| 应用空间自相关分析研究广西壮族自治区肝癌的空间分布特征。方法利用全区2000-2007年肝癌资料，求出各市县肝癌8年平均发病率；应用地理信息系统中的空间统计分析模块进行空间自相关分析。 |
| 英文摘要: |
| study the spatial distribution characteristics of liver cancer in Guangxi so as to provide evidence for the development of congol and prevention on liver cancer.Methods The average eight year morbidity was computed,using the rates of liver cancer in 2000-2007.The spatial statistics module of GIS was used to conduct spatial autocorrelation analysis.and the disease mapping Was drawn,using the Map Info 8.0 software.Results The average morbidity rate Was clustered in Guangxi in the past eight years.with Moran's I index as 0.34 and P value below 0.01.G index appeared to be 0.77 and the Pvalue Was below 0.01.Moran's I correlogram lifled up in four spaces,specifically,the cluster took place in both nlacro-scale(one to three spatial intervals,45 to 135 km real Scale)and micro-scale(16 to 18 spatial intervals,720 to 800 km real scale).When the spatial interval became 14 and real scale was 60 km.the spatial distribution of liver cancer showed the most intensive autocorrelation.Most of the regions with high morbidity would be clustered in the southwest and southern parts,along the Coastal areas of Guangxi while the regions with low morbidity clustered in the northern part of Guangxi.Conclusion Liver cancer was found un-randorely distributed and geographitally clustered in Guangxi in 2000-2007. |
