Characteristics and effective utilization of natural zinc-enriched land resources in Shicheng County of Ganzhou City, Jiangxi Province

China Geological Survey carried out a 1:50000 land quality geochemical survey covering an area of 400 km² in Shicheng County, Ganzhou, to support poverty alleviation in six counties of Ganzhou, and finally delineated a total area of 85.48 km² of zinc-rich soil.On the basis of geochemical survey, the content and spatial distribution of zinc in soil, soil quality and fertility, air quality and irrigation water quality in Shicheng County were systematically studied.Based on the spatial distribution of soil parent material and the characteristics of zinc content, the origin of zinc in soil was investigated, and the corresponding relationship between parent material and zinc content in soil was verified.By combining the natural zinc-rich land resources with regional agriculture, local tourism and geological culture village in Shicheng County, some suggestions on the development and utilization of zinc-rich land resources were put forward, which provided scientific support for the protection and efficient utilization of zinc-rich land resources in Shicheng County.
