摘要
目的 研究海南省疟疾空间分布特征。方法 收集 1 995～ 1 999年海南省各市 (县 )疟疾发病率资料 ,在ArcGIS 8.1软件支持下 ,建立海南省疟疾发病的地理信息系统 ,并以此为基础利用空间局部内插分析建立海南省疟疾空间分布图 ,以交叉评价指标为依据选择无偏最优的空间分布图。结果 1 995～ 1 999年海南省疟疾空间分布图显示 ,南部疟疾发病率显著高于北部 ;南部地区发病主要集中于五指山、鹦哥岭山脉为中心的地区 ,且东部沿海的发病率普遍高于西部沿海。交叉评价指标显示 ,建立的海南省疟疾空间分布图是对海南省疟疾分布的无偏最优估计。结论 空间局部内插法能很好估计海南省疟疾的空间分布特征 。
Objective To explore the spatial distribution of malaria in Hainan province. Methods Maps of spatial distribution on malaria incidence in Hainan province from 1995 to 1999 were produced,using a spatial local interpolation technique in the ArcGIS 8.1 software. Cross validation techniques were used to evaluate the fitness of the distribution maps. Results The spatial distribution of malaria in Hainan province from 1995 to 1999 showed that the incidence of malaria in the southern part of Hainan province were higher than that in the north. In the south, the incidence of malaria in east coastal areas were higher than that of other parts, especially in Wuzhi and Yingge mountains. The prediction error of the cross validation indicated that the spatial distribution maps of malaria in Hainan had good fitness of malaria incidence of Hainan province. Conclusion Spatial local interpolation technique seemed to be promising in describing the spatial distribution of malaria.
