四川省HIV/AIDS空间自相关分析

目的]探讨四川省HIV/AIDS发生与空间位置之间的关系。方法]采用全局空间自相关Moran’sI系数探测四川省HIV/AIDS的空间分布模式,采用局域空间自相关Gi*统计量探测聚集位置与属性。结果]2004年四川省HIV/AIDS整体上呈随机分布,HIV/AIDS有两个高发区,2005年四川省HIV/AIDS整体上呈聚集分布。探测出5个HIV/AIDS高发区。结论]四川省HIV/AIDS以凉山彝族自治州为中心,向整个四川省西南部扩张并呈现聚集分布。

THE SPATIAL AUTOCORRELATION OF HIV/AIDS IN SICHUAN

Objective] To discuss the relationship between the incidence of HIV/AIDS and the location in Sichuan Province. Methods] A global means of spatial autocorrelation with Moran's I was used to explore the whole spatial distribution pattern of the incidence of HIV/AIDS in Sichuan Province. The location and intensity of cluster was detected by applying the statistic which was one of many ways the local spatial autocorrelation. Results] The distribution of the incidence showed to be random in 2004 and was spatial clustered to some extend in 2005. There were two regions with high incidence of HIV/AIDS in 2004,while there were five in 2005. Conclusion] At present the distribution center of HIV/AIDS in Sichuan Province was Liangshan. The incidence revealed to be spatial clustered and expanded from the center to the southwestern region of Sichuan.
