Facing the epidemic situation of infectious diseases and other challenges posed on us by nature, how to build a more "resilient" modern city is a problem that we need to ponder deeply after this epidemic situation.

Improving the Public Health System

When the epidemic breaks out, an efficient modern public health system is a crucial "armor" for a city. "Public health is an art and science that prevents diseases, prolongs life span and promotes health through organized efforts of society", said Professor Wu Xifeng, dean of the School of Public Health of Zhejiang University.

Wu Xifeng said that a city should be prepared for any emergence from time to time and make good reserves to deal with public health emergencies. This includes not only the reserve of facilities and materials but also the reserve of talents that are easy to be neglected. Our current public health personnel reserve is still insufficient, and both quantity and quality need to be improved urgently. It is urgent to train more public health personnel with both theoretical basis and practical experience who can stand at the forefront of epidemic prevention after the outbreak.

The Living Environment is More "Resilient"

To build a healthy city, we must first build healthy buildings and healthy communities.

Taking the prevention and control of the epidemic as the breakthrough point, Professor Wang Zhu's team from Zhejiang University's School of Architecture and Engineering put forward the concept of building "safe and healthy units" in urban and rural areas. In order to improve the ability to deal with emergencies and public health events as the goal, grasp the "peacetime and wartime combination" of the urban and rural space environment and public service facilities, and provide a construction strategy and design method for building a safe and healthy community facing the future. The "Safety and Health Unit" is designed to maintain its self-reliance ability in the event of epidemic situations and disasters. Under the condition of less dependence on external support, its internal spontaneous formation has the organizational ability of self-help, mutual aid and rapid recovery of local functions.

On the other hand, each "safety and health unit" are interrelated and supportive of each other.

Improving Scientific Literacy

The resilience of a city is also reflected in the stable mentality of the citizens and the orderly society during the epidemic, which to a large extent depends on the scientific literacy, health literacy and civilized cultivation of each citizen.

The general recognition and cooperation of the broad masses to a series of government protective measures especially need the support of scientific literacy. The effective implementation of these protective measures mainly depends on individual consciousness, and social consensus cannot be formed without certain scientific cognition.

It is urgent to build a large ecological circle to enhance citizens' scientific literacy. This requires the efforts of all parties and making more scientists willing to do popular science work is very important.

Only in a social environment where people attach more and more importance to popular science will our citizens' scientific literacy continue to improve.

面对传染病疫情以及大自然带给我们的其他挑战，如何打造一个更具“韧性”的现代化城市，是经历了本次疫情后的我们有必要深思的问题。

完善公共卫生体系

疫情袭来，高效的现代公共卫生体系是一座城市至关重要的“铠甲”。“公共卫生是一门通过社会有组织的努力来预防疾病、延长寿命和促进健康的艺术和科学”。浙江大学公共卫生学院院长吴息凤教授说，.

吴息凤表示，一座城市在平时就要未雨绸缪，做好应对突发公共卫生事件的储备工作。这既包括设施储备、物资储备，也包括容易被忽视的人才储备。我们当前的公共卫生人才储备仍显不足，数量、质量均亟待提升，急需培养更多既有理论基础又有实践经验、能够在疫情发生后站在防疫第一线的公共卫生人才。

人居环境更具“韧性”

建设健康城市必先打造健康建筑、健康社区。

以此次疫情防控为切入点，浙大建筑工程学院王竹教授团队提出了建设城乡“安全健康单元”的概念，以提高应对突发重大灾害与公共卫生事件的能力水平为目标，把握城乡空间环境与公共服务设施的“平战结合”，为打造面向未来的安全健康社区提供一种营建策略和设计方法。“安全健康单元”的设计目标是在遭受疫情与灾害时保持自立能力，在不过分依赖外界支援的状态下，其内部自发形成具有自救、互救并快速实现局部功能恢复的组织能力。

另一方面，各个“安全健康单元”之间又是互相联系、互相支持的。

提升科学素养

一座城市的韧性，还表现在疫情期间市民心态安定、社会仍然有秩序，这很大程度上有赖于每一个市民的科学素养、卫生素养和文明修养。

广大群众对政府一系列防护措施的普遍认同与配合，尤其需要科学素养的支撑。这些防护措施的有效实施主要靠个体自觉，没有一定的科学认知是无法形成社会共识的。

构建提升公民科学素养的大生态圈是当务之急。这需要多方面发力，让更多的科学家乐于做科普工作是其中很重要的内容。

只有社会上下重视科普的氛围越来越浓，我们的公民科学素养才会不断提升。
