Abstract：The spatial agglomeration of cancer cases is the result of the evolution of man-land relationships， which cause public health problems that are of particular concern to social groups. In this study the number of cancer cases of residents are extracted based on the records of residents in the case area， and the spatial distribution of cancer residents are described based on geospatial analysis and kernel density. The spatial aggregation characteristics of patients are explored， and the relationship between external environmental factors and the spatial distribution characteristics of cancer cases is interpreted by geospatial statistics. The results showed that the aggregation of cancer patients in the case area was obvious with significant regional differences， presenting a multi-center， concentrated distribution pattern on the whole. The kernel density analysis suggested that cancer incidence was concentrated in the lower reaches of rivers， township industrial areas and chemical plant clusters. The distance from the settlement point to the chemical plant greatly affected the occurrence of cancer， and the areas where medical facilities are inadequate have a certain impact on the incidence of cancer. The high incidence of cancer is mostly distributed within 5 km from the river. The results verified the impact of environmental pollution and medical level on the health of residents， providing references for related environmental pollution remediation work and environmental and population monitoring.
