Abstract：[Purposes] By utilizing reasonable soil profile sampling point design and scientific sampling methods，it is possible to efctively reflect the enrichment characteristics of soil gold elements，deepen the exploration of the distribution pattern of gold deposits，and promote sustainable development of resources in the region.[Methods] Taking the design and sampling method of 1 ÷ 1 0 000 soil profile sampling points in Taoyuan Gold Mine，Jiangxi Province asan example，acomprehensive analysis of the geological characteristics and distribution of gold mines in the mining area was conducted.Based on previousresearch results，geological background，and gold anomaly area data from 000water system sediment measurements，a 2O km soil profile was set up.Before sampling，the GPS was calibrated and the main sample point was determined based on the GPS point coordinates and a sub sample and the main sample at a distance of 2～5 m before and after the profile line to were took form a three in one sample.[Findings]Based on 4O6 soil samplessampled in the field，preliminary analysis showed that there were significant differences in gold content at different depths and at different sampling sites. These differences may be closely related to the physicochemical properties of the soil （such as soil pH， particle composition，nutrient content，etc.），the distribution of ore bodies and their enrichment mechanisms.[Conclusions] Reasonable sampling design and scientific sampling method can effectively reflect the distribution characteristics of gold in soil.
