Langfang City, Hebei Province is known as the “Pearl on the Beijing-Tianjin Corridor”, it is an important city in the Bohai Economic Circle. In the process of land use information collection for key enterprises in soil pollution, by interviewing local residents on site, the authors have obtained information on cancer morbidity and mortality 45 groups that by the village as a unit. The Cancer distribution map was drawn using the Geographic Information System MapGIS operating platform. According to urban environmental geochemical surveys and multi-target geochemical survey data, the author conducted a related analysis. The results show that the residents cancer morbidity and mortality are negatively correlated with the depth of shallow groundwater table, γ = -0.5271, (n = 45, γ0.05 = 0.2040), significant positive correlation indicators: deep soil Hg0.8885, surface soil Pb0.8572, shallow groundwater Cr0.8290, deep soil N0.7106, surface soil effective Zn0.7027, surface soil Cd0.6931, Hg0.6751, shallow ground water NH4-N0.6441, surface water Zn0.6288, shallow ground water As0.6206, NO3-N0.6130, Pb0.5284, Cd0.5028, NO2-N, 0.4958. According to the characteristic pollutant frequency table of 340 key industries in Langfang area, these organic matters significantly related to mercury: benzopyrene 0.4723, pyridine 0.1551, formaldehyde 0.1371, dioxin 0.1138.According to the results of this research, the authors established a map of the relationship between water soil geochemical anomalies (contamination sources) and geotechnical hydrological conditions (migration pathways) and resident cancer distribution (sensitive receptors).
