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 ,可指导相应防制措施的实施
Objective To study the spatial distribution of malaria in Hainan Province. Methods The incidence of malaria in cities and counties of Hainan Province from 1995 to 1999 was collected. With the help of ArcGIS 8.1 software, a geographic information system for malaria in Hainan Province was established. Based on this, a local interpolation analysis was established to establish Hainan Province Malaria spatial distribution map, select unbiased optimal spatial distribution map based on cross-evaluation index. Results The spatial distribution of malaria in Hainan Province from 1995 to 1999 showed that the incidence of malaria in southern China was significantly higher than that of northern China. The incidence of southern malaria was mainly concentrated in Wuzhishan and Yinggeling Mountains, and the incidence of malaria in the eastern coast was generally higher than Western coast. Cross-assessment indicators show that the established malaria spatial distribution map of Hainan Province is an unbiased optimal estimation of malaria distribution in Hainan Province. Conclusion Spatial local interpolation method can well estimate the spatial distribution characteristics of malaria in Hainan Province and guide the implementation of corresponding control measures
