RESILIENCE OF URBAN MEDIAL FACILITIES SYSTEM NETWORK AND PLANNING STRATEGIES:A CASE STUDY OF THE MAIN URBAN AREA OF ZHENGZHOU
Given that the development of Chinese cities has entered a stage characterized by high risks,the resilience of the medical facilities system plays an important role in ensuring urban safety under the disturbance of uncertain pressure.Taking Zhengzhou as an example,this paper explores the planning methods for building a resilient urban medical facilities system.Firstly,based on the cascading and directional characteristics of the synergy between facilities,the paper identifies the resilience synergy mechanism between urban medical facilities,and establishes a spatial directed network for the medical facilities system.Secondly,based on the characteristics of spatial disturbance caused by uncertain pressure,the paper employs the"carrying capacity-load distribution"model to simulate the change of network resilience under the influence of"single pressure"and"multi-source concurrent pressure"respectively.It is found that within the sub-networks featuring a complex structure,the facilities that have a significant impact on network resilience are mostly distributed in areas with scattered facilities,while the sub-networks with a simple structure exhibit greater instability.Subsequently,the paper categorizes medical facilities influencing network resilience into three types:facilities requiring enhanced connectivity,those needing structural optimization,and those focusing on upgrading.Then the distribution patterns,key resilience synergy mechanisms,and existing problems of these facilities are analyzed,based on which targeted planning strategies are proposed.This research methodology and its outcomes are of great significance for enhancing the resilience of the urban public service facilities system and promoting the related planning practice in China.
