目的探讨甘肃省4种主要自然疫源性疾病空间分布特征,掌握高发重点区域,为疫情防控提供理论依据。方法利用Flexible空间扫描统计量对甘肃省2009-2013年4种自然疫源性疾病进行空间扫描分析,通过地理信息系统呈现空间聚集区域。结果空间扫描结果显示,甘肃省4种自然疫源性疾病具有明显的空间聚集区域。其中,肾综合征出血热、布鲁氏菌病(布病)和炭疽主要集中在甘肃省东南部的湿润区,呈现出东南多西北少的特点,并且布病和炭疽高发区主要在农牧区。疟疾主要集中在甘肃省西部地区。结论 Flexible空间扫描软件与地理信息系统相结合可有效对甘肃省4种自然疫源性疾病的空间聚集性作出早期预警。
Objective To investigate the spatial distribution characteristics of four major natural foci of Gansu Province and to find out the key areas with high incidence and provide a theoretical basis for prevention and control of epidemic situation. Methods Spatial scanning analysis of four kinds of natural epidemic diseases in Gansu Province from 2009 to 2013 was conducted by means of Flexible spatial scanning statistics, and the spatial aggregation area was presented through GIS. Results The results of space scanning showed that the four natural foci of Gansu Province had obvious spatial agglomeration. Among them, hemorrhagic fever with renal syndrome, brucellosis (brucellosis) and anthrax are mainly concentrated in the moist area of southeastern Gansu Province, showing the characteristics of southeastern and less than northwest, and the high incidence of brucellosis and anthrax are mainly in agriculture and animal husbandry Area. Malaria is mainly concentrated in the western region of Gansu Province. Conclusion The combination of Flexible space scanning software and geographic information system can effectively early warning the spatial aggregation of the four natural foci of Gansu Province.
