| Abstract: | With the aid of the Geographical Information System (GIS) and Geostatistics, distribution and spatial variability of soil Pb in Huludao City was investigated. Based on the monitoring data with the Kringing method, single-factor evaluation of Pb pollution was carried out, a spatial distributed map of soil Pb was plotted out and Pb contamination index of the region worked out. On such a basis, criteria for evaluation of soil Pb pollution was explored. |
