摘　　要：目的了解2021年枣庄市生活饮用水水碘含量及空间分布特点,为预防碘缺乏病提供科学依据。方法收集2021年枣庄市居民生活饮用水水碘含量相关数据,采用SPSS 19.0和ArcGIS 10.2进行流行病学和空间相关分析。结果2021年枣庄市64个乡(镇、街道、办事处)1051个行政村(居委会、社区)的1090份生活饮用水样中,碘含量中位数为5.38μg/L,水碘含量<10μg/L的水样897份,占82.29%,属于外环境碘缺乏地区。地理空间相关性分析显示,水碘含量全局分布存在正空间自相关性(Moran’sI指数=0.22,Z=3.31,P<0.05)。7个乡(镇、街道)居民饮用水水碘含量局部自相关检验差异有统计学意义(P<0.05),呈现两种聚集模式,其中陶庄镇、常庄街道办事处、临城街道办事处、沙沟镇和兴仁街道办事处5个乡镇为高-高聚集模式,善南街道办事处和各塔埠街道办事处为高-低聚集模式。结论枣庄市大部分乡镇为碘缺乏地区,水碘分布存在空间聚集现象,局部空间分布存在空间异质性,需要坚持长期补碘的防控措施。Objective To understand the iodine content of drinking water and spatial distribution characteristics in Zaozhuang City in 2021,and to provide scientific evidence for preventing iodine deficiency disorders.Methods The data on the iodine level of drinking water were collected in Zaozhuang City in 2021,and SPSS 19.0 and ArcGIS 10.2 were used to analyze the epidemiological and spatial correlation.Results A total of 1090 drinking water samples were collected from 1051 administrative villages(neighborhood committees and communities)in 64 townships(towns,streets,offices)in Zaozhuang City in 2021,the median water iodine was 5.38μg/L,and there were 897 water samples whose water iodine was lower than 10μg/L,accounting for 82.29%,belong to the environmental iodine-deficient area.Spatial autocorrelation correlation analysis showed that there was a positive spatial autocorrelation in the global distribution of water iodine content(Moran’s I=0.22,Z=3.31,P<0.05).The local autocorrelation test of io dine content in drinking water of residents in 7 townships(towns,streets)showed statistically significant differences(P<0.05),showing two aggregation modes,5 areas including Taozhuang Town,Changzhuang Sub-district Office,Lincheng Sub-district Office,Shagou Town and Xingren Sub-district Office were in the high-high aggregation mode,2 areas in cluding Shannan Sub-district Office and Getabu Sub-district Office were in the high-low aggregation mode.Conclusion Most of the towns in Zaozhuang City are iodine-deficient areas.There is spatial aggregation in the distribution of water iodine,and there is spatial heterogeneity in the local spatial distribution.It is necessary to adhere to the prevention and control measures of long-term iodine supplementation.
