Background: At present, the spatial studies of liver cancer are too large for observation, or lack systematic spatial epidemics and statistical analyses, so it is difficult to put forward more targeted regional prevention and control measures. This study takes the natural village of Longkou City, Shandong as a small regional research unit, to systematically analyze the spatial structure and spatial heterogeneity of liver cancer in the small region (village as a unit), and provide a scientific basis for the development of regional prevention and control measures for more targeted liver cancer and its related diseases. Methods: Based on the database of the integrated management information system for chronic diseases and death monitoring in Shandong Center for Disease Control and Prevention, the spatial epidemiology and spatial statistics methods were combined in the framework of geographic information system (GIS). Results: The results of spatial distribution showed that there was obvious spatial heterogeneity on liver cancer in Longkou City, and there were many high incidence and high death areas scattered in the distribution. The spatial scanning and space-time scanning results of liver cancer showed that there were relatively fixed high incidence and high death villages in the small area of Longkou City. Conclusion: This study suggests that the liver cancer in Longkou City has a local geographic risk factor, which may have obvious high incidence area, and time factors have a certain influence on the space area of liver cancer. It is necessary to further carry out the geographical weight regression and risk factors analysis, and expand the study model.
