以发病数和发病率为依据,利用ArcGIS 10.3软件和地理探测器,探究湖南省2020-01-21—02-28间COVID-19疫情的时空变化及其影响因素,结果显示:1)疫情演变具有时序阶段性。湖南省COVID-19流行过程可分为扩散期—鼎盛期—衰减期—消亡期4个阶段;所有发病县区中84.47%的首发病例为武汉输入。2)疫情传播具有交通依赖性。确诊患者和高发病率地区集中在铁路干线附近,"地级市早发、主城区多发"特征明显。3)疫情程度具有距离衰减性。邻近武汉的湘中、湘北、湘东北地区发病数和发病率最高。4)疫情分布具有空间集聚性。发病数和发病率集聚水平先增大后保持高位,疫情热点区位于长株潭及岳阳市,冷点区位于湘西州...

The COVID-19 epidemic spread globally at the start of 2020, resulting in a wide range of diffusion of infectious diseases. At present, SARS-CoV-2 is still prevalent worldwide, and it is of great practical significance to strengthen the study on the COVID-19 epidemic. Based on the COVID-19 confirmed cases and incidence, this article explored both the temporal and spatial distribution pattern of COVID-19 in Hunan Province and its influencing variables between January 21 and February 28, 2020 by using ArcGIS 10.3 and GeoDetector. The results show that: 1) The epidemic evolved with temporal phasin...
