Adaptability assessment of industrial ecological system of mining cities in Northeast China

Abstract

Adaptation is a wise choice for industrial ecosystem to face up the inevitable environment changes.It also provides a new paradigm for the study of interaction mechanisms and processes of coupled industrial ecosystem.There are a lot of mining cities in Northeast China,which approach their middle-age or old-age of resources exploitation.Faced with their disappearing superior status in resources problems,the subject on how to adjust the industrial ecosystem to the possible changes in the future,has become urgent in revitalizing the old industrial base of Northeast China.Based on a detailed discussion about the conception of industrial ecosystem adaptation of mining cities,the essay establishes an industrial adaptability assessment index system and model of mining cities from the aspects of adaptation factors of vulnerability,sensitivity,stability and resilience.According to the model,the industrial ecosystem adaptability,including regional differentiation,types and influencing factors of mining cities is evaluated.From a view of different resource types,the average score of industrial ecosystem adaptation shows a trend of metallurgical citiesmulti-resources citiescoal citiespetroleum cities.From a view of regional differences,it shows a trend of LiaoningJilinHeilongjiang;from a view of development stages,it has a trend of old-agedmiddle-agedjuvenile-aged;from a view of mining city size,it shows a trend of mega-citiesbig citiesmedium-sized cities.Then a cluster analysis method is applied to categorize the industrial ecosystems into four types: high adaptability and harmonious development between industry and ecology,high adaptable capacity and environmental development first,low adaptability and harmonious development between industry and ecology,low adaptable capacity and environmental development first.
