目的了解2008～2012年广西凌云县恶性肿瘤死亡率在镇（街道）、行政村（居委会）尺度上的空间分布及聚集性特征，为制定科学的恶性肿瘤防控策略提供依据。方法利用GIS空间分析技术对广西凌云县2008～2012年恶性肿瘤死亡率的分布特点和空间聚集性进行探测分析。结果凌云县以西南和东北部乡镇的恶性肿瘤死亡率最高，众多乡镇中只有朝里瑶族乡恶性肿瘤死亡率逐年递减，其他乡镇无明显变化。空间聚集半径随时间推移处在“先扩大后又缩小”的循环波动中，且疫情高发区处在“先向南后向北”的循环波动中。结论凌云县各乡镇及行政村的恶性肿瘤死亡率存在明显且不固定的高发区，建议相关部门加大对恶性肿瘤高死亡率所在区域的恶性肿瘤筛查力度，不断降低其死亡率，并根据疾病转移态势提前做好应对措施。

ObjectiveTo explore the characteristics of spatial distribution and aggregation of cancer mortality in size of town(street) and administrative villages (committees) in Lingyun , Guangxi from 2008 to 2012, and provide evidence for making prevention and control strategy of malignant tumor. MethodsDistribution and aggregation of cancer mortality in Lingyun from 2008 to 2012 was detected and analyzed by GIS analysis technology. ResultsThe cancer mortality of Lingyun was concentrated in some southwest and northeast towns and villages，and the cancer mortality inwardly diminishing only in ChaoliYao town, and it did not change significantly in other towns. The gathering radius expands first and then gradually narrowed over time, and the cyclical fluctuation of high incidence of the epidemic fluctuates was south first and then to the north. ConclusionsHigh cancer mortality in towns and villages of Lingyun are geographically clustered but not fixed, the relevant departments should strengthen the screening of cancer in high cancer mortality area to decrease cancer mortality and take some measures to prepare for the transfer trend of high cancer mortality areas in advance.
