东北老工业区矿业城市产业生态系统演化与重构——以辽宁大石桥为例

Evolution and reconstruction of industrial ecosystems of mining cities in the traditional industrial area of northeastern China: A case study of Dashiqiao in Liaoning Province

基于演化经济地理学与产业生态学理论,以辽宁省大石桥市为例,阐明了镁产业的演化过程与特征,建立了镁产业生态系统的结构与功能模型。结果表明:大石桥市镁产业系统演化过程分为起步期、快速期、成熟期、转型期和优化期5个阶段,各个阶段受不同因素的影响呈现出不同的演化特征;基于产业生态学视角的大石桥市镁产业生态系统结构模型包括原生产业子系统、资源环境子系统、外生产业子系统、共生产业子系统和产业创新子系统5个子系统,各子系统之间相互影响与作用,通过系统耦合和物质能量的多级利用形成复杂网络结构,与一般生态系统相似,两者具有同构性与差异性;通过优化调控镁产业生态系统的演化路径与过程,才能实现大石桥市镁产业的生态、经济和社会效益的最大化,以促进生态文明建设。

Based on the theories of evolutionary economic geography and industrial ecology,we mapped the evolutionary process and characteristics of magnesium industry,and established the structure and function model of magnesium industry ecosystem with Dashiqiao City of Liaoning Province as a case. The evolution of magnesium industry system in Dashiqiao was divided into five phases： initial phase,fast phase,mature phase,transitional phase,and optimizing phase.Each phase presented different evolutionary characteristics due to diverse influencing factors.From the perspective of industrial ecology,the structural model of magnesium industry ecosystem in Dashiqiao included five subsystems： primary industrial subsystem,resource and environment subsystem,exogenous industrial subsystem,symbiosis industrial subsystem,and industrial innovation subsystem. The five subsystems interacted with each other and formed a network through systematic coupling and multi-level utilization of material and energy. This structure is similar to a general ecosystem,both of which have the characteristics of isomorphism and difference. Regulating the evolutionary path and process of magnesium industry ecosystem can maximize ecological,economic and social benefits and further promote the construction of ecological civilization of magnesium industry in Dashiqiao.
