MEASUREMENT OF BEIJING'S URBAN COMPREHENSIVE RESILIENCE BASED ON DISSIPATIVE STRUCTURE THEORY
Quantitative measurement of urban comprehensive resilience is a basic step in marking urban resilience level and leading urban eco-civilization construction.This paper,viewing from dissipative structure theory,selects social,economical,ecological and infrastructural resilience and their 21 sub-categories and uses entropy TOPSIS model to quantitatively measure Beijing's 2016 to 2019 urban comprehensive resilience based on urban giant system entropy.Beijing's 2016 to 2019 urban comprehensive resilience has been rising over time with its average showing a trend of"rising-stabilizing-rising",resilience index between 0.30 to 0.76.Beijing's top 3 in urban comprehensive resilience index are Chaoyang,Haidian and Xicheng districts,at 0.76,0.74 and 0.55 respectively.Beijing urban comprehensive level can be divided into five levels,low,relatively low,middle,relatively high and high based on the resilience index,of which low and relatively low are 82%of the total districts,suggesting an overall low resilience level and varying spatially,in a distributing pattern of"north-low,southeast-relatively-high,center-high".Their resilience levels are impacted by governmental investments and natural resources abundance of advantages and disadvantages,of which Chaoyang and Haidian districts are relatively high,and Chaoyang's infrastructural resilience level is much higher than others,while Mentougou,Fangshan and Huairou districts are of more ecological resilience.This paper presents approaches to urban comprehensive resilience on controlling producing system's internal entropy,increasing inputting system's negative entropy,promoting urban reviving,upgrading infrastructures and ecological construction.
