英文摘要	This article presents the results of spatial analysis of gastric cancer and its relation to environmental conditions in Shenqiu County, China. Retrospective data on gastric cancer mortality (GCM) were analysed at various spatial scales, with its relation to environmental factors explored at an appropriate scale. The results considered 2x2km(2) grid as the optimal level for characterising GCM due to the highest Moran's I (I=0.68, p<0.01). Then, three clustering regions were clearly identified. Meanwhile, GCM was obviously associated with topography (r=-0.11, p<0.10), farmland (r=0.11, p<0.10), population density (r=0.10, p<0.10) and river density (r=0.11, p<0.10) in the buffered zones. It indicates that spatial grid technique is suitable for characterising GCM in Shenqiu County, and that GCM was geographically associated with environmental conditions. We suggest that preventive measures for controlling the environment-related malignant neoplasm should not be limited in the regions suffering from this disease but be reasonably extended to surrounding areas.
