随着国家对土地数量、质量、生态全方位管护要求的逐渐明确和加强，中大比例尺土地质量地球化学调查与评价成果在永久基本农田保护、土地利用规划编制等国土资源管理工作中的落地应用需求日趋迫切。本文以上海市金山区廊下镇1：10000实际调查数据的795个图斑（自然地块）为例，对比分析了1：50000空间插值结果与1：10000实测结果的相对误差、土地质量等级的变化情况，开展了1：50000土地质量地球化学调查与评价成果转化应用的探索性研究。

Alongside the strengthening of management policies for land quantity, land quality, and ecological protection, the Geochemical Survey and Evaluation on Land Quality has an important role in mid- and large-scale land and resource management. Data from 795 patches (natural plots) at a scale of 1:10,000 in the town of Langxia in the Jinshan district, Shanghai, is used as an example for studying the relative error and geochemical land quality changes. Spatialy interpolated data from the Geochemical Survey on Land Quality (at a scale of 1:50,000) is also used to implement land and resources management.
