摘要
According to "Land Quality Geochemistry Appraisal Specification", this paper 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. The 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.
