摘要
为了展现2020年1月20日到3月14日之间湖北省各地新型冠状病毒肺炎的时空变化情况并探索其影响因素,利用核密度分析、空间自相关分析以及相关性分析等方法直观定量地展示新冠病毒疫情在湖北省的时空变换过程和其相关影响因素.得到以下主要结论:1)湖北省确诊人数空间变化上呈现东高西低的状态.2)新冠肺炎初期分布为一核强集聚,聚集核心为武汉和鄂州交界处,多核弱集聚;后期弱聚集区域逐渐缩小减少,强聚集区逐渐分化为武汉和鄂州两个聚集核心.3)湖北省西部大部分县市呈现低-低聚集的态势,东部以武汉市为核心与相邻县市形成高-高相邻或高-低相邻.4)交通因子对新冠肺炎确诊人数的空间分布具有较大的影响,其次与新冠病毒传播和发展有显著相关性的因素是地形因素和当地的社会环境.
In order to present the spatial-temporal changes of COVID-19 and explore its influencing factors across Hubei Province(from January 20 to March 14,2020),the change were intuitively and quantitatively demonstrated by using nuclear density analysis,spatial autocorrelation analysis and correlation analysis.The main conclusions are as follows:1)The number of confirmed cases in Hubei Province is higher in the East and lower in the West.2)The initial distribution of COVID-19 was characterized by a strong nuclear cluster and a weak multicore cluster.In the later period,the weak aggregation area gradually decreased and the core cluster was split in two centered in Wuhan and Ezhou.3)Most of the Counties and Cities in the western part of Hubei Province presented the trend of low-low aggregation,and the eastern part took Wuhan City as the core and formed high-high or high-low neighborhood with neighboring Counties and Cities.4)Traffic factors had a significant influence on the spatial distribution of the number of COVID-19 diagnosed.Topographic factors and local social environment related to the novel Coronavirus transmission and development significantly too.
