摘　　要：土地质量是土地管理、农业发展和环境保护的前提,土地质量评估是打造现代农业,保护生态环境,实现土地"质量型、生态型"管理的一项基础性地质调查工作。本文根据上海地区现有工作程度,详细介绍了全市、典型县区土地质量评估工作,结合正在开展的乡镇级土地质量评估工作,分析了不同工作比例尺土地质量地球化学评估工作中评估单元、评估指标、评估标准等的异同,为进一步开展相关工作奠定基础。Land quality is the starting point for all land management, agncultural development, and environmental protection activities. Land quality assessment requires basic geological survey work to facilitate modern agncultural development, as well as ecological and environmental protection. Based on the extent of the existing work in Shanghai, classified introducing the city, the typical county land quality assessment. By considenng the ongoing work of township-level land quality assessment, the paper analyzes the similarities and differences among evaluation units, evaluation indicators, and evaluation standards at the different working scales of geochemical assessment, and lays the foundation for further related work.
