摘要
新冠肺炎疫情对各地经济水平、居民健康和生活等产生深刻影响。综合运用空间自相关分析、最近邻指数、核密度估计、冷热点分析等方法分析湖南省疫情的演变趋势、空间分异特征等。结果表明:湖南省疫情防控工作及时有效,治愈率高于全国平均水平;确诊人数日均增长率与迁入规模指数变化趋势一致,严格管控人口流动能有效降低疫情传播;确诊病例数总体呈现空间正相关集聚,高值主要集聚在长沙市中心城区、岳阳市的云溪区和岳阳楼区;确诊小区呈现"一主四副"的显著凝聚分布态势,不均衡分布特性明显;疫情热点在长沙市中心城区和岳阳市北部,冷点在湘西州吉首市。
The COVID-19 epidemic has seriously affected economic standards,people’s health and their lives.Spatial autocorrelation analysis,nearest neighbor index,nuclear density distribution,cold and hot point analysis were used to analyze the evolution trend,spatial differentiation characteristics of Hunan COVID-19 epidemic situation.The results showed that the epidemic prevention and control work in Hunan Province was timely and effective,the cure rates was above the national level.The daily growth rate of the confirmed population was consistent with the migration scale index,and controlling population flow could effectively curb the spread of the epidemic,the high value was mainly concentrated in central urban area of Changsha City,Yunxi District and Yueyanglou District of Yueyang City,the confirmed community showed a significant cohesion distribution,unbalanced distribution characteristics.The epidemic hot spots in central urban area of Changsha and northern Yueyang,the cold point in Jishou City of Xiangxi Prefecture.
