针对突发公共卫生事件中的公园管理政策,以1月
24日的南京关闭公园景点规定为例,通过结合流行病学、公共
卫生、旅游、人口迁徙、绿地可达性多个专业领域数据及分析
方法,基于OD矩阵角度比较不同出行方式和传染期对政策执
行效果的影响差异。研究发现:1)及时关闭重要公园景点可能
使93%研究范围免于被传染,被传染人数下降62%~3 125%,
并间接减少重症病例;2)车行相较步行,传染区总面积增加
614%,高危区增加317倍,出行人口中公交比例越高,关闭
公园政策降低的染病率越高;3)步行、自行车传播与居民点
和公园入口最近距离有关,车行与居民点人口总数有关,各城
市需重点监控区域不同;4)节假日背景下,公园封闭政策应
该在进入社区传播前执行,否则效果大大降低。重要公共场所
和公交管控应作为同期政策,一并推出。 |

Abstract: |
The study aimed at park management in public health
emergencies. Taking the relevant regulations of Nanjing on
January 24 as an example, the data and analysis were carried out
based on the combination of epidemiology, public health, tourism,
population migration, and green space accessibility. By comparing
the differences of various possible strategies based on the OD
matrix, findings were concluded as follows: closing important park
attractions in time may save 93% of the research area from being
infected and reduce the number of infected patients by 62%-3125%,
indirectly reducing severe cases. The area of mobile transmission
increased by 614%, and the high-risk areas increased by 317 times
compared with walking transmission. The higher the proportion
of bus and car trips, the more they can benefit from the policy of
closing the park. Thirdly, walking transmission is mainly related to
the closest distance between residential areas and park entrances,
while mobile transmission is related to the total population of
settlements much more. For different travel proportions, the areas
to be monitored should also be different. Fourthly, in the context
of holidays, the park closure policy should be implemented before
entering the community spread stage. Otherwise the effect will be
greatly reduced. At the same time, the research points out that the
management and control of important public places like public
parks and public transport management should be launched as a
concurrent policy. |
