in Qians-han City.
