- 摘要:
- 2020年初新冠肺炎疫情暴发,并在全国大范围广泛传播扩散,根据31个省(自治区、直辖市)和新疆生产建设兵团报告的病例数据,将2020年上半年中国大陆新冠肺炎疫情期间天然氧吧地区与其他地区的累计确诊人数进行比较,并采用相关性分析计算氧吧所属地与其省会城市的距离、氧吧所属地海拔高度和COVID-19病例的关系。研究结果表明:(1)截至2020年7月5日中国新冠肺炎疫情可分为5个阶段:第一阶段仅武汉市确诊病例数从第9天开始迅速增加,氧吧地区未有病例报道; 第二阶段各氧吧地区平均累计确诊人数的增长率低于同类型城市; 第三阶段氧吧地区的首次清零时间大部分早于其他城市地区,且历时天数也较短; 第四阶段境外输入病例对氧吧地区的波及很小,氧吧所属市仅占6.15%; 第五阶段氧吧地区与其他地区相比并未出现反弹病例。(2)氧吧所属地与其省会城市的距离和COVID-19累计确诊人数呈负相关性,但在统计意义上体现不明显。(3)氧吧所属地的海拔高度和COVID-19累计确诊人数呈显著负相关性,其相关系数为-0.52,即随着海拔高度升高,氧吧所属地COVID-19确诊人数随之下降。总的来说,这些分析结果均表明氧吧地区的新冠肺炎疫情总体上轻于其他同类型城市,它们所显现出的疫情低风险特征有利于当地康养旅游(居)发展。
- Abstract:
- Since the outbreak of Coronary Virus Disease 2019(COVID-19)in early 2020, it has spread across the country. The risk status of the oxygen zone area is concerned. According to the case data reported by 31 provinces(autonomous regions and municipalities directly under the Central Government)and the Xinjiang Production and Construction Corps, the cumulative number of confirmed cases in the natural oxygen zone area during the COVID-19 epidemic in mainland China in the first half of 2020 was compared with other regions, and correlation analysis was used to calculate the relationship between the distance between the oxygen zone and its provincial capital and the COVID-19 cases, the relationship between the altitude of the oxygen zone and the COVID-19 cases. The results showed that:(1)As of July 5 2020, the COVID-19 epidemic in China can be divided into five stages: in the first stage, only the number of confirmed cases in Wuhan City increased rapidly from the 9th day, and no cases were reported in the oxygen zone area. In the second stage, the growth rate of the average cumulative number of confirmed cases in each oxygen zone area was lower than that of cities of the same type. In the third stage, the first clearing time of the oxygen zone area was mostly earlier than that of other urban areas, and the duration was also shorter. In the fourth stage, the impact of imported cases from abroad to the oxygen zone area was very small, with only 6.15% of the city where the oxygen bar belongs. In the fifth stage, there were no rebound cases in the oxygen zone areas compared with other areas.(2)The distance between the city where the oxygen zone is located and its provincial capital city was negatively correlated with the cumulative number of COVID-19 confirmed cases, but it was not statistically significant.(3)The altitude of the city where the oxygen zone belongs was significantly negatively correlated with the cumulative number of confirmed COVID-19 cases, with a correlation coefficient of -0.52. That is, as the altitude increases, the number of confirmed COVID-19 cases in the oxygen zone area decreases. In general, these analysis results indicate that COVID-19 in the oxygen zone area is generally lighter than other cities of the same type, and the low risk characteristics of the epidemic are conducive to the development of local health tourism(residential).
