摘要:

以浙江龙游县北部地区为例,基于《土地质量地球化学评估技术要求》,选择1件/4 km2、1件/km2和4件/km23种采样密度,开展了土地质量地球化学评估工作,重点比较了不同采样密度下的土地质量地球化学评估结果的差异以及其结果的应用范围。结果显示,1件/4 km2的评估结果可以为省级土地管理服务,4件/km2的评估结果可以为县市级土地资源保护与开发利用服务,并指导乡镇级土地管理与土地质量地球化学评估工作的开展。该研究为今后开展土地质量地球化学评估工作提供了实践和理论基础。

Abstract:

According to “Land Quality Geochemistry Appraisal Specification”,this article carries out the land quality geochemical assessment about soil samples in Longyou County, Zhejiang Province in three kinds of sampling densities, which are 1 piece/4 km2, 1 piece/km2 and 4 pieces/km2.  Our works focus on the differences comparison and application areas of the results of land quality geochemical assessment. The results show that the density of  1 piece/4 km2 can serve for the land management in provincial level, and the density of 4 pieces/km2 can help for the protection and development of land in county city level,and also can instruct the land management and practice of land quality geochemical assessment in village and town level. This research provides a practical and theoretical foundation for the development of land quality geochemical assessment in future.

Key words: different sampling density, land quality, geochemical assessment, Longyou County of Zhejiang Province
