摘　　要：目的了解和掌握2016—2021年黑龙江省华支睾吸虫人群感染状况及空间分布特征,为制定防控策略提供科学依据。方法收集2016—2021年黑龙江省华支睾吸虫病监测数据,对华支睾吸虫感染人群分布特征进行描述性分析,结合空间自相关分析和核密度估计等空间流行病学统计方法探索研究区域华支睾吸虫病的空间分布特征。结果2016—2021年黑龙江省华支睾吸虫病监测覆盖71个县(市、区)、417个村(社区),华支睾吸虫总感染率为3.91%(4488/114905)。感染人群以男性(64.46%,2893/4488)、40~59岁(58.53%,2627/4488)、初中文化(52.01%,2334/4488)、汉族(95.45%,4284/4488)、农(牧、渔)民(92.96%,4172/4488)为主。男性(4.92%,2893/58764)感染率高于女性(2.84%,1595/56141);40~49岁组、50~59岁组人群感染率分别为5.71%(1358/23785)、5.32%(1269/23867);初中、高中人群感染率分别为4.00%(1553/38812)、4.52%(2334/51582);农(牧、渔)民人群感染率为5.11%(4172/81614);朝鲜族、蒙古族人群感染率分别为12.85%(163/1268)、9.26%(34/367);不同性别、年龄组、文化程度、职业、民族感染率差异有统计学意义(χ2=331.598,χ2=855.526,χ2=281.391,χ2=1522.040,χ2=337.219,均P<0.05)。以县(市、区)为单位对华支睾吸虫人群感染率进行全局空间自相关分析显示,研究区域存在呈聚集性分布(Moran's I=0.414,Z=5.115,P=0.001);局部空间自相关分析显示,高–高聚集区域主要是分布于省内东北部。以村(社区)为单位进行全局空间自相关分析显示研究区域华支睾吸虫感染存在聚集性分布(Moran's I=0.437,Z=15.897,P=0.001);局部空间自相关分析显示,呈高–高聚集的村(社区)数为43个,主要分布于省内东北部及西南部,呈高–低聚集的村(社区)数为1个,分布于省内东北部。核密度估计显示,核密度高值区纵向分布于省内东北–西南部,主要呈现沿松花江流域分布的特征。结论黑龙江省华支睾吸虫病分布具有明Objective To understand the population and spatial distributions of Clonorchis sinensis infection in Heilongjiang province from 2016 to 2021,and provide scientific evidence for the prevention and control of Clonorchiasis.Methods The surveillance data of Clonorchiasis in Heilongjiang from 2016 to 2021 were collected for a descriptive analysis on the distribution of the population infected with Clonorchis sinensis.Spatial autocorrelation analysis and nuclear density estimation were used to explore the spatial distribution of Clonorchis sinensis infection in the study area.Results The surveillance for Clonorchiasis covered 71 counties(districts)and 417 villages(communities)in Heilongjiang from 2016 to 2021.The overall infection rate of Clonorchis sinensis was 3.91%(4488/114905).The infection cases were mainly men(64.46%,2893/4488),people aged 40-59 years(58.53%,2627/4488),people with junior high school education(52.01%,2334/4488),people in Han ethnic group(95.45%,4284/4488)and farmers(herdsmen,fishers)(92.96%,4172/4488).The infection rate in men(4.92%,2893/58764)was higher than that in women(2.84%,1595/56141).The infection rates were 5.71%in age group 40-49 years(1358/23785)and 5.32%in age group 50-59 years(1269/23867).The infection rates in junior high school and senior high school students were 4.00%(1553/38812)and 4.52%(2334/51582),respectively.The infection rate in farmers(herdsmen and fishers)was 5.11%(4172/81614).The infection rates in Chinese Korean and Mongolian populations were 12.85%(163/1268)and 9.26%(34/367),respectively.There were significant differences in infection rate of Clonorchis sinensis among different sex,age,education level,population and ethnic groups(χ2=331.598,χ2=855.526,χ2=281.391,χ2=1522.040,χ2=337.219,all P<0.05).The global spatial autocorrelation analysis on the infection rate of Clonorchis sinensis in population showed that there was clustering at county level in the study area(Moran's I=0.414,Z=5.115,P=0.001).Local spatial autocorrelation analysis showed that the high-high cluste
